Many people believe in the omniscience or all-knowing power of God.
Omniscience comes from the Latin omnis meaning "all" and scientia meaning "knowledge." Omniscience is a state of possessing all the knowledge there is — pretty impressive. In a religious sense, people believe in a higher being that has omniscience. In literature, omniscience can refer to the perspective of a narrator who is all-knowing or has the ability to see into the minds of all his characters.
