Jesus Christ stands as the Chief Cornerstone of our spiritual foundation, the central and most vital part upon which the entire structure of the church rests. In Ephesians 2:20, Paul emphasizes that He is the cornerstone, the primary stone at the foundation's extreme corner, bearing the load of intersecting walls and supporting the whole edifice. This imagery reflects the massive, precisely cut stones of the Temple, which, due to their weight and interlocking design, needed no mortar to remain immovable. As the Chief Cornerstone, He upholds and aligns the spiritual Temple, ensuring its stability against any force. Paul further confirms in I Corinthians 3:11 that no other foundation can be laid than that which is in Him, underscoring that any deviation from His true gospel results in a flawed foundation unable to support what is built upon it. His teaching is the touchstone for all spiritual truth, anchoring and undergirding every other element of God's Word. In Isaiah 28:16, He is described as a tried stone, tested and found perfect, or a trying stone, against which others are measured. He is also a precious cornerstone, rare and excellent, of ultimate value in every aspect of His character and works. As a sure foundation, He is unyielding and immovable, the ultimate base upon which faith can rest without fear of collapse or shame, as reiterated in I Peter 2:6. Psalm 118:22-23 portrays Him as the head of the corner, laid by God to provide salvation, making possible the marvelous day of deliverance through His unique and indispensable role. Finally, in Deuteronomy 30:20, He is declared as our life and the length of our days, offering eternal extension through His strength as the Chief Cornerstone upon which we must stand to inherit the promises of salvation.

Christ is the rock upon which He builds His church, not Peter, who is likened to a pebble or small stone. He declares that He would establish His church on the boulder, emphasizing that He Himself is the chief cornerstone, the foundation upon which the church stands. Through this, it is clear that He, not a mere man, is the enduring strength that ensures the church will prevail.

Jesus Christ is not merely a foundation or a cornerstone, but He is the Chief Cornerstone upon which the prophets and apostles have built. We are to use the teachings of the apostles and prophets in God's Word to develop the righteousness of Christ with God's help. Our works require more than physical effort or service in God's church; they demand the righteousness of Jesus Christ as the foundation of our lives. All the wealth and gifts of the world are not pleasing to God and will not endure unless they are built upon this foundation of righteousness, upon Jesus Christ. As the temple of God, if we submit to Him, He will build our foundation on Jesus Christ, creating an everlasting foundation of righteousness that cannot be destroyed.
