Why is Christ called the head of the corner?

Peter declares in Acts 4:11 that Jesus is the stone which was set at nought and has become the head of the corner. This terminology signifies that Christ is the cornerstone of the Church and God's redemptive plan. Just as a cornerstone is vital for the strength and stability of a building, Jesus is foundational to the faith of believers. Without acknowledging and accepting Christ's role as the cornerstone, one cannot experience genuine salvation and communion with God. This concept invites us to explore how our faith is built upon Him and the importance of Christ as the central figure in our lives.
