Honest Question to Atheists - Best Argument?

[Rhondazvous]

Has there ever been a Christian argument, or something a Christian said, that made you, for even a split second, question whether your current atheistic stance is right?

Even if the argument turned out to be completely fabricated or disprovable, did it at the very least draw you closer to believing the Bible is God's Word and all that such a belief entails?

If not, has there ever been an argument that you didn't know how to answer, or that surprised you  against your expectations?

Not looking for "All Christian arguments are idiotic" replies. This is an honest question.

I was a Christian for 25 years and have that much indoctrination that I've had to sort through. It all made sense when I was a Christian.

As you asked, I won't dismiss your question as idiotic, however, I will take note that it assumes that Christianity and atheism are the only parameters. That's a question I had to deal with. Is atheism the only alternative to Christianity and If I can't embrace atheism wholesale does that enjoin me to return to Christianity?

As I have said elsewhere, one cannot prove the existence of the Christian god with arguments. If god doesn't actually show himself, for a Christian to come up with an irrefutable argument for his existence is like making potato salad with every ingredient except potatoes. The sine qua non of god is god.
