What does the Bible say about Jesus being the foundation of the church?

1 Corinthians 3:11 states, "For other foundation can no man lay than that is laid, which is Jesus Christ." This verse emphasizes that Jesus alone is the cornerstone upon which the church is built. Throughout scripture, the significance of Christ as the foundation is further established, with verses from the Old Testament, such as Psalm 118:22 and Isaiah 28:16, affirming this truth. The unity of the church, consisting of all believers, is built upon Christ, illustrating that our faith and hope must solely rest in Him.
