"It is not a terrible thing to a wretched soul, when it shall lie roaring perpetually in the flames of hell, and the God of mercy himself shall laugh at them; when...God shall mock them instead of relieving them; when none in heaven or earth can help them but God, and he shall rejoice over them in their calamity." -
Richard Baxter (1615 - 1691)
