Let Not Sin Reign in Your Mortal Bodies That You Should Obey It!

Romans 6

SANCTIFICATION

12 Let not sin (the sin nature) therefore reign (rule) in your mortal body (showing that the sin nature can once again rule in the heart and life of the Believer, if the Believer doesn’t constantly look to Christ and the Cross; the “mortal body” is neutral, which means it can be used for Righteousness or unrighteousness), that you should obey it in the lusts thereof (ungodly lusts are carried out through the mortal body, if Faith is not maintained in the Cross [1 Cor. 1:17–18]).
13 Neither yield you your members (of your mortal body) as instruments of unrighteousness unto sin (the sin nature): but yield yourselves unto God (we are to yield ourselves to Christ and the Cross; that alone guarantees victory over the sin nature), as those who are alive from the dead (we have been raised with Christ in “Newness of Life”), and your members as instruments of Righteousness unto God (this can be done only by virtue of the Cross and our Faith in that Finished Work, and Faith which continues in that Finished Work from day-to-day [Lk. 9:23–24]).
14 For sin shall not have dominion over you (the sin nature will not have dominion over us if we as Believers continue to exercise Faith in the Cross of Christ; otherwise, the sin nature most definitely will have dominion over the Believer): for you are not under the Law (means that if we try to live this life by any type of law, no matter how good that law might be in its own right, we will conclude by the sin nature having dominion over us), but under Grace (the Grace of God flows to the Believer on an unending basis only as long as the Believer exercises Faith in Christ and what He did at the Cross; Grace is merely the Goodness of God exercised by and through the Holy Spirit, and given to undeserving Saints).
15 What then? (This presents Paul going back to the first question he asked in this Chapter.) shall we sin, because we are not under the Law, but under Grace? (If we think such a thing, then we’re completely misunderstanding Grace. The Grace of God gives us the liberty to live a Holy life, which we do through Faith in Christ and the Cross, and not license to sin as some think.) God forbid (every true Believer hates sin; so the idea of living under its dominion is abhorrent to say the least!).
16 Know you not, that to whom you yield yourselves servants to obey, his servants you are to whom you obey (the Believer is either a slave to Christ, for that’s what the word “servant” means, or else a slave to sin, which he will be if he doesn’t keep his Faith in Christ and the Cross); whether of sin unto death (once again allow us to state the fact that if the Believer attempts to live for God by any method other than Faith in the Finished Work of Christ, the Believer will fail, no matter how hard he otherwise tries), or of obedience unto Righteousness? (The Believer is required to obey the Word of the Lord. He cannot do that within his own strength, but only by understanding that he receives all things through what Christ did at the Cross and his continued Faith in that Finished Work, even on a daily basis. Then the Holy Spirit, Who Alone can make us what we ought to be, can accomplish His work within our lives.)
