Romans 7:23

but. see. different law in my members, warring against the law of my mind, and bringing me into captivity under the law of sin which is in my members. "Different law" -'I see another principle' (Gspd); 'rule of action, or compulsion' (Turner).. 'law' unlike the 'character' ('different'-Greek 'heteros'-something of. different nature) of the law of God that he delights in. 'Differing in kind and aim, not "another" merely' (Alford p. 901)

The 'different law' in this verse isn't the Law of Moses, for that is 'good' (Romans 7:12). Despite Paul's best efforts and his desire to do good (Romans 7:21-22), under the system of Law justification, Paul still observed in himself that sin still was able to carry on. successful campaign against him.

"In my members" -'in the members of my body' (NASV); Romans 6:13.

"Warring against" -'battling against' (Ber); 'In conflict with' (Gspd). In continual dissension and conflict with. (Alford p. 901) Taking the field against (Vincent p. 82)

"the law of my mind" -(Romans 7:22), Paul's agreement with the law of God. Paul sees two authorities saying to him, 'Do this'. And being under. system that demanded flawlessness, sin was able to take him as. prisoner of war.

"under the law of sin" -don't make the mistake of concluding that Paul is saying, 'I couldn't help myself'. (Romans 6:16) Rather, despite the best efforts and intentions, outside of Christ, you will always find yourself in bondage to sin. Sin always wins outside of Christ.

The Ancient World agreed:

'Thus Ovid: "Desire counsels me in one direction, reason in another". "I see and approve the better, but. follow the worse." Epictetus: "He who sins does not what he would, and does what he would not". Seneca: "What, then, is it that, when we would go in one direction, drags us in the other?"
