How do we know the church belongs to Christ?

The church belongs to Christ as stated in Acts 20:28, where it is revealed that He purchased the church with His own blood. This act emphasizes the immense value God places on His people. The sacrificial death of Christ not only redeems individuals but also establishes them as part of His church, highlighting the intimate relationship between Christ and His believers. As members of the body of Christ, believers are therefore called to live in obedience and dedication to His purpose within the church.
