1 Corinthians 3:11-15

For no one can lay any foundation other than what has been laid down. That foundation is Jesus Christ. If anyone builds on the foundation with gold, silver, costly stones, wood, hay, or straw, each one’s work will become obvious. For the day will disclose it, because it will be revealed by fire; the fire will test the quality of each one’s work. If anyone’s work that he has built survives, he will receive a reward. If anyone’s work is burned up, he will experience loss, but he himself will be saved  — but only as through fire.
