What is the significance of Jesus as the cornerstone of the church?

In Ephesians 2, Paul writes about Christ as the cornerstone, which is foundational for the entire edifice of the church. The cornerstone is a vital stone that ensures the integrity of the structure. Jesus being the cornerstone indicates that He is the essential element that supports and holds the church together. All members of the church, described as living stones, are built upon this foundation, ensuring unity and stability. This imagery emphasizes that the church's existence and purpose derive from Christ alone, validating that its strength lies not in human effort or physical buildings but in the redemptive work of Him who is the chief cornerstone. Through being united in Him, the church flourishes as a dwelling place for God's Spirit.
