How should preachers build upon the foundation of Christ?

According to 1 Corinthians 3:10-11, preachers are called to build upon the foundation of Christ using materials that will endure. This means that the focus of preaching must be centered on the person and work of Jesus Christ. It is not merely about presenting moral teachings or religious advice but rather declaring the gospel, which transforms lives and edifies the church. By ensuring that the message is consistently about Christ and His grace, preachers contribute to the spiritual growth of the church and the glory of God.
