I’ve been reading Sinners in the Hands of an Angry God and it’s making more sense. You have to read it all and put what Edwards is saying in context. I don’t see the irrationality of it. If your heart is separated from all redeeming mercy it hardens. As a result you will not want heaven. The longer your heart is separated from such grace the harder it becomes and therefore the more wicked. The torment in hell is a restraint to keep those in hell from committing horrendous evil against each other. Because of hardened hearts those in hell will grow accustomed to the environment. They will want to stay there. if they don’t want heaven they don’t have to have it. God’s not going to force them. In the end everyone gets what the want. Those in hell don’t want forgiveness. Jonathan Edwards speaks of this in Sinners in the Hands of an Angry God. Those in hell are wicked with hardened hearts. From their perspective hell isn’t so terrible. Part of the misery of hell is the sad fact that those who are in hell do not even realize how miserable their condition is because they have lost the capacity to appreciate genuine happiness.
From the last page of “Sinners in the Hands of an Angry God”
This acceptable year of the Lord, a day of such great favor to some will doubtless be a day of as remarkable vengeance to others. Men’s hearts harden and their guilt increases apace at such a day as this, if they neglect their souls; and never was there so great danger of such persons being given up to hardness of heart and blindness of mind.
As Edwards states elsewhere n the sermon, Those in hell will hate God and His children.
