The worst mistake you can make when defending the Christian worldview

2 Comments

So, this is just an advice post for doing apologetics.

Here are three situations I’ve run into while doing apologetics in the last month.

First situation. I was talking with a lady who is an atheist. I had a copy of “God’s Crime Scene” in my hand, and she asked me about it. I told her that it was a book written by the guy who solved the homicide case that I asked her to watch on Dateline. She remembered – it was the two-hour special on the woman who was killed with a garrotte. She pointed at the book and said “what’s in it?” I said, it has 8 pieces of evidence that fit better with a theistic worldview than with an atheistic one, and some of them scientific. Her reply to me was – literally – “which denomination do you want me to join?”

Second situation. I was talking with a friend of mine who teaches in a Catholic school. She was telling that she got the opportunity to talk to her students about God, and found out that some of them were not even theists, and many of them had questions. So she asked them for questions and got a list. The list included many hard cases, like “what about the Bible and slavery” and “why do Christians oppose gay marriage?” and so on.

Third situation. Talking to a grad student about God’s existence. I’m laying out my scientific arguments for her, holding up the peer-reviewed papers for each discovery. I get to the Doug Axe paper on protein folding probabilities, and she holds up her hand. One question: “Am I going to Hell?”

So think about those three situations. In each case, the opponent is trying to reject Christianity by jumping way, way ahead to the very end of the process. When you do Christian apologetics, you do not take the bait and jump to the end of the process dealing with nitty gritty details until you have made your case for the core of the Christian worldview using your strongest evidence. Let me explain.

So, your strongest evidence as a Christian are the scientific arguments, along with the moral argument. Those would include (for starters) the following:

  1. kalam cosmological argument
  2. cosmic fine-tuning
  3. galactic and stellar habitability
  4. origin of life / DNA
  5. molecular machines / irreducible complexity
  6. the moral argument

The problem I am seeing today is that atheists are rejecting discussions about evidence because they think that all we are interested in is getting them to become Christians. Well, yes. I want you to become a Christian. But I know perfectly well what that entails – it entails a change of life priorities. Both of the women I spoke to are living with their boyfriends, and the kids in the Catholic school just want to have fun. None of them wants to believe in a God who will require self-denial, self-control, and self-sacrifice. Nobody wants God to be in that leader position in their lives. Christianity is 100% reversed from today’s me-first, fun-seeking, thrill-seeking, fear-of-missing-out travel spirit of the age.

So, how to answer all these late-game questions? The answer is simple. You don’t answer any late-game questions until the person you are talking with accounts for the widely-accepted data in your list. These are things that have got to be accepted before any discussion about minor issues like one angel vs two angels at the empty tomb can occur. When we discuss all the basic issues where the evidence is the strongest, then we can go on to discuss issues where the evidence is debatable, then finally, in the last bits before the end, we can discuss these other kinds of questions.

How to explain why this process must be followed to the person who asks specific questions about minor issues? Simple. You explain that your goal is not to get them to become a Christian right now. That you want to let them believe anything thing they want. That’s right. They can believe anything they want to believe. As long as what they believe is consistent with the evidence. And what I am going to do is give them the evidence, and then they can believe whatever they want – so long as it’s consistent with the evidence.

So, for example, I’m going to tell them 3 pieces of evidence for a cosmic beginning of the universe: the expanding universe (redshift), the cosmic microwave background radiation, and the light element abundances. That’s mainstream science that shows that the universe came into being out of nothing, a finite time in the past. And I will charge them not to believe in any religion that assumes that the universe has always been here. For example, Mormonism is ruled out, they believe in eternally existing matter. See how that works? Hey, Ms. Atheist. You can believe anything you want. As long as what you believe is consistent with the evidence. 

I think this approach of not letting them rush you to the end at the beginning is important for two reasons. First, we can get our foot in the door to talk about things that are interesting to everyone, in a non-stressed environment. Everyone can talk about evidence comfortably. Second, we show that we hold our beliefs because we are simply letting evidence set boundaries for us on what we are allowed to believe. We can’t believe not-Christianity, because not-Christianity is not consistent with the evidence. And you start with the most well-supported evidence, and eliminate worldviews that are falsified by the most well-supported evidence. Atheism actually gets falsified pretty quickly, because of the scientific evidence.

So, that’s my advice. Had a friend of mine named William try this out about a week ago. It went down like this:

William to me:

This guy I know messaged me and bragged for a while about how easy he can dismantle Christianity. He said: “present the gospel to me as you understand it. I’ll simply ask questions to demonstrate it is not worth your belief.”

