Paul has made abundantly clear that those of us in Christ must engage in a kind of battle with ourselves. We have been freed, through our spiritual death and resurrection with Christ, from the power of sin. Our old self has been crucified spiritually in the same way that Christ was crucified spiritually. The result is that sin no longer has any authority over us. We have been set free.
We have not, however, lost our desire to sin. We still want to sin, at times, even knowing how destructive our sin is. Paul has commanded us not to volunteer to sin, not to let it take control of our bodies. Now he puts an even finer point on his command. We must not present our members, any part of our bodies, for sin to use to do unrighteous things.
Notice something about that command: It insists that we have control over what we do with our own bodies. Christ’s death and the power of God’s spirit gives us that control. Those who are saved can only sin by choosing to do so.
Instead, Paul writes, we must present our bodies to God to be used for righteousness. In fact, we should do it on purpose like people who have been brought from death to life. How do we do that? We start by continually reminding ourselves that we have actually and genuinely been brought from death to life. That is who we are now, and that’s the life we are destined to lead
