1 Corinthians 3:10 (KJV 1900)
10 According to the grace of God which is given unto me, as a wise masterbuilder, I have laid the foundation, and another buildeth thereon. But let every man take heed how he buildeth thereupon.
Paul shifts his metaphor from working in the field to constructing a building. When Paul came to Corinth (See Acts 18:1-11), he planted the seed of the cross of Christ, and then through eighteen months of teaching, he laid the foundation for the Corinthian’s faith. He was able to do his work only according to the grace of God.
Paul came humbly to Corinth (2:3) and declared only the testimony of God, that is, the cross of Christ. In doing so, and in only preaching that particular message, he was the wise master builder of the church. From the work of Paul, by God’s grace, others had the task of continuing his work. But he warned them to take heed how they build.
Where is the Corinthian church today? It is gone. They did not take heed to the apostle’s teaching and lost their way. They became unwise builders at some point. The message of the cross got watered down with other teachings that eventually crept into the church, which was why Paul warned them.
We should take heed of everything we teach and how we build–ensuring it’s accomplishment through careful study of the Word of God.
