1 Corinthians 3:12-15

But if any man buildeth on the foundation gold, silver, costly stones, wood, hay, stubble; each man’s work shall be made manifest: for the day shall declare it, because it is revealed in fire; and the fire itself shall prove each man’s work of what sort it is. If any man’s work shall abide which he built thereon, he shall receive a reward. If any man’s work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as through fire.
