"By the Grace God gave me, I laid a foundation like a skilled builder. Someone else is building on it. But everyone needs to be careful about how they build.
Because no one can lay a different foundation than the one that's already there — and that foundation is Jesus Christ.
Now, you can build on that foundation with gold, silver, precious stones — or you can build with wood, hay, and straw. The quality of everyone's work will eventually be exposed. The Day is coming when fire will reveal it. The fire will test what each person has built. If your work survives, you'll receive a reward. If it burns up, you'll suffer the loss — though you yourself will be saved, but barely, like someone escaping through flames."
