When talking with a non-Christian, make truth – not behavior – the main issue

Pastor Matt posted about something that I think all Christian apologists believe, deep down. (H/T The Poached Egg)

He writes:

Typically, the church has defined loving one’s neighbor as in line with Jesus’ parable of the Good Samaritan (Luke 10:25-37) and Christ’s teaching in passages such as Matthew 25:31-46, in which we are commanded to love the imprisoned, the homeless, the hungry, etc. as if they were Jesus himself. Of course all believers should do so whether by volunteering at a soup kitchen or donating money to ministries like World Help.

But there is more to loving one’s neighbor these days than caring for the poor, as important as that is.  Those of us who live in a first world western country now dwell in a post-Christian society.  Our neighbors are inundated with naturalism masquerading as good science and sound philosophy.  Non-Christians believe the faith is intellectually vacuous.

It shocks many people when those trained in apologetics point out that atheists cannot answer questions like, “How did the universe come into existence?” “Why is our planet so finely tuned for life despite all the odds against it?” “How did life begin?” “Why do humans have consciousness?” “How is there truth or right and wrong without God?” “Why did the disciples die horrible deaths as impoverished traveling peasants rather than deny the resurrection of Jesus?”, etc.

If we are to help bring our neighbors to saving faith, we must first destroy their false ideas of what Christianity is and is not.  That means we must preach the Gospel (2 Cor. 5:21), knock down specious views of the faith and present the truth of what we believe.

Apologetics is not just an intellectual exercise for nerds like me or a debate to be won on college campuses but an increasing tool in loving our neighbors.  For if they do not understand the faith, they will likely not come to faith and that is what the God we love wants and how we must show love to our neighbors.  So, let’s study not just to win arguments but to love others.

That reminds me of 2 Corinthians 10:3-5. Our job is to beat up on false ideas and speculations.

Pastor Matt’s point is critical, I think. Just stop and think for a minute about your non-believing co-workers. Do they know that the universe began to exist? Do they know that the initial conditions and the cosmological constants have to be finely tuned to support things like galaxies, stars, planets and elements heavier than hydrogen? Do they know how much information is in a protein, and how many proteins would be needed to make the first living cell? Do they know what it takes to make a planet that can support life? What facts from the gospels and the Pauline letters pass the tests for historicity? What is the best explanation of those minimal facts?

These are the facts that we share when we discuss spiritual things with people. They are not Christian facts, they are public, testable facts. And yet, almost no one in the culture who is not already a believer is curious to find out these things on their own. But without the evidence, how are they supposed to take the first step towards a relationship with God through Jesus Christ? It’s not possible. This is a propositional faith, and we know it’s true by evidence. To share the evidence with someone so they can decide is as loving as sharing the evidence about retirement planning, or the evidence about nutrition, or the evidence about fitness and exercise, or the evidence about career planning. When you love someone, you tell them the facts, and then they decide. Evangelism is the same thing.

Here’s something from a recent post by J. Warner Wallace, where he talks about doing apologetics with people who have not yet decided whether God exists or not.

The Undecided

In many ways, this group holds the most promise. People who are undecided usually fall into two categories. Some have never really given the issue much thought. They’re neither for nor against; they’ve simply been living unaware. You may be the first person to introduce them to the issues you are trying to share. If so, remember the importance of a first impression. What you say or do will have an impact on the work of those who follow you. The second group of “undecideds” are people who have given the issue some thought, but are just beginning to make their decision. For this group of people, your defense of Christianity may very well be the deciding factor. The responsibility you and I have with the undecided is daunting, but it’s a privilege to play a small part in their decision.

OK, so I want to make a point about this. So often, I see Christian parents and leaders trying to focus on changing people’s behaviors, and not by giving them evidence. Instead of trying to convince them about what’s true, they tell them Bible verses, or maybe tell them they are going to Hell. But given what Matt and J. Warner said, I don’t want us to be focused on changing outward behavior. I want us to be focused on showing people what is true and showing our work – how we arrived at these true beliefs. You are doing Christianity wrong if you focus on getting behaviors from people by shaming them, overpowering them or scaring them.

So in my case, I’m not trying to get non-Christians to act like Christians when they have no reasons to be one. I’m trying to get them to settle on true beliefs – so that each of them and God can shake hands and be reconciled, responding to his drawing them of their own free will. Then, they can decide how they are going to act. And how they act might be even better than what we had in mind for them when all we wanted was for them to quit swearing and eat their vegetables. The Christian life is bigger than just making people do what we want them to do.

