Why is the concept of Jesus as the cornerstone important for Christians?

The significance of Jesus as the cornerstone cannot be overstated in Christian theology. Ephesians 2:20 illustrates how the church is built upon the foundation of the apostles and prophets, with Jesus Christ Himself as the chief cornerstone. This metaphor conveys that all doctrine and practice within the church must align with Christ, who provides the ultimate structural integrity to the faith community. Furthermore, the metaphor of the cornerstone underscores the truth that Jesus, despite being rejected by men, is foundational to salvation and the believer's identity. Understanding Him as the cornerstone stabilizes believers amidst shifting cultural values and truths, affirming that faith must be anchored in His person and work.
