R. C. Sproul on “Hell”:
“Perhaps the most frightening aspect of hell is its eternality. People can endure the greatest agony if they know it will ultimately stop. In hell there is no such hope. The Bible clearly teaches that the punishment is eternal. The same word is used for both eternal life and eternal death. Punishment implies pain. Mere annihilation, which some have lobbied for, involves no pain. Jonathan Edwards, in preaching on Revelation 6:15-16 said, “Wicked men will hereafter earnestly wish to be turned to nothing and forever cease to be that they may escape the wrath of God.”
Hell, then, is an eternity before the righteous, ever-burning wrath of God, a suffering torment from which there is no escape and no relief. Understanding this is crucial to our drive to appreciate the work of Christ and to preach His gospel.”
