Why is Christ called 'the precious cornerstone'?

The title 'precious cornerstone' reflects the invaluable worth of Christ to believers, as articulated in 1 Peter 2:6. He is not only essential for the structure of faith but He is also of great value due to His redemptive work and nature. Just like the cornerstone is crucial for the integrity of a building, Jesus is critical for the wholeness and purpose of a believer’s life. His blood, which is referred to as precious in 1 Peter 1:18-19, signifies the high cost of our redemption. Thus, the preciousness of Christ conveys both His intrinsic worth and the great love demonstrated through His sacrifice.
