Romans 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. So the law is the school master which also is the knowledge of sin you see the entire scripture of the five books of Moses teach precept upon precept what is right in the eyes of God and what is wrong in the sight of God . Let's look at one example before we go on to the love of Christ because we have to take a concept of the apostles what they taught who they were and what form of man they were for all the apostle's have to align with Christ and I believe this is agreeable.Romans 7:
7 What shall we say then?
Isthe 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. Even Paul the apostol says that the law is the knowledge of sin therefore knowing this one cannot follow a law according to the carnal man you see the precept of a commandment is very important the principle of what the commandments teaching is more important let's look at the example of Christ
Mathew 7:21-29
21 Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:
note xref-2 [xref-1]
22 But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.
note
23 Therefore if thou bring thy gift to the altar, and there rememberest that thy brother hath ought against thee;
24 Leave there thy gift before the altar, and go thy way; first be reconciled to thy brother, and then come and offer thy gift.
25 Agree with thine adversary quickly, whiles thou art in the way with him; lest at any time the adversary deliver thee to the judge, and the judge deliver thee to the officer, and thou be cast into prison.

26 Verily I say unto thee, Thou shalt by no means come out thence, till thou hast paid the uttermost farthing.
27 Ye have heard that it was said by them of old time, Thou shalt not commit adultery:
xref-2 [xref-1]
28 But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
xref-2
29 And if thy right eye offend thee, pluck it out, and cast
itfrom thee: for it is profitable for thee that one of thy members should perish, and not
that thy whole body should be cast into hell. Here we find that one cannot follow a commandment without knowing the principle behind the commandant as you heard the term but the law was a schoolmaster therefore being a school master it was made for those that are unknowledgeable/ignorant like as a child a child does not have a full understanding therefore they're giving rules touch this not , don't go there because a child's mine does not have the understanding of the father therefore Jesus came to give us the understanding of the father that we may come to know him through the spirit it is not enough to follow a commandment but to learn the principle of why the commandant was there and how to avoid such sins die fighting it in the spirit
