1 Corinthians 3:12-15

But if people build on that foundation, using gold, silver, jewels, wood, grass, or straw, their work will be clearly seen, because the Day of Judgment will make it visible. That Day will appear with fire, and the fire will test everyone’s work to show what sort of work it was. If the building that has been put on the foundation still stands, the builder will get a reward. But if the building is burned up, the builder will suffer loss. The builder will be saved, but it will be as one who escaped from a fire.
