Why is having Jesus as the cornerstone important for Christians?

The importance of Jesus as the cornerstone cannot be overstated for Christians. He serves as the foundational element upon which the entire structure of faith is built. Ephesians 2:21 describes how the church grows into a holy temple in the Lord, with Christ as the central figure holding it together. This unity in Christ overcomes divisions, such as those between Jews and Gentiles, showcasing His desire for all believers to be reconciled not only to God but also to one another. Furthermore, without Jesus, any attempt at constructing a spiritual life will be unstable and prone to failure, much like a house built on sand rather than a solid rock. Thus, acknowledging and building our lives upon Christ fosters genuine growth, stability, and the assurance of salvation.
