How do we know that Christ is the chief cornerstone?

The affirmation that Christ is the chief cornerstone comes from Ephesians 2:20, where it states that believers are built upon 'the foundation of the apostles and prophets, Jesus Christ himself being the chief cornerstone.' This metaphor underlines how Christ serves as the crucial connection point for the church, uniting diverse believers into one structure. Moreover, in 1 Peter 2:5, believers are described as 'living stones' being built into a spiritual house, indicating that Christ, as the cornerstone, is foundational for spiritual growth and unity. Thus, Christ's position is essential in the architecture of God's redemptive work.
