Annihilationism
Annihilationism (also known as extinctionism or destructionism) is a Christian belief that at the Last Judgment those not receiving salvation are destined for total destruction, not everlasting torment.
It is directly related to the doctrine of conditional immortality, the idea that a human soul is not immortal unless it is given eternal life. Annihilationism asserts that God will eventually destroy the wicked, leaving only the righteous to live on in immortality. Some annihilationists (e.g. Seventh-day Adventists) believe God's love is scripturally described as an all-consuming fire and that sinful creatures cannot exist in God's presence. Thus those who elect to reject salvation through their free will are eternally destroyed because of the inherent incompatibility of sin with God's holy character. Seventh-day Adventists and Jehovah's Witnesses posit that eternal hell is a false doctrine of pagan origin.
