How do we know the church was purchased by Christ?

Acts 20:28 reveals that the church of God was purchased with Christ's own blood, highlighting the magnitude of His sacrifice. This purchase is not ongoing; it is a completed act, affirming that redemption is solely the work of God and not of man. Theological analysis shows that the term 'purchased' implies that Christ has made His people a special possession, drawing them around Himself. The beauty of this concept is that it signifies not only ownership but also the intimate relationship established between Christ and His church because He willingly gave Himself for it.
