The more I think on it, the more it bothers me that I heard a professor talking about "proving God's existence" (i.e. Christianity) to an atheist.
It cannot be done. Christianity requires faith. Even the little steps in the life of a Christian are done on faith, not proof. The proof is in the hindsight. Everything I know of that a Christian takes as proof is in fact something very different: It's confirmation.
Proof is a type of knowledge. No one has ever had their knowledge reckoned to them as righteousness. We use proof all the time. Proof is a great thing to have *when both sides agree on the veracity of the proof offered*.
Faith doesn't work on proof. I don't have faith that a thrown ball will land, it can be scientifically proven that it will. Faith is the opposite: It's the belief, acted upon, that the ball will not land. Even a reasonable act of faith is in effect an act of unreason.
When we act in faith, we're stating that we're going to start a process that will completely and disastrously fail without God picking up the slack. We are NOT acting on proof. Not if we're honest about the situation.
Why, then, would we attempt to prove God? If we could prove God, we'd be denying the essential nature of Christianity, namely that it requires faith.
Nevermind the outright foolishness of attempt to outscience people who have placed the entirety of their reason in science.
