What does the Bible say about the church that Christ built?

According to scripture, particularly in Psalm 127, it is affirmed that 'except the Lord build the house, they labor in vain that build it.' This underscores the central truth that Christ Himself builds His church. As promised, He is the cornerstone and the true builder, as declared in Ephesians 2, where believers are described as being built together for a holy temple in the Lord. This church is not just an earthly institution but represents the spiritual dwelling of God among His people, established through Christ's redemptive work on the cross.
