Since it’s eclipse time in America, I’ve posted a lecture that talks about intelligent design and eclipses. There are 5 video clips that make up the full lecture.

The playlist for all 5 clips is here.

The lecture

Here’s part 1 of 5:

And the rest are here:

Total time: 43 minutes.

Topics:

  • What is the Copernican Principle?
  • Is the Earth’s suitability for hosting life rare in the universe?
  • Does the Earth have to be the center of the universe to be special?
  • How similar to the Earth does a planet have to be to support life?
  • What is the definition of life?
  • What are the three minimal requirements for life of any kind?
  • Requirement 1: A molecule that can store information (carbon)
  • Requirement 2: A medium in which chemicals can interact (liquid water)
  • Requirement 3: A diverse set of chemical elements
  • What is the best environment for life to exist?
  • Our place in the solar system: the circumstellar habitable zone
  • Our place in the galaxy: the galactic habitable zones
  • Our time in the universe’s history: the cosmic habitable age
  • Other habitability requirements (e.g. – metal-rich star, massive moon, etc.)
  • The orchestration needed to create a habitable planet
  • How different factors depend on one another through time
  • How tweaking one factor can adversely affect other factors
  • How many possible places are there in the universe where life could emerge?
  • Given these probabilistic resources, should we expect that there is life elsewhere?
  • How to calculate probabilities using the “Product Rule”
  • Can we infer that there is a Designer just because life is rare? Or do we need more?

The corelation between habitability and measurability.

  • Are the habitable places in the universe also the best places to do science?
  • Do the factors that make Earth habitable also make it good for doing science?
  • Some places and times in the history of the universe are more habitable than others
  • Those exact places and times also allow us to make scientific discoveries
  • Observing solar eclipses and structure of our star, the Sun
  • Observing stars and galaxies
  • Observing the cosmic microwave background radiation
  • Observing the acceleration of the universe caused by dark matter and energy
  • Observing the abundances of light elements like helium of hydrogen
  • These observations support the big bang and fine-tuning arguments for God’s existence
  • It is exactly like placing observatories on the tops of mountains
  • There are observers existing in the best places to observe things
  • This is EXACTLY how the universe has been designed for making scientific discoveries

Young workers are paying Social Security taxes but will they ever collect benefits?

What if we had no money for anything except entitlement spending?
What if we had no money for anything except interest and entitlements?

The way Social Security taxes work is that you pay 12.4% of your salary, and another 2.9% for Medicare. That’s 15.3%, before any federal, state and local taxes. So, what are you getting for this 12.4% contribution to the Social Security welfare program? You’re supposed to be able to withdraw that money when you retire, but that money isn’t being stored in an account with your name on it. It’s being spent right now on people who are already retired. Will there be money available for you to withdraw when you retire?

If you’re a young person who retires in 2035 or later, the answer is absolutely not.

The Daily Signal has the numbers:

The American people need to know the state of finances of the Social Security program so they can better understand why reform is not only necessary, but absolutely essential. Here are five takeaways from the most recent financial report:

  • $66 Billion Cash-Flow Deficit in 2016

Social Security is still considered solvent and able to pay full benefits because it has accumulated a $2.8 trillion trust fund, but since the entirety of its trust fund consists of IOUs, cash-flow deficits must be financed by general revenue taxes or new public borrowing.

Since 2010, the Old-Age and Survivors Insurance program has taken in less money from payroll tax revenues and the taxation of benefits than it pays out in benefits, generating cash-flow deficits.

  • $14.3 Trillion in Unfunded Obligations

However, this figure assumes that the $2.8 trillion in trust fund reserves are available to be spent. The problem is that these reserves represent liabilities for the U.S. taxpayer. The payroll revenues have been spent and the trust fund was credited with U.S. bonds, which represent claims on the American taxpayer. This is why the actual unfunded obligation is $14.3 trillion.

The trustees report that Social Security’s unfunded obligation has reached $11.5 trillion. That is the difference between what the program is expected to receive in income and what is expected to spend over the 75-year horizon the program’s actuaries consider for projections.

