How do we know that Christ is the cornerstone of our faith?

In the Bible, Christ is repeatedly referred to as the cornerstone, symbolizing His foundational role in our faith. Isaiah 28:16 notes that God has laid a foundation in Zion, a precious cornerstone, underscoring the belief that faith in Christ guarantees stability and security for those who trust in Him. The New Testament also emphasizes this theme, linking Christ's sacrificial death and resurrection as the ultimate fulfillment of these Old Testament prophecies. As believers, we are built upon this rock, which ensures that our faith is grounded in a secure and eternal promise. Ephesians 2:19-22 further explains that we are joined together in Christ, making Him not just our cornerstone but also the very essence of the church's growth and unity.
