How do we know Jesus is the precious cornerstone?

Jesus is portrayed as the 'precious cornerstone' in Scripture, as seen in Isaiah 28:16 and affirmed by Peter in 1 Peter 2:6. This title signifies His central role in building the church and establishing the faith of believers. The apostle Paul clarifies that Christ is the only true foundation upon which the church is built, emphasizing His divine nature as both God and man, who came to redeem sinners. This preciousness is not merely subjective; it is rooted in the divine purpose of God and His exceptional attributes as revealed from both Old and New Testaments.
