The Key to Successful Debating

By William Lane Craig Aug. 28, 2015 9:00 a.m. Apologetics, Philosophy

Dear Dr. Craig,

You were the first Christian apologist I came across when I was researching a credible answer from Christianity to Atheist and Islam in 2002. Since then I have been following you through different medium on the internet. May God bless you for bringing the Christian truth with precision and clarity and with so much needed nuances.

I was re-watching your debate with Dr. Richard Carrier on the Resurrection of Jesus. I can't remember anyone really dismantling his case as you did. So I wondered how do you do to prepare for a debate? Most speakers are good at their opening speech but fair less well during the rebuttals, failure you seem immune to. Do you also prepare the rebuttals before your debates? If yes, how on earth do you do that since you can't possibly know what the opponent would say? ...

Are There Uncreated Abstract Objects?

By William Lane Craig Aug. 21, 2015 9:00 a.m. Apologetics, Philosophy

... I've been reading "Philosophical Foundations for a Christian Worldview" for the past few months and have repeatedly been fascinated by what I am reading. One of my favorite areas of philosophy is ontology, and I was particularly interested in abstract objects. I had heard you explain abstract objects briefly and often in your debates and lectures as one of the only two options for a first cause of the universe. As you've said, abstract objects do not stand in causal relations.

In thinking about this, however, something has come to mind. If abstract objects do not stand in causal relations, what is their relationship with God? Both God and abstract objects are metaphysically necessary beings, meaning that they exist in every possible world. This seems to me to conflict with a theological view that God is the creator of everything. If God didn't exist, nothing would. Though it seems to me that if God didn't exist, abstract objects still would. Thus, it seems that mathematical entities, for instance, would and do exist independently of whether or not God exists ...

Intransigence about Objective Moral Values

By William Lane Craig Aug. 14, 2015 9:00 a.m. Apologetics, Philosophy


The last few weeks I have been working my way through On Guard (and was, needless to say, thrilled by it, just as I was by Reasonable Faith).

I just had a long conversation with a fellow student of our local university. He knows that I am a Christian, and since the topic shifted toward values and ethics, I began asking him questions about his beliefs on the existence of subjective and objective values - based on the premises that

1. If God does not exist, then objective values do not exist.

2. Objective Values exist.

3. Therefore, God exists.

It was a very tough conversation (albeit a cordial one), and I am very glad that my friend is still interested in picking up the conversation where we left off (it is now past 3am in Germany) - he seemed surprisingly hooked by the debate, took his time to think his answers through, and was the one to suggest continuing it sometime soon. (I am praying for him to find Christ) ...

Blind Faith

By William Lane Craig Aug. 7, 2015 9:00 a.m. Apologetics, Philosophy

Dr. WIlliam Lane Craig,

On October 21, 2013, you responded to a question by a lifelong Christian who said they were having trouble believing because of reading material from people like Richard Dawkins, and from discussions they had with their atheist friends ( You chided this person (and other Christians like them) very strongly for the "cavalier way" that they "expose themselves to material which is potentially destructive to them." ...

... Personally, I don't understand what the value is of asking questions is, if you consider anyone who doesn't agree with the answers you already have to be "the wrong people." But that's not my main point. I'm more concerned about that first sentence, which sounds more like something you might hear from an imam of ISIS than a prominent Christian philosopher, who believes so strongly that Christianity is a reasonable faith. If Christianity truly is consistent with reality itself, then shouldn't it hold up to scrutiny? ...

Lessons from Time and Creation

By William Lane Craig Jul. 31, 2015 9:00 a.m. Apologetics, Philosophy

Dear Dr. Craig

I am Samuel, I am 20 years old, and I am currently studying for a science degree in Biology and Chemistry at the university of Malta.

An argument which was brought up by my Atheist friend, which is currently studying physics and Chemistry, regarding the origins of the universe. My friend argued that because there was no time prior to the big bang, therefore there was no causal relation involved, because causes require time in order to occur. My response was that this thus implies a cause which transcends time, and I brought up an analogy to help explain it. I said that when a writer writes a story, the cause of the story goes beyond the reality of story timeline. But that does not mean that the story timeline lacks a cause because the cause didn't happen within the parameters of the story's reality. Anyway, my friend was not convinced, so I wanted to see how you would respond to such an argument.

Does the universe have a cause, even when time didn't even exist prior the big bang? ...

Supreme Court’s Re-definition of Marriage

By William Lane Craig Jul. 24, 2015 9:00 a.m. Apologetics, Philosophy

Hello Dr. Craig,

With the recent Supreme court decision regarding same sex marriage I reread some of your Q/A response regarding homosexuality. In a question regarding the connection between interracial marriage and same sex marriage you said "Once we start down that route, anything goes: a man and two women, a man and a child, two men and a goat, etc. I see no reason at all to start down that road." with regards to same sex marriage. My question is does this statement constitute a slippery slope fallacy? My concern is that non believers would easily dismiss it ...

Questions on Time and the Origin of the Universe

By William Lane Craig Jul. 17, 2015 9:00 a.m. Philosophy

Dr. Craig,

My name is Tejas and I'm 13 years old. I admire you and have watched many of your debates. I sincerely request you to answer this question, and thank you for taking your time to read this.

My question regards the Kalam Cosmological Argument, that I have seen you present in some debates. The first part is, is the initial premise on causation refuted if the zero-energy universe hypothesis is true, and what would be the flaws if the universe were a vacuum fluctuation? And regarding the second premise, could you please tell me why you think the presentism ontology of time is true? ...
