And a little more on the law from the Word of OT and our benefits:

Psa 119:34 Give me understanding, and I shall keep thy law; yea, I shall observe it with my whole heart.
Psa 119:44 So shall I keep thy law continually for ever and ever.
Psa 119:53 Horror hath taken hold upon me because of the wicked that forsake thy law.
Psa 119:72 The law of thy mouth is better unto me than thousands of gold and silver.
Psa 119:77 Let thy tender mercies come unto me, that I may live: for thy law is my delight.
Psa 119:97 MEM. O how love I thy law! it is my meditation all the day.
Psa 119:113 SAMECH. I hate vain thoughts: but thy law do I love.
Psa 119:136 Rivers of waters run down mine eyes, because they keep not thy law.
Psa 119:165 Great peace have they which love thy law: and nothing shall offend them.
Pro 6:23 For the commandment is a lamp; and the law is light; and reproofs of instruction are the way of life:
Pro 28:4 They that forsake the law praise the wicked: but such as keep the law contend with them.
Pro 28:9 He that turneth away his ear from hearing the law, even his prayer shall be abomination.
Pro 29:18 Where there is no vision, the people perish: but he that keepeth the law, happy is he.
Isa 5:24 Therefore as the fire devoureth the stubble, and the flame consumeth the chaff, so their root shall be as rottenness, and their blossom shall go up as dust: because they have cast away the law of the LORD of hosts, and despised the word of the Holy One of Israel.
Isa 30:9 That this is a rebellious people, lying children, children that will not hear the law of the LORD:
Jer 6:19 Hear, O earth: behold, I will bring evil upon this people, even the fruit of their thoughts, because they have not hearkened unto my words, nor to my law, but rejected it.

Hos 4:6 My people are destroyed for lack of knowledge: because thou hast rejected knowledge, I will also reject thee, that thou shalt be no priest to me: seeing thou hast forgotten the law of thy God, I will also forget thy children.
Amo 2:4 Thus saith the LORD; For three transgressions of Judah, and for four, I will not turn away the punishment thereof; because they have despised the law of the LORD, and have not kept his commandments, and their lies caused them to err, after the which their fathers have walked:
Mat 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
Mat 7:12 Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets.
Luk 16:17 And it is easier for heaven and earth to pass, than one tittle of the law to fail.
I am sure there are many more scriptures that tell us the law is good, holy, and for our benefit. The failing of not being able to keep them 100% perfectly is reserved only for the One who could keep them 100% perfectly and He did this not just for Himself, but for all mankind of all the world, once dying and then living forever and forever as our High Priest making intercession for me and for you, because we are still in these bodies of flesh, although beit we are guided and stregnthened by the Holy Spirit in this fleshly life. To be separate from the world, means to unite ourselves with the whole Word of God and not separate Jesus from the Word of OT, as He is the author of the OT.
ET - you appear to be hung up on the idea that because we are unable to keep the OT Law perfectly, and to do all that it says, that it is therefore "NOT GOOD". I see things differently than you do. All the Word is good, holy and perfect, and I can't separate myself from the OT just because I once was a gentile Christan (now an ingrafted Israelite through the blood of Messiah Yeshua). To see the whole Bible as one flawless and seamless flow is the result I recieved when I opened my heart to understanding and not putting false doctrines of separation of Israel from the church or believing that Christ nullified the Law. No, we are all one in God and His Law is for both Israel and the church (who is engrafted into Israel through the blood of Messiah Yeshua.)
Enough said. I don't think anything I share of my heart and how I love the Law of God, fully preached by Rabbi/Master Yeshua/Jesus, will have any effect on your present understanding. I withdraw from any further comment. Shalom.
