Edwards believed that the saints will rejoice over the torments of the damned only in the sense that they will be rejoicing at the glory of God’s justice not the evil and suffering in and of itself. They are not sadistic or bloodthirsty.
Why Saints in Glory Will Rejoice to See the Torments of the Damned
By Jonathan Edwards (1703–1758)
[Sermon: The end of the Wicked contemplated by the Righteous.]
NEGATIVELY: it will not be because the saints in heaven are the subjects of any ill disposition; but, on the contrary, this rejoicing of theirs will be the fruit of an amiable and excellent disposition: it will be the fruit of a perfect holiness and conformity to Christ, the holy Lamb of God. The devil delights in the misery of men from cruelty, and from envy and revenge, and because he delights in misery, for its own sake, from a malicious disposition.
But it will be from exceedingly different principles, and for quite other reasons, that the just damnation of the wicked will be an occasion of rejoicing to the saints in glory. It will not be because they delight in seeing the misery of others absolutely considered. The damned suffering divine vengeance will be no occasion of joy to the saints merely as it is the misery of others, or because it is pleasant to them to behold the misery of others merely for its own sake… It will be an occasion of their rejoicing, as the glory of God will appear in it.
