In Isaiah 28:16, Scripture describes Jesus as the "Chief Cornerstone" of our faith. ... Jesus was and is the only plan of salvation.

And the Apostle Paul reminds the Church of this very fact in Ephesians 2:19-22, Now, therefore, you are no longer strangers and foreigners, but fellow citizens with the saints and members of the household of God, having been built on the foundation of the apostles and prophets, Jesus Christ Himself being the chief cornerstone, in whom the whole building, being fitted together, grows into a holy temple in the Lord, in whom you also are being built together for a dwelling place of God in the Spirit.
