Why is the concept of Christ as the chief cornerstone important for Christians?

The significance of Christ as the chief cornerstone cannot be overstated; it assures Christians that our faith is built on a solid foundation, ensuring that our relationship with God is secure. In Ephesians 2:19, believers are described as fellow citizens with saints, no longer strangers, due to their positioning in Christ. This emphasizes the transformation brought about by faith in Him. As the cornerstone, Jesus establishes the parameters of our faith, ensuring stability amidst trials and uncertainties in life, thus making Him indispensable to every believer's walk with God.
