Are the lost annihilated after death according to the Bible?
No, the lost are not annihilated after death. The Bible teaches they are resurrected to a life separated from God, the second death, yet they continue through all eternity, experiencing suffering, regret, and feeling. This directly contradicts the idea that they cease to exist.
Les explains that resurrection is not just being brought back to life; it is God's unique, sovereign act of bringing a dead human being back to a life of eternity. He stresses that when God breathed into man the breath of life, man became a living soul, making man immortal in the area of the soul and spirit. The body is not immortal, but the soul/spirit is. Revelation speaks of the resurrection of the just to a life of immortality in God's presence. The lost, however, are resurrected to a life separated from God, or the second death, but they still continue on through all eternity. Les notes that some groups teach that when a lost person dies they are annihilated, but that does not line up with Scripture. Instead, the lost will suffer, experience regret, and experience feeling throughout all the eons of eternity. Christ was the first person to ever experience resurrection, called the first fruits of them that slept.
