I had a religion professor that tried to prove God by math theory. I loved him. he was awesome. Died of cancer, too soon. I still pray for him all the time. I saw him intervene many times and seriously, no kidding, pluck young people from the jaws of near suicide, because of atheist parents that fucked with their heads. Once we thought the father killed my friend's mother because she was terminally ill, and what she went through afterwards was demonic to my dear friend (who was terrified). And my professor saved her by getting Godly people to intervene and help her, and it gave her hope and got her to move and get away from the demonic father. Miracles happen every day. That is proof enough for me. I do not really need proof because I have faith.
