1 Corinthians 3:11-15

For no one can lay any foundation other than what is being laid, which is Jesus Christ. If anyone builds on the foundation with gold, silver, precious stones, wood, hay, or straw, each builder’s work will be plainly seen, for the Day will make it clear, because it will be revealed by fire. And the fire will test what kind of work each has done. If what someone has built survives, he will receive a reward. If someone’s work is burned up, he will suffer loss. He himself will be saved, but only as through fire.
