"Reason can never prove the existence of God."

Next Quote

The main problem with those who deny the existence of God is not intellectual. It is not because of insufficient information, or that God's manifestation of himself in nature has been obscured. The atheists' problem is not that they cannot know God, rather it is they do not want to know him. Man's problem with the existence of God is not an intellectual problem; it is a moral problem." For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men - Rom. 1:18"