WK to William:

First of all, he isn’t allowed to just sit there and poke holes in your case, he has to present a positive case for atheism. Second, don’t discuss Christianity with him at all until you first discuss the evidence for theism – start with the good scientific evidence.

And William wrote this to his friend:

The way I’m wired is that I process all competing theories and go with the best one. By doing a comparative analysis of worldviews I find that Christian theology easily explains the most about the world I find myself living in.

I’m pretty sure that a God of some sort exists because of the scientific evidence for the origin of the universe and the fine tuning in physics. From there I find it quite intuitive that if a God went through the trouble of creating and tuning a universe for life that this God likely has some sort of interest in it and has revealed Himself to humanity in some way.

From there I can look at the major world religions and compare them to see which one explains the past and the present the best. Christianity easily comes out on top.

And then a few days later, I got this from William:

I finally got the agnostic to tell me what he thinks about origin and fine tuning. When I started pointing out that his views were unscientific, he blew a gasket, called me dishonest and told me he didn’t want to discuss anything further.

And that’s where you want to be. Cut off all discussions where the challenger tries to jump to the end and get you to debate the very last steps of your case. Present the strongest evidence for your core claims, and get him to account for this evidence within his own worldview. Lead the discussion with public, testable evidence. All warfare depends on picking the terrain, weapons and tactics that allow you to match your strength against your opponent’s weakness.

William Lane Craig on the unexpected applicability of mathematics to nature

2 Comments

 

You might remember that Dr. Craig used a new argument in his debate with Lawrence Krauss in Melbourne, Australia.

My notes on the debate record it thus:

The unreasonable effectiveness of mathematics:

  • The underlying structure of nature is mathematical – mathematics is applicable to nature
  • Mathematical objects can either be abstract objects or useful fiction
  • Either way, there is no reason to expect that nature should be linked to abstract objects or fictions
  • But a divine mind that wants humans to understand nature is a better explanation for what we see

And now Dr. Craig has expanded on it in the Q&A section of his Reasonable Faith web site.

The question:

Dear Dr Craig

Firstly can I thank you for all your work. My faith in Christ has been enormously strengthened through studying your work in apologetics in particular and I have grown in confidence in my Christian witness.

My question relates to numbers and mathematics as a whole. On the Defenders podcast you state that as God is the only self-existent, necessary being, numbers and mathematical objects, whilst being useful, don’t actually exist as these too would exist necessarily and independently of God. If this is the case, how can it be that mathematics is so easily applied to the natural world? Surely if mathematics only existed in our minds, we would expect to see no correlation between it and how the physical world actually is?

Excerpt from the answer:

As philosopher of mathematics Mary Leng points out, for the non-theistic realist, the fact that physical reality behaves in line with the dictates of acausal mathematical entities existing beyond space and time is “a happy coincidence” (Mathematics and Reality [Oxford: Oxford University Press, 2010], p. 239). Think about it: If, per impossibile, all the abstract objects in the mathematical realm were to disappear overnight, there would be no effect on the physical world. This is simply to reiterate that abstract objects are causally inert. The idea that realism somehow accounts for the applicability of mathematics “is actually very counterintuitive,” muses Mark Balaguer, a philosopher of mathematics. “The idea here is that in order to believe that the physical world has the nature that empirical science assigns to it, I have to believe that there are causally inert mathematical objects, existing outside of spacetime,” an idea which is inherently implausible (Platonism and Anti-Platonism in Mathematics [New York: Oxford University Press, 1998], p. 136).

By contrast, the theistic realist can argue that God has fashioned the world on the structure of the mathematical objects. This is essentially what Plato believed. The world has mathematical structure as a result.

This argument was also made by mechanical engineering professor Walter Bradley in a lecture he gave on scientific evidence for an intelligent designer. You can read an essay that covers some of the material in that lecture at Leadership University.

Excerpt:

The physical universe is surprising in the simple mathematical form it assumes. All the basic laws of physics and fundamental relationships can be described on one side of one sheet of paper because they are so few in number and so simple in form (see table 1.1).

