1 Corinthians 3:12-15

People can build on that foundation using gold, silver, jewels, wood, grass, or straw. But the work that each person does will be clearly seen, because the Day will make it plain. That Day will appear with fire, and the fire will test everyone’s work. If the building they put on the foundation still stands, they will get their reward. But if their building is burned up, they will suffer loss. They will be saved, but it will be like someone escaping from a fire.
