Look, if no murderer hath eternal life, how can he have eternal suffering?First of all, in order for a person to experience "eternal torment" one would have to be existing. This is why it is important to understand the story of the rich man and Lazarus. It states that both men died, yet their spirits were in Hades, conscious and aware. The rich man could see and speak with Abraham's spirit. And the rich man could experience the torment of the flame.The state of death is conscious existence, not nonexistence.
Genesis 2:7 KJV plainly says the soul exists as a consequence of the union of the Body and the Breath of Life. It can no longer continue to exist after these two separate any more than the joint can exist when the bones and marrow separate, says Hebrews 4:12 KJV.
