What does the Bible say about the cornerstone of faith?

In 1 Peter 2:6-7, Jesus is identified as the chief cornerstone, a vital piece that defines the integrity of the spiritual house being built by believers. Just as the cornerstone in physical construction holds entire buildings together, Christ holds together the faith and lives of His followers. Peter draws from Old Testament texts, such as Psalm 118, to emphasize that Jesus, though rejected by many, is precious and essential to the faith. This imagery illustrates how Christ as the cornerstone is not just foundational but also the most significant aspect in the structure of salvation and spiritual life.
