"The Law" - the Torah, the books of Moses, the law of Moses, the Sinai Covenant, etc
i think we all know what this refers to. no, it's not just the 10 commandments. don't be silly. ((James 2:9-10))
we know that righteousness cannot be attained through the law, neither can life:
I do not set aside the grace of God; for if righteousness comes through the law, then Christ died in vain.
(Galatians 2:21)
Is the law then against the promises of God? Certainly not!
For if there had been a law given which could have given life, truly righteousness would have been by the law.
(Galatians 3:21)
a law was given, but it was not one through which righteousness could come, and not one that could give life.
this is puzzling - because the law itself says 'the one who does these things will live by them' ((Leviticus 18:5, Romans 10:5, Galatians 3:12)) - yet by these things, i.e. Torah, no one receives life ((Galatians 2:16, Romans 3:20, Galatians 3:11 etc)).
still, it was given by God, and it is perfect. it was given by God to a specific people at a specific time. ((for more info, read Exodus & Deuteronomy etc))
why? how is this perfect -- how is a law that cannot produce righteousness and cannot give life, the absolute perfect law to be given to this people at this time?
we know too, 'by the law is the knowledge of sin' ((Romans 3:20, 7:7-9 etc)) and 'the law was a schoolmaster' to bring people to Christ ((Galatians 3:24)). so we know some things about the purpose of the law. and we know, 'the letter kills but the Spirit gives life' ((2 Corinthians 3:6)) -- in fact He has made us ministers of a new covenant, 'built on better promises' ((Hebrews 8:6)) -- and the first is 'made obsolete' ((Hebrews 8:13)).
so here is my question ((yay! a question!)), phrased in the form of a few questions, but really it is all one question:
why wasn't the spiritual law given in the first place?
why a Torah of ordinances & statutes & commandments called a 'ministry of death' ((2 Corinthians 3:7)) to go before?
why a law which makes everyone who relies it, under a curse? ((Deuteronomy 27:26, Galatians 3:10))
why require the blood of bulls and goats when it can never take away sin?
why command physical circumcision if it means nothing, but only the circumcision done without human hands is effectual?
why did God give The Law which 'is not of faith' ((Galatians 3:12)) instead of giving faith?
why did grace & truth wait over a thousand years after Moses to come through Jesus Christ ((John 1:17))?
In your original post you asked the question about the promise of life in the law in Leviticus 18:5 which was quoted by Ezekiel and the Galatians as you point out. It is an excellent question and essential to understanding Scripture and the Law and our Salvation through Messiah's obedience.
i was trying to answer the question you asked. The Law was Life to Yahshua because of His obedience in offering His Life which the Law required of Him. In that sense the promise of Life in the Law saved Him and also saves us because of our faith in Him and His Sacrifice for forgiveness of our sins as Hebrews 9 explains.
11 But Messiah being come an High Priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building; 12 Neither by the blood of goats and calves, but by His own blood He entered in once into the holy place, having obtained eternal redemption for us.
13 For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: 14 How much more shall the blood of Messiah, Who through the Eternal Spirit offered Himself without spot to YAH, purge your conscience from dead works to serve the living YAH?
15 And for this cause He is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance. 16 For where a testament is, there must also of necessity be the death of the testator. 17 For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.
18 Whereupon neither the first testament was dedicated without blood. 19 For when Moses had spoken every precept to all the people according to the law, he took the blood of calves and of goats, with water, and scarlet wool, and hyssop, and sprinkled both the book*, and all the people, 20 Saying, This is the blood of the testament which YAH hath enjoined unto you. 21 Moreover he sprinkled with blood both the tabernacle, and all the vessels of the ministry. 22 And almost all things are by the law purged with blood; and without shedding of blood is no remission.
23 It was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these. 24 For Messiah is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of YAH for us: 25 Nor yet that He should offer himself often, as the high priest entereth into the holy place every year with blood of others; 26 For then must He often have suffered since the foundation of the world: but now once in the end of the world hath He appeared to put away sin by the sacrifice of Himself.
