To me it is hard to understand. How does not being under law prevent sin from having dominion over a person?
Brother, when the "law" referred to keeps people in "sin" by making them disobey God! No longer being under that human "law" in Judaism allows people to obey God, who does take away sin, as we practice the correct use of God's name. Doing what God asked instead of the human "law" of Judaism that prevents people from obeying God. Those who still follow the human "law" of Judaism, instead of obeying God by not uttering God's name at all, disobey to learn to use God's name correctly and gain "dominion" over the sin that is prevalent among the disobedient.
Jesus replied, “You hypocrites! Isaiah was right when he prophesied about you, for he wrote, ‘These people honor me with their lips, but their hearts are far from me. Their worship is a farce, for
they teach man-made ideas as commandments from God.’ For you ignore God’s
law/commandment and substitute your own tradition.” Then he said, “You skillfully sidestep God’s
law(nomos)/commandment(entolé) in order to hold on to your own tradition. For instance, Moses gave you this
law(nomos)/commandment(entolé) from God: ‘Honor your father and mother,’ and ‘Anyone who speaks disrespectfully of father or mother must be put to death.’ But you say it is all right for people to say to their parents, ‘Sorry, I can’t help you. For I have vowed to give to God what I would have given to you.’ In this way, you let them disregard their needy parents. And so you cancel the word of God in order to hand down your own tradition. And
this is only one example among many others.” (
Mark 7:6-13 NLT fixed)
Sin’s ability to adversely affect our future relationship with God is destroyed because we are not currently under law, but under grace. We are free now to serve God in the newness of the Spirit, and not the oldness of the letter.
Paul is not referring to the Holy Spirit as the translators force by adding the word holy before the word Spirit not found in the original. Jesus is the model "Spirit" to follow Paul speaks of in obedience to the Ten Commandments when compared to Judaism's sabotage to not remove the sin that the Ten Commandments were written in "letters" in stone to remove. Judaism prevented the removal of sin in God's "order" through the prophet Moses by substituting God's Ten Commandments with their own human "law", that Jesus has freed us from in Paul's message and not from God's "order" through the prophet Moses like our sinful human nature wants. For example, Judaism is cursed because instead of obeying God by learning to use His name properly, Judaism replaced God's Third Commandment for those who would be the sons of Sarah, with their own human "law" to not utter God's name at all in the resulting sons of Hagar, thus disobeying to learn to use God's name properly. Like them, the human excuse today for disobeying the Ten Commandments is to say that we now follow the Holy Spirit, in a misunderstanding of Paul's use of the word "Spirit" in the following passage, where Jesus is the model Spirit to follow in obedience to the Ten Commandments, instead of Judaism's human tradition replacing the letters written in stone. Paul is not referring to the Holy Spirit as a substitute to disobey Jesus’ Eleven Commandments, forced by the translators by adding the word holy before the word “Spirit”, when the word holy is not found in the original. Paul tells us the word "Spirit" is Jesus and not the Holy Spirit by saying in the passage: "the Lord—who is the Spirit—makes us more and more like him as we are changed into his glorious image". Following Jesus as the model "Spirit" who obeyed the Ten Commandments as the example for the sons of Sarah, rather than Judaism's replacement of human law in the resulting sons of Hagar, will result in obeying "all" the Ten Commandments that Judaism did not obey. Judaism, like us today, did not obey the Ten Commandments by instead replacing what God asked with human traditions, like us replacing the Sabbath with Sunday. People use the word "Spirit" in this passage to refer to the Holy Spirit instead of Jesus, because they want to do away with the Ten Commandments when that is not Paul's message but what our sinful human nature wants. Paul's message wants us to obey "all" the Ten Commandments by having us follow Jesus as the model "Spirit" in the following passage instead of Judaism's tradition of not obeying "all" the Ten Commandments when they replaced the Ten Commandments with human "law".
We are confident of all this because of our great trust in God through Christ (as the model "Spirit" to follow). It is not that we think we are qualified to do anything on our own (like excusing our disobedience of the Ten Commandments as coming from the Holy Spirit). Our qualification comes from God (sending us Jesus as the model "Spirit" to follow). He has enabled us to be ministers of his new covenant (Jesus as the model "Spirit" to follow). This is a covenant not of the letter (Ten Commandments), but of the Spirit (Jesus as the model "Spirit" to follow and not the Holy Spirit used as an excuse to disobey the Ten Commandments when Jesus obeyed them). The letter ends in death (sabotaged by Judaism to not remove sin); but the Spirit (Jesus as the model "Spirit" to follow) gives life (the removal of sin). The old way (God's "order" by the prophet Moses), with letters etched in stone (Ten Commandments), led to death (sabotaged by Judaism to not remove sin), though it began with such glory (leading to righteousness) that the people of Israel could not bear to look at Moses’ face. For his face shone with the glory of God (which is His righteousness expressed in the Ten Commandments), even though the brightness was already fading away (Judaism's unwillingness to obey "all" the Ten Commandments). Shouldn’t we expect far greater glory under the new way (Jesus as the model "Spirit" to follow), now that the Holy (added by the translators) Spirit (not the Holy Spirit but Jesus as the model "Spirit" to follow) gives life? If the old way (written letters etched in stone), which brings condemnation (Judaism not fully obeying "all" the Ten Commandments by replacing them with human "law"), was glorious (leading to righteousness), how much more glorious (leading to righteousness) is the new way (Jesus as the model "Spirit" to follow), which makes us right with God (removes sin)! In fact, that first glory (which led to righteousness) was not glorious at all compared with the overwhelming glory (leading to righteousness) of the new way (Jesus as the model "Spirit" to follow). So if the old way (written letters etched in stone), which has been replaced, was glorious (led to righteousness), how much more glorious (leading to righteousness) is the new (Jesus as the model "Spirit" to follow), which remains forever! Since this new way (of following the model "Spirit" of Jesus, rather than Judaism's human "law") gives us such confidence, we can be very bold (learning to use God's name properly, which Judaism does not). We are not like Moses, who put a veil over his face so the people of Israel would not see the glory (of God's righteousness), even though it was destined to fade away (by Judaism's unwillingness to obey all the Ten Commandments). But the people’s minds were hardened (to not obey all the Ten Commandments), and to this day whenever the old covenant is being read, the same veil covers their minds so they cannot understand the truth (of the failure of replacing God's Commandments with their own human law). And this veil can be removed only by believing in Christ (as the model "Spirit" to follow). Yes, even today when they read Moses’ writings, their hearts are covered with that veil, and they do not understand (they failed to obey all of God's Ten Commandments by substituting them with human "law"). But whenever someone turns to the Lord, the veil is taken away. For the Lord is the Spirit (Jesus is the model "Spirit" to follow who obeyed the Ten Commandments as our example and Paul is not referring to the Holy Spirit as an excuse to disobey the Ten Commandments), and wherever the Spirit of the Lord is, there is freedom (from sin and not from God's Ten Commandments). So all of us who have had that veil removed can see and reflect the glory of the Lord (in obeying the Ten Commandments). And the Lord—who is the Spirit (Jesus is the model "Spirit" Paul is telling us to follow and not the Holy Spirit, whose job is to tell us things through prophets and remind us of Jesus as the model "Spirit" to follow)—makes us more and more like him as we are changed into his glorious image.
