Omnipotence is the quality of having unlimited power. Monotheistic religions generally attribute omnipotence only to the deity of their faith. In the monotheistic religious philosophy of Abrahamic religions, omnipotence is often listed as one of God's characteristics, along with omniscience, omnipresence, and omnibenevolence. The presence of all these properties in a single entity has given rise to considerable theological debate, prominently including the problem of evil, the question of why such a deity would permit the existence of evil. It is accepted in philosophy and science that omnipotence can never be effectively understood.
