2 Corinthians 3:17

This verse explains the former one. The Holy Spirit (2 Corinthians 3:3; 2 Corinthians 3:6; 2 Corinthians 3:8) is the member of the Trinity who causes a person to understand and believe that Jesus Christ is the fulfillment of the law. Paul here described the Spirit’s function and equated Him with Christ (cf. 2 Corinthians 3:14). Believing in Jesus liberates one from sin, death, and the Mosaic Law but not from obligation to respond obediently to God’s new revelation in Christ, of course. Even though the Spirit is Lord, His presence liberates the believer rather than enslaving him or her (cf. Romans 8:15).
