I understand it according to Mt 7:12, that the law of Christ sums up the law or Moses,
and according to Ro 13:8-10 that it fulfills the law (Gal 5:6).
I understand it to mean all the myriad regulations of the Mosaic law do not apply to those under the new covenant.
I understand it to mean that if we love God and our neighbor, we will be necessarily practicing the law of God.
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.
Jesus quote from the Torah and prophets:
Lev 19:18 Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbour as thyself: I am the LORD.
Jer 7:5 For if ye throughly amend your ways and your doings; if ye throughly execute judgment between a man and his neighbour;
Jer 7:6 If ye oppress not the stranger, the fatherless, and the widow, and shed not innocent blood in this place, neither walk after other gods to your hurt:
Jer 7:7 Then will I cause you to dwell in this place, in the land that I gave to your fathers, for ever and ever.
Nothing new about loving our neighbor. Why do you call it "new"? Jesus is reiterating the Torah and prophets, right?
Rom 13:8 Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law.
Paul is reiterating the Torah and prophets and Y'shua, is he not? Nothing new here?
I see this verse often quoted:
Gal 5:3 For I testify again to every man that is circumcised, that he is a debtor to do the whole law.
But again, it is reiterating from OT:
Neh 9:29 And testifiedst against them, that thou mightest bring them again unto thy law: yet they dealt proudly, and hearkened not unto thy commandments, but sinned against thy judgments, (
which if a man do, he shall live in them
and withdrew the shoulder, and hardened their neck, and would not hear.
Why? Because there are curses in the law for not being obedient:
Gal 3:10 For as many as are of the
works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them.
Gal 3:11 But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.
Gal 3:12 And the law is not of faith: but, The man that doeth them shall live in them.
Gal 3:13 Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree:
I have seen here a discussion that the law which has curses for disobedience has become the law is a curse. That would not be a true statement. Why?
Deu 30:1 And it shall come to pass, when all these things are come upon thee, the blessing and the curse, which I have set before thee, and thou shalt call them to mind among all the nations, whither the LORD thy God hath driven thee,
Deu 30:2 And shalt return unto the LORD thy God, and shalt obey his voice according to all that I command thee this day, thou and thy children, with all thine heart, and with all thy soul;
Deu 30:3 That then the LORD thy God will turn thy captivity, and have compassion upon thee, and will return and gather thee from all the nations, whither the LORD thy God hath scattered thee.
They were cursed and taken into captivity for disobeying the law, not for keeping it. Since we know God neither changes nor will He lie, that scripture still stands today.
Again, God does not change nor does He lie:
Psa 1:1 Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful.
Psa 1:2 But his
delight is in the law of the LORD; and in his law doth he meditate day and night.
Psa 19:8 The statutes of the LORD are right, rejoicing the heart: t
he commandment of the LORD is pure, enlightening the eyes.
Psa 19:9 The fear of the LORD is clean, enduring for ever: the judgments of the LORD are true and righteous altogether.
Psa 19:10 More to be desired are they than gold, yea, than much fine gold: sweeter also than honey and the honeycomb.
Jos 1:8 This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that
thou mayest observe to do according to all that is written therein: for then thou shalt
make thy way prosperous, and then thou shalt have good success.
Did the Torah or "law" ever make someone not prosperous or to have good success? Yes! If the law is not used properly.
1Ti_1:8 But we know that the law is good, if a man use it lawfully;
So how does one use the law lawfully? AGain, the fuller answer is from Torah.
Deu 4:6 Keep therefore and do them; for
this is your wisdom and your understanding in the sight of the nations, which shall hear all these statutes, and say, Surely this great nation is a wise and understanding people.
Deu 4:7 For what nation is there so great,
who hath God so nigh unto them, as the LORD our God is
in all things that we call upon him for?
Deu 4:8 And what nation is there so great,
that hath statutes and judgments so righteous as all this law, which I set before you this day?
That is God's Law and not Law of Moses.
God will not be mocked, rest assured. Gal_6:7 Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.
Jud_1:18 How that they told you there should be mockers in the last time, who should walk after
their own ungodly lusts.
Eph 5:6 Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the
children of disobedience.
Col 2:8 Beware lest any man spoil you through philosophy and vain deceit, after
the tradition of men, after the rudiments of the world, and not after Christ.
Many have been "spoiled" by this false teaching that Christ did away with anything of the Torah. Believing God did not require the law to be written on their hearts, therefore they could not achieve obedience. Some were able and it was counted to them as righteousness.
David had the law written on his heart. Psa 40:8 I delight to do thy will, O my God: yea, thy law is within my heart.
Do you see that? Delighting to do God's will is equal to the law being written on my heart.
I had to start somewhere in this walk of understanding. It started when I obeyed the Sabbath commandment. And from there, well just like those disciples in Acts: Act_5:32 And we are his witnesses of these things; and so is also the Holy Ghost,
whom God hath given to them that obey him.
They didn't say that they obeyed Jesus' new commandments, no, God gives the Holy Ghose (oil fuel for our lamps - think ten virgin parable) to those who obey him.
As a matter of fact, all of the parables can be perfectly understood if you properly use the law lawfully. ie...keep my commandments and my commandments are not grievous, says our Lord Jesus. His commandments are not doing away with any of of God's laws, He came to fully preach and teach the Torah so that we could understand it correctly, not to do away with it.