Robin Collins lectures on fine-tuning for discoverability from particle physics

Christianity and the progress of science
Christianity and the progress of science

Here’s the lecture:

This lecture is 29 minutes long, the Q&A is 15 minutes. I highly recommend this lecture to all audiences of all levels of ability, for the simple reasons that apart from the content, this lecture is a how-to clinic in the tone, body language, slides and so on for you to use when trying to be persuasive when making your case. Science is king in this lecture. The scientific method is defined and applied in a winsome way. Making science understandable should be the bread and butter approach to Christian apologetics, and this lecture rivals the Mike Strauss lecture at Stanford University and the Mike Strauss lecture at the University of Texas – Dallas as the ideal lectures for showing that. It’s not just the scientific material that makes this lecture by Collins work, it’s the narrative and the style that make the lecture work.

About Robin Collins:

Robin Collins (PhD, University of Notre Dame, 1993), is professor of philosophy at Messiah College, Grantham, PA specializing in the area of science and religion.  He has written over twenty-five articles and book chapters on a wide range of topics, such as the fine-tuning of the cosmos as evidence for the existence of God, evolution and original sin, the Doctrine of Atonement, Asian religions and Christianity, and Bohm’s theory of quantum mechanics.  Some of his most recent articles/book chapters are “Philosophy of Science and Religion” in The Oxford Handbook of Science and Religion, “Divine Action and Evolution” in The Oxford Handbook of Philosophical Theology (2009)  “The Multiverse Hypothesis: A Theistic Perspective,” in Universe or Multiverse? (Cambridge University Press), and “God and the Laws of Nature,” in Theism or Naturalism: New Philosophical Perspectives (Oxford University Press, forthcoming).  He recently received a grant from the John Templeton Foundation to finish a book that presents the case for design based on physics and cosmology,  tentatively entitled The Well-Tempered Universe: God, Cosmic Fine-tuning, and the Laws of Nature.

His thesis in one slide:

Fine-tuning for discoverability
Fine-tuning for discoverability – the DLO thesis

Summary:

  • Thesis: the universe is more intelligible than we would expect it by chance
  • The regular fine-tuning argument says that complex embodied observers are very rare
  • But the number of highly-discoverable universes that have complex embodied observers is rarer still
  • Why do we exist in a highly-discoverable universe?
  • Can we quantify and test discoverability?
  • Yes: by varying fundamental parameters and seeing how it affects discoverability
  • Conclusion of his calculations: The Discoverability-Liveability Optimality range is an even smaller range within the Liveablity Optimality range of the standard fine-tuning argument
  • Fine-tuning #1: the fine structure constant, governs the strength of the electro-magnetic force
  • If larger, wood-burning fire becomes impossible because fires won’t stay lit, and therefore forging metals becomes unlikely
  • If smaller, wood-burning fires won’t go out, e.g. – from lightning strikes, so that wood would be less accessible
  • Other constraints: smaller value decreases effectiveness of light microscopes, drastically lowers efficiency of transformers and motors
  • Fine-tuning #2: the cosmic microwave background radiation (CMBR), radiation left over from the Big Bang
  • humans need to discover the CMBR in order to confirm the Big Bang creation out of nothing, and it depends on baryon/pothon ratio
  • his calculations show that the actual value of CMBR is exactly at the peak for detectability by humans
  • if baryon/photon ratio larger, CMBR is less discoverable
  • if baryon/photon ratio smaller, CMBR is less discoverable
  • Fine-tuning #3: parameters related to subatomic particles are fine-tuned for their discovery and usefulness, e.g. – the bottom quark, the charm quark, the tau lepton and the Higgs Boson
  • the lifetime of the particles affects their usefulness to scientists who want to investigate the Standard Model of physics
  • decay rates of these subatomic particles are related to several of the finely-tuned parameters
  • for example, the mass of the bottom quark is finely-tuned for its discoverability by scientists
  • the tau lepton and the charm quark are similarly fine-tuned for disoverability
  • the mass of the Higgs boson is finely-tuned for discoverability and for making further discoveries
  • Conclusion: the DLO thesis is strongly confirmed – this is an even greater degree of fine-tuning that the already astonishing probabilities of the fine-tuning for complex, embodied intelligent beings
  • The formalized version of the philosophical argument based on this evidence is impervious with some of the traditional objections to the standard fine-tuning argument
  • #1 multiverse/selection effect: it is not subject to multiverse / observer selection objections
  • #2 normalizeability: it is not subject to the McGrew-Vestrup objection because the range of possible values is finite not infinite
  • #3 falsifiability: it makes falsifiable predictions, and in fact Collins’ earlier calculations of the CMBR discoverability contained an error that falsified the thesis – until he found the error and corrected for it
  • #4 usefulness: it gives clues about the Creator’s purpose for us, namely that the universe was created for us to be able to do science and find evidence of the Creator’s existence – there is no expectation for us to exercise blind faith, trust in God is meant to be a plausible deduction from the progress of experimental science