  • Insolvent by 2035

Based on current projections, the Social Security Old-Age and Survivors Insurance trust fund will be depleted by 2035, reducing Social Security’s expenditures automatically to what the program will receive in revenues, regardless of benefits due at that time.

Social Security is only legally permitted to spend funds in excess of its revenues until its trust fund is depleted.

  • 25 Percent Automatic Benefit Cut

What this means for beneficiaries is that in the absence of congressional action, benefits could be delayed or indiscriminately reduced across the board by 25 percent.

Once the Social Security trust fund is depleted, the program will only be able to pay 75 percent of scheduled benefits, based on payroll and other Social Security tax revenues projected at that time.

  • High Costs to Delaying Reform

The trustees highlight that if Congress waits until the trust funds become exhausted, the cost of making the program solvent will be as much as 40 percent higher, meaning significantly greater benefit cuts and/or tax increases for workers and beneficiaries.

There are several key reforms Congress could pursue to preserve benefits for the most vulnerable beneficiaries without increasing the tax or debt burden on younger generations. However, the longer Congress waits the act, the larger the changes that will be necessary to address Social Security’s combined financing shortfall.

Young people working today who retire in 2035 or later will never see a dime of their Social Security contributions. What’s more likely is that the taxes on their income will go even higher. Take a good look at your paycheck, and you will see money being deducted for this entitlement program. This is money you will never see again. It is being used now, to buy the votes of elderly people who vote against reform when they vote Democrat.

The only person to try to do something about these Social Security problems was George W. Bush – a Republican. But his effort to set up private savings accounts was stopped by Democrats, who depend on the votes of the people who collect from Social Security.

These problems are even worse when you realize that Social Security is only one of the entitlement programs that is going bankrupt. There are others – as well as interest on the $20 trillion debt. ($10 trillion of which was added by Obama in his 8 years as Welfare President). Young people: you are paying taxes for programs that will not be there for you when you need them. Stop voting Democrat, because money matters!

If you accept Jesus and become a Christian, will God make you happy?

I have a key that will unlock a puzzling mystery
I have a key that will unlock a puzzling mystery

This is a wonderful, wonderful post from Amy Hall, who writes for the Stand to Reason blog.

She writes:

I had a brief interaction with an atheist on Twitter a couple of weeks ago that unexpectedly turned to the issue of suffering when she said:

You clearly never had a time you were hurt. I don’t mean sick. I don’t mean heart broken. I mean literally a near death experience or rape or abusive relationship…. You can keep floating on a [expletive] cloud thinking Jesus will do everything for you but it’s a lie. What makes you so special?

That surprised me at first because it didn’t seem to have anything to do with the tweet she was responding to, and I was confused as to why she would assume I’d never been through anything traumatic. But then in subsequent tweets, when she revealed she had been raped, it became clear that her trauma had played a central role in her becoming an outspoken, obviously angry “antitheist.” She’s a self-described antitheist now because she thinks Christianity teaches Jesus “will do everything for you” to give you a perfect life, and now she knows that’s a lie. The rape proved her understanding of Christianity false.

So it made sense for her to reason that since I believe Christianity is true, I must still be under the delusion that Jesus is making my life special, which means I obviously never encountered any evil or suffering to shake that delusion.

All right, readers. I don’t want any of you to be thinking that if you become a Christian that these things should be expected to happen:

  • you will feel happy all the time
  • you will be able to sense God’s secret plan for your life through your feelings
  • God’s secret plan for your life will automatically work, even though it’s crazy
  • God will give you a perfect spouse and lots of money without you having to study anything hard, or do any hard work
  • you get permission to do things that that make you happy, even if they are expressly forbidden by the Bible
  • you don’t have to do anything that makes you feel bad (e.g. – talk to non-Christians about Christian truth claims), because God wants you to be happy

No! Where do people get this idea that if they convert to Christianity, then God will become their cosmic butler?

Amy has the answer: (emphasis mine)

Hear me, everyone: This is a failure of the church.

A friend of mine who was deeply suffering once said to me that many Christians are in for “an epic letdown” when they realize their preconceived notions about what God is expected to do for us are false. Pastors who preach a life-improvement Jesus are leading people down this precarious path to disillusionment.

