An all-powerful God exists. An all-good God exists. Consider being approached by criminals who demand payments or otherwise harm will come to you, when prior to this demnad you felt no need for protection from such unseen evils. This is clearly extortion, the same as we Creators view the theory of a God who demands our love and praise or otherwise we are doomed to burn in eternal hellfire, when prior to hearing of this demand we felt no need for protection from such an unseen evil. Infinite punishment for finite sins clearly does not fit the bill of an all-good God.
Faith is defined as a firm belief in something for which there is no proof.
Isn't it funny that the Christians say that when good things happen in our lives it is God's will, but when bad things happen, well, He just works in mysterious ways. As an intelligent person, I would never believe unsubstantiated claims that there were leprechauns or elves in a forest if I never saw them for myself. I certainly have never had any God speak to me or give me any visions or prophecies, and I've never seen a single miracle. Were there a God who did so, then beyond any doubt I would love and praise Him beyond measure. But as it stands, per Christianity, I am a heathen, a lost soul, headed straight to searing brimstone.
