A.T. Robertson Commentary 1 Corinthians 15:56

"The sting of death is sin; and the power of sin is the law:" — 1 Corinthians 15:56 (ASV)

The power of sin (η δυναμις της αμαρτιας). See Ro 4:15; 5:20; 6:14; 7; Galatians 2:16; 3:1-5:4 for Paul's ideas here briefly expressed. In man's unrenewed state he cannot obey God's holy law.
