Being a Christian is about a relationship, not a religion. I use this cliché all the time, but it is a powerful, true statement. Many people who oppose Christianity ask me and others to prove to them that God exists. This is theoretically impossible. There is no finite way to prove that God exists. To the agnostic or atheist, this seems like a victory against Christianity, but often the same argument can be turned around. How many atheists can prove that God does not exist?
