9. For we are partners working together for God, and you are God's field.You are also God's building.
10. Using the gift that God gave me, I did the work of an expert builder and laid the foundation, and someone else is building on it. But each one must be careful how he builds.
11. For God has already placed Jesus Christ as the one and only foundation, and no other foundation can be laid.
12. Some will use gold or silver or precious stones in building on the foundation; others will use wood or grass or straw.
13. And the quality of each person's work will be seen when the Day of Christ exposes it. For on that Day fire will reveal everyone's work; the fire will test it and show its real quality.