If suffering disproves your Christianity, you’ve missed Christianity. The Bible is filled with the suffering of those whom God loves. The central event of the Bible is one of suffering. Love involves suffering. “We know love by this, that He laid down His life for us; and we ought to lay down our lives for the brethren.” That means suffering.

It’s the church. It’s the focus on happy things and having of happy feelings and happy songs and preaching designed to make us feel good. I would say the comforting devotional reading doesn’t help to make us any tougher or more practical, either. That happy-clappy stuff just gives you a false sense of safety about your precarious situation. God’s job is not to prevent you from suffering. In fact, even if you make really smart, practical decisions, you can expect to get creamed anyway.

Please take 15 minutes and read the book of 1 Peter in the New Testament.

Here’s a summary from GotQuestions.org:

Purpose of Writing: 1 Peter is a letter from Peter to the believers who had been dispersed throughout the ancient world and were under intense persecution. If anyone understood persecution, it was Peter. He was beaten, threatened, punished and jailed for preaching the Word of God. He knew what it took to endure without bitterness, without losing hope and in great faith living an obedient, victorious life. This knowledge of living hope in Jesus was the message and Christ’s example was the one to follow.

Brief Summary: Though this time of persecution was desperate, Peter reveals that it was actually a time to rejoice. He says to count it a privilege to suffer for the sake of Christ, as their Savior suffered for them. This letter makes reference to Peter’s personal experiences with Jesus and his sermons from the book of Acts. Peter confirms Satan as the great enemy of every Christian but the assurance of Christ’s future return gives the incentive of hope.

Practical Application: The assurance of eternal life is given to all Christians. One way to identify with Christ is to share in His suffering. To us that would be to endure insults and slurs from those who call us “goodie two shoes” or “holier than thou.” This is so minor compared to what Christ suffered for us on the Cross. Stand up for what you know and believe is right and rejoice when the world and Satan aim to hurt you.

Recently, I blogged about how suffering is compatible with an all-powerful God, so you might want to read that too if you missed it.

Is the presuppositionalist approach to apologetics Biblical?

Bible study that hits the spot
Bible study that hits the spot

Here’s J.W. Wartick’s take from Always Have a Reason blog.

Excerpt:

Cornelius Van Til pioneered the field of “presuppositional apologetics” primarily through his works Christian Apologetics and The Defense of the Faith. His arguments are easily misunderstood as question begging or viciously circular. Herein, I have presented a brief outline and analysis which reveals that while the presuppositional approach may indeed have some logical faults, the overall system has a certain power to it and can be integrated into a total-apologetic system.

[…]The key to understand here is that Van Til does not accept that there is a neutral reason “out there” by which Christians and non-Christians can arbitrate the truth of Christianity; his point is that there is no neutral ground and that one’s presuppositions will determine one’s end point. Again, he writes, “this [apologetic method] implies a refusal to grant that any area or aspect of reality, any fact or any law of nature or of history, can be correctly interpreted except it be seen in the light of the main doctrines of Christianity” (Christian Apologetics, 124).

However, Van Til takes it even further and argues that one must presuppose the truth of Christianity in order to make sense of reality: ” What is the content of this presupposition, then? It is this: “I take what the Bible says about God and his relation to the universe as unquestionably true on its own authority” (The Defense of the Faith, 253); again, “The Bible is thought of as authoritative on everything of which it speaks. Moreover, it speaks of everything” (Christian Apologetics, 19). Thus, Van Til’s apologetic does not make Christianity the conclusion of an argument; rather, Christianity is the starting presupposition.

The presuppositional approach here cannot be stressed enough. For Van Til, one simply cannot grant to the non-Christian any epistemic point. “We cannot avoid coming to a clear-cut decision with respect to the question as to whose knowledge, man’s or God’s, shall be made the standard of the other. …[O]ne must be determinative and the other subordinate” (The Defense of the Faith 62-63).

