Why is the foundation of the church significant?

In the sermon, it is highlighted that just as a building requires a strong foundation, the church is established on the foundation of Jesus Christ. He is referred to as the chief cornerstone, which ensures that the church will be built securely. This not only signifies the importance of Christ’s redemptive work but also marks the church's identity as His body on earth. As elaborated in Ephesians 2:20, the church is built upon the foundation of the apostles and prophets, Christ Jesus Himself being the cornerstone. This view establishes that the church’s ultimate purpose is to glorify God, and it teaches that the work done by believers must be rooted in Christ’s righteousness and grace, ensuring that the church stands resilient against all adversities.
