“Theism: A term which refers to the belief in the existence of a divine being, especially in the existence of a single God, who is thought to be personal and who is the Creator of the universe. Theism involves the idea of divine revelation, and consequently is contrasted with deism, the rational belief in divinity independent of faith in a revealed truth.”
