To believe in eternal conscious torment - by Oscar Baker, but I shortened it a bit.
1- You would have to agree that sin could never then be eradicated. As long as a sinner is alive, there is sin in the universe. God's goal of a sinless universe could, therefore, never be reached. If sinners live eternally in the universe, Satan's statement of "Thou shall not surely die". would be truth and not a lie.
2- God would have to create a body that would be resistant to fire. This body would have to be immortal. So, everyone, the saved and unsaved would have an immortal body.
3-The word says that death and Hell will be tossed into the lake of fire. However, since the unsaved is immortal, how would you dispose of him?
4- If men must spend eternity finishing the penalty for sin, then Christ did not die for the ungodly
Salvation is a matter of life and death, not happiness and misery
