Unending Existence, or ETERNITY, is an infinite period of time without beginning or end. It is often used to refer to the afterlife, or a spiritual realm that exists beyond physical reality. In Christianity, it is believed that those who accept Jesus Christ as their savior will spend ETERNITY in Heaven. In other religions, such as Hinduism and Buddhism, ETERNITY is seen as a cycle of reincarnation. In either case, ETERNITY is an unending existence that transcends physical reality.
