Sure FIRST -
James 2…for whosoever shall keep the whole law, and yet offend in one point, is guilty of all. For he that said, Do not commit adultery, said also, Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the law. So speak ye, and so do, as they that shall be judged by the law of liberty.
Romans 2:12 For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law (and all have sinned…therefore make by the law and you shall be judged by the law…stumble at the stumbling stone)
NOW WHY
2 Corinthians 3 - 3 Forasmuch as you are manifestly declared to be the epistle of Christ ministered by us, written not with ink, but with the Spirit of the living God; not in tables of stone (like the 10 Commandments), but in fleshy tables of the heart (by the indwelling Spirit of God). 4 And such is the trust have we through Christ toward God: 5 Not that we are sufficient of ourselves to think anything of ourselves (like as if we keep the commandments and others do not); but our sufficiency is of God (because it is not by what we do or have done, but of Christ); 6 Who also hath made us able ministers of the New Testament; not of the letter, but of the spirit: for the letter kills (brings death), but the spirit gives life (His life in us the expectation of glory).
7 But if the ministration of death (the sin consciousness brought on by the Law), written and engraved in stones (that is the 10 Commandments), was glorious, so that the children of Israel could not steadfastly behold the face of Moses because of the glory of his countenance; which glory eventually faded (because by the commandments they were all guilty): 8 How shall the ministration of the Spirit not be even more glorious (who while we were yet sinners Christ dies for the ungodly…by love and grace)?
9 For if the ministration of condemnation be glory, much more doth the ministration of righteousness exceed in glory (that righteousness which is by faith and not works).
10 For even that which was made glorious had no glory in this respect, by reason of the glory that excels (for it never ends). 11 For if that which is done away was glorious, much more is that which remains glorious.
In the Exodus Pentecost (Shavuot), 50 days after the deliverance of Israel, the Lord gave the letter of the Law engraved in stone. It was at Mount Sinai in Arabia (called also Horeb), the mount of God in the land of Jethro of Midian…as Moses came down declaring the Commandments the people fled and 3,000 eternally died
(You shall, you shall, you shall not, you shall not…it is all about “Thou” and the eye turns onto self)
In the Acts Pentecost, 50 days after deliverance of whosoever will that would come, the Lord gave the Spirit, and wrote all we need in our hearts. It was on Mt. Zion, in Jerusalem the city made Holy by God. Jesus went UP giving the Spirit and 3,000 were eternally saved.
(And they went about preaching the wonderful works of God…they glorified Christ, led them to salvation…it’s all about God and the eye turns to Christ…what He said and what He did and His gracious offer of love – 2:37-39)
Through the Law comes the knowledge of sin…though grace the love of God to-usward…the ministry of death was engraved on stone and the ministry of righteousness engraved on our hearts by the knowledge of salvation.
Romans 7: 6 But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter.
7 What shall we say then? Is the 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.
8 But sin, taking occasion by the commandment, wrought in me all manner of concupiscence. For without the law sin was dead.
9 For I was alive without the law once: but when the commandment came, sin revived, and I died.
Alive apart from the law…dead by the law! Alive through Christ’s sufficient and pleasing sacrifice.
Colossians 2 13 And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all your trespasses;
14 Blotting out the handwriting of ordinances that was against us (the Law), which was contrary to us, and took it out of the way, nailing it to his cross.
So He not only nailed our sins to the cross but also the ordinances against us so they no longer have any effect…by grace we are SAVED.
