It's all in the Presentation...

12 Let not sin therefore reign in your mortal body, to make you obey its passions. 13 Do not present your members to sin as instruments for unrighteousness, but present yourselves to God as those who have been brought from death to life, and your members to God as instruments for righteousness. 14 For sin will have no dominion over you, since you are not under law but under grace. 15 What then? Are we to sin because we are not under law but under grace? By no means! 16 Do you not know that if you present yourselves to anyone as obedient slaves, you are slaves of the one whom you obey, either of sin, which leads to death, or of obedience, which leads to righteousness? 17 But thanks be to God, that you who were once slaves of sin have become obedient from the heart to the standard of teaching to which you were committed, 18 and, having been set free from sin, have become slaves of righteousness. 19 I am speaking in human terms, because of your natural limitations. For just as you once presented your members as slaves to impurity and to lawlessness leading to more lawlessness, so now present your members as slaves to righteousness leading to sanctification. (Romans 6)

Often in the culinary world there is discussion about "presentation" - that even more than how food smells is how it looks.  The "presentation" Paul talks about here, however, has to do with "presenting", or putting at one's disposal, our lifestyles - giving someone the right to tell us what to do.  We all do it, even if we do not know it at the time.  Without Christ, we were slaves to sin; we had no choice to do what sin says, even though we usually think we are doing what we want; sin uses our selfishness to get its own way.  By the grace of God in Christ, we can now saw "no" to sin and "yes" to God - not in a robotic way, but with a heart of obedience, love, and joy.  When we choose to obey God willingly, accepting the righteousness of Christ on our behalf, God now sanctifies us, "cleaning house" and making our lives "presentable" before His holiness.
