What does the Bible say about Christ as the foundation of the church?

The Bible teaches that Christ is the cornerstone and foundation upon which the church is built. In Exodus 30, the silver used as ransom money symbolizes Christ's sacrifice, which established the foundation of redemption for His people. He accomplished the redemption necessary for sinners to be counted as part of His church. Just as the Israelites were reminded of their redemption through the ransom money, Christians are reminded that their acceptance before God is solely based on Christ's atonement.