What place is had for evidences in Van Til? At some points, he seems to be very skeptical of the use of Christian evidences. In particular, the fact that he argues there is no neutral evaluation grounds between the Christian and non-Christian seems to imply that  there can be no real evaluation of such arguments apart from Christianity. One of Van Til’s most famous illustrations of the use of evidences can be found in The Defense of the Faith pages 332 and following. He uses three persons, Mr. Black (non-Christian), Mr. Grey (Christian non-presuppositionalist), and Mr. White (presuppositional/reformed apologist):

Mr. Grey… says that, of course, the “rational man” has a perfect right to test the credibility of Scripture by logic… by experience… [Mr. Grey then takes Mr. Black a number of places to show him various theistic evidences. Mr. Black responds:] “you first use intellectual argument upon principles that presuppose the justice of my unbelieving position. Then when it it is pointed out to you that such is the case, you turn to witnessing [subjectively].

…At last it dawned upon Mr. White that first to admit that the principles of Mr. Black, the unbeliever, are right and then to seek to win him to the acceptance of the existence of God the Creator… is like first admitting that the United States had historically been a province of the Soviet Union but ought at the same time to be recognized as an independent and all-controlling power… If one reasons for the existence of God and for the truth of Christianity on the assumptions that Mr. Black’s principles of explanation are valid, then one must witness on the same assumption [which makes witnessing wholly subjective.] (p. 332-339)

It can be seen here that even evidences for Van Til must be based within a presupposition. There is no way to look at evidences in the abstract. One can either offer them within the presuppositions of Christianity or outside of Christianity. For Van Til, once one has agreed to offer evidences outside of Christianity, one has granted the presuppositions of the non-believer, and therefore is doomed to fail.

This would include using arguments like the cosmological argument, the fine-tuning argument, arguments from miracles, etc. – including the resurrection. That seems to be Van Til’s view. No evidence allowed – you have to presuppose Christianity is true in order to make sense of the world.

Now, I think we need to make a distinction between using questioning the pre-suppositions of our opponents, as with William Lane’s Craig’s moral argument, Plantinga’s epistemological argument for reason and Menuge’s ontological argument for reason. There are arguments for theism that question the pre-suppositions of an atheist. Certainly, non-theists cannot ground things like morality, free will, consciousness and rationality on atheism. But that’s not what Van Til is saying. He says that an atheist cannot be swayed by evidence unless he first becomes a Christian. I.e. – he is saying that atheist Anthony Flew is lying when he says that evidence caused him to turn to believe in God. On Van Til’s view, that’s impossible.

My view of presuppositional apologetics is that is as a system, it is circular reasoning. It assumes Christianity in order to prove Christianity. But there is an even worse problem with it. It’s not a Biblical way of doing apologetics. It’s man’s way of doing apologetics, not God’s. I think that the best way to understand Van Til’s apologetics is by saying that it really just a sermon disguised as apologetics. The problem is that Van Til’s sermon has no basis in the Bible. Wherever he is getting his view from, it’s not from the Bible. When I look the Bible, I don’t see any Biblical support for the view that pre-suppositional apologetics is the only approved way of defending the faith. Instead, the standard method seems to be evidentialism.

In Romans 1, Paul writes that people can learn about God’s existence from the natural world.

Romans 1:18-23:

18The wrath of God is being revealed from heaven against all the godlessness and wickedness of men who suppress the truth by their wickedness,

19since what may be known about God is plain to them, because God has made it plain to them.

20For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse.

21For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened.

22Although they claimed to be wise, they became fools

23and exchanged the glory of the immortal God for images made to look like mortal man and birds and animals and reptiles.

And in Acts, Peter appeals to eyewitness testimony for the resurrection, and Jesus’ miracles.

Acts 2:22-24, and 36:

22“Men of Israel, listen to this: Jesus of Nazareth was a man accredited by God to you by miracles, wonders and signs, which God did among you through him, as you yourselves know.

23This man was handed over to you by God’s set purpose and foreknowledge; and you, with the help of wicked men, put him to death by nailing him to the cross.

24But God raised him from the dead, freeing him from the agony of death, because it was impossible for death to keep its hold on him.

And finally from the same chapter:

36“Therefore let all Israel be assured of this: God has made this Jesus, whom you crucified, both Lord and Christ.”

