Many debates between a Christian and atheist go something like this:

Christian: “God exists because we see the influences of a Creator all around us. Only His existence can make sense of everything else.”

Atheist: “Okay, so God exists. Now why are you a Christian and not Jewish or Mormon or Islamic?”

Christian: “Ummm” (insert awkward relativism like: “For me Christianity makes the most sense”) …

If you don’t think this fumbling happens, I would encourage you to listen to the recent McGrath/Dawkins debate. When a Christian debates an atheist – as you hear in this and many other debates – there comes a moment when the debate takes an awkward turn. The question changes from the existence of God to why the Christian has chosen his/her religion over all the others. It’s an awkward moment because it reveals that the Christian was debating from rationalism, not pleading obedience to God’s revelation. This misunderstanding gets exposed with one simple question.

So you believe in God. What makes Jesus Christ your god of choice? It seems the only objective answer to this most pressing question is to say God is found in His Son as revealed in His Word. It’s here that the wisdom of God will get you laughed out of an academic debate. But Scripture makes this point clear in several places:

1 John 2:23 “No one who denies the Son has the Father. Whoever confesses the Son has the Father also.”

1 John 4:15 “Whoever confesses that Jesus is the Son of God, God abides in him, and he in God.”

1 John 5:1 “Everyone who believes that Jesus is the Christ has been born of God, and everyone who loves the Father loves whoever has been born of him.”

2 John 1:9 “Everyone who goes on ahead and does not abide in the teaching of Christ, does not have God. Whoever abides in the teaching has both the Father and the Son.”

In other words, if you have not persuasively turned sinners toward Jesus Christ and the Cross you have not persuaded sinners to God! Even if you can prove God exists — if this is where you end — you have won nothing. When Christians dialogue with atheists/skeptics/agnostics, the discussion must move beyond the mere existence of a god (and the skeptic knows this!).

Attempts to prove the existence of God make it very easy to forget the message of the Cross of Christ. Keeping the Cross central in our conversations with atheists demands that we have a firm handle on the revelation of God that breaks into our hearts and is confirmed by the power of the Holy Spirit.

I’m not supposing we should disengage the debates. Certainly not! The church must continue to engage culture (and atheism is a growing segment of our cultural fabric in America). I’m arguing that a successful debate cannot be defined as the persuading of others of the existence of God. Rather, God is here, He is angry towards sin every day and sinners must bow and repent from their sin. Especially when we enter the philosophical and academic centers of the world God calls us to follow in the footsteps of the Apostle Paul (Acts 17:30-31).

If we have not (by God’s grace) persuaded skeptics to the Cross, neither have we persuaded them to God. The Cross — not Deism — is the goal.

As I finished this post, Jon Bloom posted an excellent comment on another post that fits here. Thanks Jon!

“The person who is certain, and who claims divine warrant for his certainty, belongs now to the infancy of our species.” – Christopher Hitchens.

“I thank you, Father, Lord of heaven and earth, that you have hidden these things from the wise and understanding and revealed them to little children” (Matt 11:25). “Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven” (Matt 18:3). – Jesus

We will always be the infants of our species. Thank you, Tony!

Indeed, Jon. Thank you!
