If any man’s work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire. 1 Corinthians 3:15
When death approaches to life, and darkness to light, and the corruptible to the incorruptible, the inferior is done away with and reduced to non-existence, and the thing purged is benefited, just as the dross is purged from gold by fire. In the same way in the long circuits of time, when the evil of nature which is now mingled and implanted in them has been taken away, whensoever the restoration to their old condition of the things that now lie in wickedness takes place, there will be a unanimous thanksgiving from the whole creation, both of those who have been punished in the purification and of those who have not at all needed purification.