Earlier, I blogged about a Robin Collins lecture on the fine-tuning that allows complex, embodied life to exist. Another must-see lecture. If you are looking for something to study in university, and you have funding, then physics, mathematics and philosophy are the best places to be for a Christian scholar.

William Lane Craig lectures on naturalistic alternatives to the Big Bang

William Lane Craig lecturing to university students
William Lane Craig lecturing to university students

Here’s the lecture, which was given in 2004 at the University of Colorado, Boulder.

This lecture might be a little advanced for beginners, but if you stretch your mind first, you shouldn’t tear anything. (Note: standard disclaimers apply if you do tear something!)

The description of the video states:

This is quite simply one of the best lectures William Lane Craig (a philosopher of science) has given. Craig explores the origins of the universe. He argues for a beginning of the universe, while refuting scientific models like the Steady State Theory, the Oscillating Theory, Quantum Vacuum Fluctuation Model, Chaotic Inflationary Theory, Quantum Gravity Theory, String Theory, M-Theory and Cyclic Ekpyrotic Theory.

And here is the description of the lecture from Reasonable Faith:

A Templeton Foundation lecture at the University of Colorado, Boulder, laying out the case from contemporary cosmology for the beginning of the universe and its theological implications. Includes a lengthy Q & A period which features previous critics and debate opponents of Dr. Craig who were in attendance, including Michael Tooley, Victor Stenger, and Arnold Guminski.

Craig has previously debated famous atheists Stenger and Tooley previously. And they both asked him questions in the Q&A time of this lecture. Imagine – having laid out your entire case to two people who have debated you before and who know your arguments well. What did they ask Craig, and how did he respond?

The scientific evidence

The Big Bang cosmology that Dr. Craig presents is the standard model for how the universe came into being. It is a theory based on six lines of experimental evidence.

Scientific evidence:

  1. Einstein’s theory of general relativity (GTR)
  2. the red-shifting of light from distant galaxies implies an expanding universe
  3. the cosmic background radiation (which also disproves the oscillating model of the universe)
  4. the second law of thermodynamics applied to star formation theory
  5. hydrogen-helium abundance predictions
  6. radioactive element abundance predictions

It’s probably a good idea to be familiar with these if you are presenting this argument, because experimental science is a reliable way of knowing about reality.

Published research paper

This lecture by Dr. Craig is based on a research paper published in an astrophysics journal, and was delivered to an audience of students and faculty, including atheist physicist Victor Stenger and prominent atheist philosopher Michael Tooley, at the University of Colorado at Boulder.

Here’s the peer-reviewed article that the lecture is based on.

Here’s the abstract:

Both cosmology and philosophy trace their roots to the wonder felt by the ancient Greeks as they contemplated the universe. The ultimate question remains why the universe exists rather than nothing. This question led Leibniz to postulate the existence of a metaphysically necessary being, which he identified as God. Leibniz’s critics, however, disputed this identification, claiming that the space-time universe itself may be the metaphysically necessary being. The discovery during this century that the universe began to exist, however, calls into question the universe’s status as metaphysically necessary, since any necessary being must be eternal in its existence. Although various cosmogonic models claiming to avert the beginning of the universe predicted by the standard model have been and continue to be offered, no model involving an eternal universe has proved as plausible as the standard model. Unless we are to assert that the universe simply sprang into being uncaused out of nothing, we are thus led to Leibniz’s conclusion. Several objections to inferring a supernatural cause of the origin of the universe are considered and found to be unsound.
