Romans 6:13

‘Nor go on presenting your members to sin as instruments of unrighteousness; but present yourselves to God, as alive from the dead, and your members as instruments of righteousness unto God.'

So we are no longer to ‘go on presenting' our ‘members' (the parts of our body) to sin as instruments of unrighteousness. That was part of the old life. We must control the eye, the ear, the mouth, the hand, the foot, the mind, the will. If they cause us to offend we must metaphorically ‘cut them off and cast them from us' (Mark 9:43). Rather we are to present ourselves to God, as alive from the dead, and to present our members as instruments of righteousness to God. We must recognise new ownership. In contrast with sin, which took us over as a tyrant, God waits for our personal response. God is not a tyrant. There is thus to be a positive presenting of ourselves to God as those who are now alive in Christ.

And along with this will go the presentation of our members to Him as instruments, no longer of unrighteousness, but of righteousness. There is an encouragement here to present each part of ourselves to God part by part. First ourselves, and then each part of us specifically (eyes, ears, mouth, hand and foot). Note how ‘lived out righteousness' has now become the practical outworking of our having been ‘reckoned as righteous'. The righteousness of God, having made us acceptable to God, is to produce righteousness within us, although it should be noted that Paul nowhere directly makes this application when speaking of ‘the righteousness of God', for from his point of view ‘the righteousness of God' is a righteousness which can be accounted to us. But because He has accounted us as righteous through His righteousness, righteousness in God's eyes is to be our business.
