Chapter 21 — Part I — Article XII (Of Life Everlasting)

Section 383. Q. But what will be the lot of unbelievers and transgressors? A. They will be given over to everlasting death--that is, to everlasting fire, to everlasting torment, with the devils. Whosoever was not found written in the book of life was cast into the lake of fire. Rev. xx. 15. And, That is the second death. Rev. xx. 14. Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels. Matt. xxv. 41. And these shall go away into everlasting punishment, but the righteous into life eternal. Matt. xxv 46. It is better for thee to enter into the kingdom of God with one eye, than having two eyes to be cast into hell fire: where their worm dieth not, and the fire is not quenched. Mark ix. 47, 48.