[…]It has been widely recognized for some time that nature assumes a form that is elegantly described by a relatively small number of simple, mathematical relationships, as previously noted in table 1.1. None of the various proposals presented later in this chapter to explain the complexity of the universe address this issue. Albert Einstein in a letter to a friend expressed his amazement that the universe takes such a form (Einstein 1956), saying:

You find it strange that I consider the comprehensibility of the world to the degree that we may speak of such comprehensibility as a miracle or an eternal mystery. Well, a priori one should expect a chaotic world which cannot be in any way grasped through thought. . . . The kind of order created, for example, by Newton’s theory of gravity is of quite a different kind. Even if the axioms of the theory are posited by a human being, the success of such an enterprise presupposes an order in the objective world of a high degree which one has no a priori right to expect. That is the “miracle” which grows increasingly persuasive with the increasing development of knowledge.

Alexander Polykov (1986), one of the top physicists in Russia, commenting on the mathematical character of the universe, said: “We know that nature is described by the best of all possible mathematics because God created it.” Paul Davies, an astrophysicist from England, says, “The equations of physics have in them incredible simplicity, elegance and beauty. That in itself is sufficient to prove to me that there must be a God who is responsible for these laws and responsible for the universe” (Davies 1984). Successful development of a unified field theory in the future would only add to this remarkable situation, further reducing the number of equations required to describe nature, indicating even further unity and integration in the natural phenomena than have been observed to date.

The whole paper that started this off is called “The Unreasonable Effectiveness of Mathematics”, and it is a must read for advanced Christian defenders. You can read the whole thing here.

What are undesigned coincidences, and how are they used in apologetics?

1 Comment

When you’re reading the Bible, you may find passages in one book that are mysterious on their own, but then they make sense if you add missing details from a parallel account from a different source inside or even outside the Bible. I think these “undesigned coincidences” are helpful for answering the question of that skeptics often ask: “is the Bible history or myth?” Let’s see some examples.

So, there are two kinds of undersigned coincidences. In the “internal” kind, the clearing up is done by another source in the same book. In the external kind, the clearing up is done by a source outside the same book.

Here’s an article from Apologetics UK with some internal examples:

In John 6:1-7, we are told:

Some time after this, Jesus crossed to the far shore of the Sea of Galilee (that is, the Sea of Tiberias), and a great crowd of people followed him because they saw the signs he had performed by healing the sick. Then Jesus went up on a mountainside and sat down with his disciples. The Jewish Passover Festival was near.When Jesus looked up and saw a great crowd coming toward him, he said to Philip, “Where shall we buy bread for these people to eat?” He asked this only to test him, for he already had in mind what he was going to do.Philip answered him, “It would take more than half a year’s wages to buy enough bread for each one to have a bite!”

Now, Philip is a fairly minor character in the New Testament. And one might, naturally, be inclined to wonder why Jesus hasn’t turned to someone a little higher in the pecking order (such as Peter or John). A partial clue is provided in John 1:44: “Philip, like Andrew and Peter, was from the town of Bethsaida.” Likewise, John 12:21 refers to “Philip, who was from Bethsaida in Galilee”

And what is so significant about Philip being from the town of Bethsaida? We don’t learn this until we read the parallel account in Luke’s gospel (9:10-17). At the opening of the account (verses 10-11) we are told, “When the apostles returned, they reported to Jesus what they had done. Then he took them with him and they withdrew by themselves to a town called Bethsaida, but the crowds learned about it and followed him. He welcomed them and spoke to them about the kingdom of God, and healed those who needed healing.”

And so, we are informed by Luke that the event was actually taking place in Bethsaida — the town from which Philip was from! Jesus thus turns to Philip, whom, he believed, would be familiar with the area. Notice too that Luke does not tell us that Jesus turned to Philip.

But it gets even more interesting still. In Matthew 11, Jesus denounces the unrepentant cities, saying, “Woe to you, Chorazin! Woe to you, Bethsaida! For if the miracles that were performed in you had been performed in Tyre and Sidon, they would have repented long ago in sackcloth and ashes.” The reader is left wondering what miracles were performed in these cities. We are not told in Matthew’s gospel. It is only in light of Luke’s account of the feeding of the five thousand (chapter 9), in which we are told of the event’s occurrence in Bethsaida, that this statement begins to make sense!

This one is pretty clever:

In Matthew 2 6:67-68, we read, “Then they spat in His face and beat Him; and others struck Him with the palms of their hands, saying, “Prophesy to us, Christ! Who is the one who struck You?”” This raises the natural question, why are they asking “Who hit you?” It is not until we read the parallel account in Luke’s gospel (22:64) that we learn that they had blindfolded him, thereby making sense of their taunts “Who hit you?”

