I'm answering the question, "Is there any evidence that can prove Christianity?" on the Alethia forum:
I don't think that we can "prove" our worldview to others, even as they cannot to us. Most apologetics are only assuring to those who already believe, comforting them that what they believe isn't foolish, but based on reasonable evidence.
However, I don't think "reason", of whatever flavor, convinces anyone of anything that goes against their firmly-held beliefs.
This doesn't mean that a person can't be converted. However, the "evidence" that convinces them would be personal, not intellectual. There are only two things that convinces a person of the truth of Jesus:
a. A life that is sincerely and lovingly lived in Jesus, in close relation with those who do not believe. Over time, they may see that belief in Jesus is the most reasonable way to live, not because of proofs, but because of a sincere and compassionate heart that makes other people's lives better.
b. A personal experience with the Lord. Jesus and the Father are persons, not intellectual property. If I wanted to convince you of the existence of my friend Bill, I wouldn't argue about it, I'd just have you shake his hand. Often the best evidence is the Lord just "shaking the hand" of the unbeliever. Thus, my most common prayer for those who don't believe in the Lord is that the Lord would reveal Himself to them.
I think there is a good place for apologetics, but I don't find it as useful as I did in my early Christian years.
