Romans 6:13

neither present your members unto sin as instruments of unrighteousness; but present yourselves unto God, as alive from the dead, and your members as instruments of righteousness unto God.

NOTE: The body is. "neutral" instrument. The sin problem doesn't arise in the body, is comes from the 'heart/mind' (Mark 7:20). 'Neither present', Paul is not taking to the body, he is talking to the person inside the body! These verses strongly contradict the view that seeks to convert 'sin' into. mere physical addiction or problem caused by genetics.

'Present' -'do not go on presenting' (NASV); 'Stop presenting your members or do not have the habit of doing so' (Robertson p. 363) 'Do not offer any part of your bodies to Sin' (TCNT)

'Members' -'any part of your body' (Mon) (Proverbs 6:16)

'Instruments' -3696. hoplon hop'-lon; probably from. primary hepo (to be busy about); an implement or utensil or tool (literally or figuratively, especially offensive for war): -armour, instrument, weapon.

Again, 'free-will' is stressed. Paul says, stop allowing your body to be used in the service of sin. Stop it and stop it now! Rather, allow your body to be used in the service of God. Let your mouth spread the gospel instead of gossip, let your hands help instead of hurt, let your feet run to assist instead of running away, let your eyes behold truth instead of trash. Away with the weak excuse of 'I'm just too weak and. can't help myself'.