Another one:

In Luke 23:1-4, w e read,
Then the whole assembly rose and led him off to Pilate. And they began to accuse him, saying, “We have found this man subverting our nation. He opposes payment of taxes to Caesar and claims to be Messiah, a king.”

So Pilate asked Jesus, “Are you the king of the Jews?”

“You have said so,” Jesus replied.

Then Pilate announced to the chief priests and the crowd, “I find no basis for a charge against this man.”
On the surface, this seems to be a rather strange declaration to make. Jesus has just declared Himself to be a King, and has been charged with subverting the nation and opposing paying taxes to Caesar. Why has Pilate found no basis for a charge against him?

The answer lies in the parallel account in John’s gospel (18:33-38):

Pilate then went back inside the palace, summoned Jesus and asked him, “Are you the king of the Jews?”

“Is that your own idea,” Jesus asked, “or did others talk to you about me?”
“Am I a Jew?” Pilate replied. “Your own people and chief priests handed you over to me. What is it you have done?”

Jesus said, “My kingdom is not of this world. If it were, my servants would fight to prevent my arrest by the Jewish leaders. But now my kingdom is from another place.”

“You are a king, then!” said Pilate.

Jesus answered, “You say that I am a king. In fact, the reason I was born and came into the world is to testify to the truth. Everyone on the side of truth listens to me.”

“What is truth?” retorted Pilate. With this he went out again to the Jews gathered there and said, “I find no basis for a charge against him.

It is only when you read John’s account that you learn that Jesus had told Pilate that “My kingdom is not of this world. If it were, my servants would fight to prevent my arrest by the Jewish leaders. But now my kingdom is from another place.”

And the same article has some external undesigned coincidences:

In Matthew 2:22, we are told:

But when [Joseph] heard that Archelaus was reigning in Judea in place of his father Herod, he was afraid to go there. Then after being waned by God in an dream, he left for the regions of Galilee…

Josephus’ Antiquities 17.3.1 tells us that the domain of Herod the Great was divided among his sons, with Archelaus having authority in Judea but not in Galilee, which was governed by his younger brother, Herod Antipas.

We also know that Archelaus had acquired quite a bloody reputation (e.g. Antiquities 17.13.1-2 and 17.9.3). The latter of these references describes how Archelaus slaughtered 3,000 Jews at Passover. Thus, Joseph decides not to return to Judea and, instead, goes further north to the regions of Galilee, governed by Herod Antipas.

And another one:

In Matthew 2:22, Archeleaus is reigning as king in Judea; in Matthew 27:2, Pilate is governor of Judea; in Acts 12:1, Herod is king of Judea; and in Acts 23:33, Felix is governor of Judea. This becomes extremely confusing.

But here’s the thing: Josephus attests to the accuracy of every one of these titles. Herod the Great was made King of Judea by Mark Anthony. Archelaus was deposed in the year 6 A.D., after only a ten-year reign, and a series of procurators ruled over Judea (of whom Pilate was fifth). The Herod of Acts 12 is Agrippa I. He was made king by Claudius Caesar. After his death, Judea was, once again, placed under the government of procurators (one of them being Felix).

And another one:

When Luke tells us of the riot in Ephesus, he reports that the city clerk tells the crowd that “There are proconsuls”. A proconsul is a Roman authority to whom a complaint may be taken. Normally, there was only one proconsul. Just at that particular time, however, there seems to have been two as a result of the assassination of Silanus (the previous proconsul) by poisoning in the Fall of AD 54, by the two imperial stewards at the urging of Nero’s mother. This event is independently documented by Tacitus in his Annals (13.1). Indeed, Luke’s accuracy has allowed historians to date the event which Luke narrates with incredible precision since we know when Silanus was poisoned.

If you think that these are clever, then share this post, and encourage your non-Christian friends and family to consider one of the many reasons why so many scholars have considered the New Testament books to be so reliable.

I wish that Christian parents and pastors were more thoughtful about how they present the Bible to young people. Instead of just saying “the Bible says” and praising blind faith acceptance of the Bible, why don’t we think a little harder, and look for some confirmation of the Bible from historical methods like undesigned coincidences, and from non-Biblical authors, and from archaeology, etc.? Surely adding more evidence for taking the Bible seriously is the right approach, if the goal is to be persuasive? It’s not like we’re see good results from the current “blind faith” approach to raising Christian children, right?
