1 Corinthians 3:13-15

13 each one's work will become clear; for the Day will declare it, because it will be revealed by fire; and the fire will test each one's work, of what sort it is.
14 If anyone's work which he has built on it endures, he will receive a reward.
15 If anyone's work is burned, he will suffer loss; but he himself will be saved, yet so as through fire.
