How do we know Jesus is the cornerstone of our faith?

The notion of Jesus as the cornerstone is rooted in prophecy and affirmed in the New Testament. Isaiah 28:16 speaks of Him as a precious cornerstone, while the New Testament reinforces this by stating in Ephesians 2:20 that the church is built upon the foundation of the apostles and prophets, with Christ Jesus Himself as the chief cornerstone. This cornerstone imagery underscores the reliability and stability that believers find in Christ, contrasting with the shifting sands of human wisdom and understanding.
