Maybe this will help to explain my view:
7:1 Know ye not, brethren, (for I speak to them that know the law,) how that the law hath dominion over a man as long as he liveth? 7:2 For the woman which hath an husband is bound by the law to her husband so long as he liveth; but if the husband be dead, she is loosed from the law of her husband.
7:3 So then if, while her husband liveth, she be married to another man, she shall be called an adulteress: but if her husband be dead, she is free from that law; so that she is no adulteress, though she be married to another man.
7:4 Wherefore, my brethren, ye also are become dead to the law by the body of Christ; that ye should be married to another, even to him who is raised from the dead, that we should bring forth fruit unto God.
7:5 For when we were in the flesh, the motions of sins, which were by the law, did work in our members to bring forth fruit unto death.
7:6 But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter.
7:7 What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.
7:8 But sin, taking occasion by the commandment, wrought in me all manner of concupiscence. For without the law sin was dead.
7:9 For I was alive without the law once: but when the commandment came, sin revived, and I died.
7:10 And the commandment, which was ordained to life, I found to be unto death.
7:11 For sin, taking occasion by the commandment, deceived me, and by it slew me.
7:12 Wherefore the law is holy, and the commandment holy, and just, and good.
7:13 Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceeding sinful.
7:14 For we know that the law is spiritual: but I am carnal, sold under sin.
7:15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
7:16 If then I do that which I would not, I consent unto the law that it is good.
7:17 Now then it is no more I that do it, but sin that dwelleth in me.
7:18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
7:19 For the good that I would I do not: but the evil which I would not, that I do.
7:20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
7:21 I find then a law, that, when I would do good, evil is present with me.
7:22 For I delight in the law of God after the inward man: 7:23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
7:24 O wretched man that I am! who shall deliver me from the body of this death? 7:25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
8:1 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
8:2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.
8:3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: 8:4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
(King James Bible, Romans)
notice 7:7, Paul said of the law, that he would not known sin but by the law, he would not know lust except the law said thou shalt not covet. That is one of the ten commandments, you see? What the law could not do, for it could only show us our sinfulness for no man can keep the law, Christ did! That is why we celebrate and worship Him on Sunday, He changed everything! Maybe I can search and try to find someone who can explain it better than me, but consider these posts, anyway. Just remember we don't frustrate the grace of Christ by adding to it the Law. We are saved by having believed in Christ who paid for our sins as a free gift, and nothing else. Not belief plus the law, sacraments, a certain church, or rituals or whatever, we are saved by the blood of Christ, his undeserved merit.
2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 2:9 Not of works, lest any man should boast.
2:10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
(King James Bible, Ephesians)
We are saved freely good works following, not to get or keep saved, but because we are saved.
3:20 Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
3:21 But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets; 3:22 Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: 3:23 For all have sinned, and come short of the glory of God; 3:24 Being justified freely by his grace through the redemption that is in Christ Jesus: 3:25 Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; 3:26 To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.
3:27 Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith.
3:28 Therefore we conclude that a man is justified by faith without the deeds of the law.
That should explain it somewhat too, hope all this helps, Peace!
