God is the deity believed by monotheists to be the supreme reality.God is believed variously to be the sole creator,or at least the sustainer,of the universe.The majority of people in the world today claim to believe in a monotheistic God,especially the Abrahamic God of Judaism,Christianity,and Islam,although there are other monotheistic religions.
Theologians have ascribed certain attributes to God,including omniscience,omnipotence,omnipresence,perfect goodness,divine simplicity,and eternal and necessary existence.He has been described as incorporeal,a personal being,the source of all moral obligation,and the greatest conceivable existent.[1] These attributes were all supported to varying degrees by the early Jewish,Christian and Muslim scholars,including St Augustine,[2] Al-Ghazali,[3] and Maimonides.[2]
All the great medieval philosophers developed arguments for the existence of God,[3] attempting to wrestle with the contradictions God's attributes seem to imply.The last few hundred years of philosophy have seen sustained attacks on arguments for God's existence.Against these,theists argue that faith is not a product of reason,but requires risk.
