The foundation that has already been laid is Jesus Christ, and no one can lay down any other foundation.
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 Judgmentn 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.