Professor Clay Jones of Biola University makes the case that the use of evidence when preaching the gospel was standard operating procedure in the early church. (H/T Apologetics 315)

Intro:

In 1993 I started working for Simon Greenleaf University (now Trinity Law School) which offered an M.A. in Christian apologetics (Craig Hazen was the director). Much of my job was to promote the school and although I had studied Christian apologetics since my sophomore year in high school, I decided I needed to see whether an apologetic witness had strong Biblical precedence.

It does.

As I poured through the Scripture I found that Jesus and the apostles preached the resurrection of Christ as the sign of the truth of Christianity.

What follows are some of the passages which support the resurrection witness.

Here is my favorite verse from his massive list list of verses in favor of the evidential approach to Christian apologetics:

Mat. 12:39-40: A wicked and adulterous generation asks for a miraculous sign! But none will be given it except the sign of the prophet Jonah. For as Jonah was three days and three nights in the belly of a huge fish, so the Son of Man will be three days and three nights in the heart of the earth.

Jesus is saying that the resurrection was deliberately given as a sign to unbelievers to convince them. (“The Sign of Jonah” = the resurrection)

So, I see that God uses nature and miracles to persuade, which can be assessed using scientific and historical methods. Can anyone find me a clear statement in the Bible that states that only pre-suppositional arguments should be used? I could be wrong, and I am willing to be proven wrong. I think we should use the Biblical method of apologetics, not the fallen man’s method of apologetics.

Positive arguments for Christian theism

Are atheists able to perform the greatest moral duty?

Goodness Without God: is it possible?
Goodness Without God: is it possible?

J. Warner Wallace looks at what Jesus says the most important commandment is, and then asks whether atheists can be justified morally if Jesus is right.

He writes:

I was an atheist for the first thirty-five years of my life. While I was a committed (and often aggressive) non-believer, most people who knew me would probably have described me as a “nice guy”. My behavior wasn’t all that different than many of my Christian friends. I worked with many other atheist police officers. We were often suspicious of the Christians in our midst and the people we arrested who claimed to be Christians. Even as atheists we were familiar with Jesus’ directive to “love your neighbor as yourself.” My partner, Tim, used to say, “If there is a good God and a good Heaven, I think I will be there when it’s all over. I’m a good person. I try to ‘do the right thing’. I’m not a bad guy; I put bad people in jail. So I’m not worried about it.” Tim held a “works based” moral worldview and he was sure his good deeds would earn him a spot in Heaven if he was wrong about the existence of God. But Tim (and I) were unfamiliar with Jesus’ teaching in its full context, and now, years later as a Christian, I’ve come to understand why the first part of the “Greatest Command” is even more important than the second.

When approached by a skeptic, Jesus affirmed the greatest commandments of God in the following way:

Matthew 22:35-40
One of them, a lawyer, asked Him a question, testing Him, “Teacher, which is the great commandment in the Law?” And He said to him, “‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ This is the great and foremost commandment. The second is like it, ‘You shall love your neighbor as yourself.’ On these two commandments depend the whole Law and the Prophets.”

Most unbelievers recognize the value of the second half of this command (“You shall love your neighbor as yourself”) but deny the value of the first part (“‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.”) There’s a reason, however, why Jesus listed these two commands in this specific order. The first command (loving God) is the “great and foremost commandment” because it is required to achieve the second command (loving others). You can’t truly do the right thing unless you understand the relationship between these two commands:

Read the rest at Cold Case Christianity.

I’ve made the same point here many times, but I have never been an atheist and I don’t make the point in the same winsome way that Wallace does.

I think his post is worth sending along to any atheists you may know who think themselves justified. I think it is a mistake for people to derive their own version of morality based on the time and place where they are, and then think that picking and choosing the parts they like will justify them with God. Remember, a recent survey of atheists found that 97% of them favor abortion rights. I think this is consistent with the atheist view that there are no human rights, including a right to life. Moreover, in my experience, I have found that most atheists have no problem with the government stomping all over the consciences of Christian business owners when it comes to things like gay rights. It’s important to show them that there is a standard independent of their personal opinions, justifications and rationalizations. And that they don’t measure up to it.
