Well, obviously if there is no law, sin is dead because without the law, the sinful self cannot be displayed.
8 But sin, taking opportunity by the commandment, produced in me all manner of evil desire. For apart from the law sin was dead.
Look at the full context.
It is because of sinful desires that cause man to break the law.
7 What shall we say then? Is the law sin? Certainly not! On the contrary, I would not have known sin except through the law. For I would not have known covetousness unless the law had said, “You shall not covet.”[a] 8 But sin, taking opportunity by the commandment, produced in me all manner of evil desire. For apart from the law sin was dead. 9 I was alive once without the law, but when the commandment came, sin revived and I died. 10 And the commandment, which was to bring life, I found to bring death. 11 For sin, taking occasion by the commandment, deceived me, and by it killed me. 12 Therefore the law is holy, and the commandment holy and just and good.
Actually if you read this in context, law is supposed to be good but then it condemns as well due to man's sinful nature.
So basically if you are reading in this context, what it says is that you should not try to overcome sin by your own effort(flesh) but through the holy spirit.
3 For what the law could not do in that it was weak through the flesh, God did by sending His own Son in the likeness of sinful flesh, on account of sin: He condemned sin in the flesh, 4 that the righteous requirement of the law might be fulfilled in us who do not walk according to the flesh but according to the Spirit. 5 For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit, the things of the Spirit. 6 For to be carnally minded is death, but to be spiritually minded is life and peace. 7 Because the carnal mind is enmity against God; for it is not subject to the law of God, nor indeed can be. 8 So then, those who are in the flesh cannot please God.
If you are coveting, you are still sinning. If you remain in the flesh, you cannot get rid of the temptation to covet but if you are in spirit,
you should be able to overcome.Your assumption is that law is something that is bad is a wrong assumption to begin with. Correct me if i am wrong. Because you associate law with self effort. Law is not self effort. It is the rules that God has set and because man hates God(sin), he does not follow the rules.
Even the passage says explictly that the law is holy and the commandments are holy. So how can you associate something holy with something that is unholy(self effort)
I know where you are coming from. But then if a person continues sinning, it is very likely that the Grace of God isn't in him. I mean let's look it from a logical perspective. What is the difference between a Christians who continues with his sin and a non Christian.
Not something bad, The Law of God is needed but it is something that will stop you from getting closer to God because every time you sin, the Law causes a distance between you and God.
If the Law is what God wanted to institute for Man, Christ need not come. Point No 1.
If you say that the Law has nothing to do with Self Effort, then why Christ came to set us free from the Law?
Try and understand from that perspective. (Galatians 4:5)
