Why is it important that Christ's church is portrayed as His bride?

The portrayal of the church as the bride of Christ is crucial because it underscores the depth of the relationship between Christ and His people. This imagery signifies a covenant relationship where Christ, as the husband, is fully committed to the care, love, and sanctification of His church. Ephesians 5:32 calls this a 'great mystery' that refers to Christ and the church. Just as a bride is set apart for her husband, the church is called to be holy and devoted to Christ. This relationship reflects not just kinship, but a profound spiritual union whereby Christ’s redemptive work cleanses and makes the church righteous, alluding to the intimacy and commitment that ensures believers are secure in their salvation.
