What To Do About Sin
The Greek word used here, thanatos, refers not only to spiritual or physical mortality, but to separation from God.
Death is the normal consequence of sin (which is disobeying God); righteousness is the normal consequence of obeying God and living for Him.
As we noted above, when Paul talks about the new power over sin that is given to a Christian, he does not say that there will be no sin in the Christian’s life, but he simply tells the believers not to let sin “reign” in their bodies nor to “present” their members to sin (Rom. 6:12–13). He does not say that they will not sin but says that sin will not dominate or “have … dominion” over them (Rom. 6:14). The very fact that he issues these directions shows his realization that sin will continue to be present in the lives of believers throughout their time on earth. Even James the brother of our Lord could say, “We all stumble in many ways” (James 3:2), and if James can say this, then we certainly should be willing to say it as well. Finally, in the same letter in which John declares so frequently that a child of God will not continue in a pattern of sinful behavior, he also says clearly, “If we say we have no sin, we deceive ourselves, and the truth is not in us” (1 John 1:8). Here John explicitly excludes the possibility of being completely free from sin in our lives. In fact, he says that anyone who claims to be free from sin is simply deceiving himself, and the truth is not in him.
Moreover, as Christians grow in maturity, the kinds of sin that remain in their lives are often not so much sins of words or deeds that are outwardly noticeable to others, but inward sins of attitudes and motives of the heart—desires such as pride and selfishness, lack of courage or faith, laziness, lack of zeal in loving God with our whole hearts and our neighbors as ourselves, and failure to fully trust God for all that he promises in every situation. These are real sins! They show how far short we fall of the moral perfection of Christ.
pattern of teaching Refers to the gospel message and its ethical implications. Paul emphasizes obedience because it functions as the only tangible expression of faith.
