Christianity is a very historical religion - it makes specific claims that are open to testing.

I have a good Muslim friend who comes over to my house. Good guy; reads the Qur'an in Arabic. He comes over to my house and we talk about faith and we talk about things we have in common, but I can't shy away from the differences that we have. So I talk about why I'm not a Muslim and about the evidence that exists that show Christianity is true.

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.

Doubts can produce positive side-effects - if you work toward resolving them.

I’ve seen far too many Christians who are more than willing to travel halfway around the world to volunteer for a week in an orphanage, but who cannot bring themselves to take the personal risk of sharing Jesus with the co-worker who sits day after day in the cubicle right next to them.

Nobody is beyond the reach of the Gospel.

I don't feel like I was argued into the faith, but I feel like the evidence knocked down a succession of objections and issues and questions and doubts that I had, that sort of cleared the pathway for me to come to the faith.
