It was the evidence from science and history that prompted me to abandon my atheism and become a Christian.
In short, I didn't become a Christian because God promised I would have an even happier life than I had as an atheist. He never promised any such thing. Indeed, following him would inevitably bring divine demotions in the eyes of the world. Rather, I became a Christian because the evidence was so compelling that Jesus really is the one-and-only Son of God who proved his divinity by rising from the dead. That meant following him was the most rational and logical step I could possibly take.
The Internet has helped atheists and agnostics coalesce as never before.
I'm noticing an exciting trend around the country: a resurgence of interest in Christian apologetics (the defense of the faith). This is a reaction to the current attacks on the essentials of Christianity that are coming from militant atheists, radical professors, and Internet gadflies.
