What Law are you talking about??
There are only two senses of God's Law that I refer to: either the Law of Moses or the Law of God as a general principle of God's requirements under any covenant. The Law of Moses is tied to a specific covenant, whether moral law or ceremonial law--it is a system of temporary justification, and not a system of final justification.
If you keep a moral law under the Law of Moses, such as "Do not kill," it remains an inadquate form of justification, even though the same moral law may be available under the system of Christ. It really matters *under what system* you are obeying Moral Law?
You are confuse on which law is which. Paul says in (Gal. 3:1, 13, 16-17, 19, 24) (v.1) O FOOLISH Ga-la’-tians, who hath bewitched you, that ye should not obey the truth, before whose eyes Jesus Christ hath been evidently set forth, crucified among you? (v.13) Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, CURSED IS EVERYONE THAT HANGETH ON A TREE: What law is this talking about? Let the bible speak for itself
Your quote does not determine anything different from what I just said. The Law of Moses is tied to the Old Covenant, which contains both Moral Law and Ceremonial Law. It is an inadequate system of justification. If anybody thinks just keeping the Moral part of the Law of Moses is adequate, just look at what Jesus said to the Rich Young Ruler....
Matt 19.16 Just then a man came up to Jesus and asked, “Teacher, what good thing must I do to get eternal life?”
17 “Why do you ask me about what is good?” Jesus replied. “There is only One who is good. If you want to enter life, keep the commandments.”
18 “Which ones?” he inquired.
Jesus replied, “‘You shall not murder, you shall not commit adultery, you shall not steal, you shall not give false testimony, 19 honor your father and mother,’ and ‘love your neighbor as yourself.’”
20 “All these I have kept,” the young man said. “What do I still lack?”
21 Jesus answered, “If you want to be perfect, go, sell your possessions and give to the poor, and you will have treasure in heaven. Then come, follow me.”
(v.16) Now to Abraham and his seed were the promises made. He saith not, and to seeds, as of many; but as of One, AND TO THY SEED, which is Christ. (v.17) And this I say, that the covenant, that was confirmed before of God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of none effect.
To sum up what going on here in Galatians, Paul is explaining that Christ came from Abraham seed, and remove the animal Sacrificial law. But in the days of Abraham that animal Sacrificial law never was on the table, and was not needed for Abraham to obey and have faith in God. But the Commandments was always on the table.
You are confusing how Faith saved before or under the system of Law and how Faith is actually tied to Christ's system of justification. Anything prior to the cross of Christ relies on faith that lacks a system of final justification unless it is looking beyond it to Christ's system of justification--a system relying not on self-justification, but on trust in God's mercy.
The Law did not rely on man's record of righteousness, which was flawed. Rather, it relied upon God's mercy. It was not a self-validating system, but rather, a precursor to a new system, which also relied on God's mercy, but added a means of final justification, including Christ's unflawed record of righteousness.
If you remain tied to the Old Covenant system, whether exercising Morality or following Ceremonial Law, you are not relying on Christ's record of righteousness, but on your own flawed record of righteousness. As such, you remain unjustified in the final sense.
Faith is able to look forward to Christ's system of justification even before it is realized. This does not validate pre-Christian Law--rather, it validates Faith as a precursor to the system of Christian justificaiton. It only validates the Law of Moses as an expression of faith that looks beyond the Law to something better.
Faith is ever a system that relies upon God's mercy. Whether a sinner as yet unjustified in the OT era or a sinner justified in the Christian era, faith relies upon God's mercy. It does not depend on the human record of righteousness, which always falls short of final justification. It always looks beyond man's record of righteousness, no matter how valid it is, because any sin will disqualify us. The Law pointed this out, and Christ himself pointed it out.
The presence of faith under the Old Covenant system, or under the Law of Moses, does not validate it as a means of final justification. It only validates the faith that looks necessarily beyond it to a means of final justification through Christ's record and gift of righteousness.
Now pay attention, the law that is being spoken of here came four hundred and thirty years after this covenant. But God’s holy commandments have been around forever even before man was created. Remember that Satan was kicked out of heaven because iniquity (sin) was found in him. And what is sin? The transgression of the law (commandments). Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law. Now we have just read the biblical definition of sin, the transgression (breaking) of the law (commandments.) It doesn’t matter what you or I think sin is, it’s what God says sin is that counts. (1John 3:4)
(v.19) Wherefore then serveth the law? A question is being asked here. Then why should we serve this law? It was added because of transgression, till the seed should come to whom the promise was made; the law that we are talking about here was added because of sin. But we now know that sin is the transgression of the law.
How do you add a law if sin is the transgression of the law?
This just proves my point that there are two senses of God's Law, the general sense requiring obedience to God under all covenants and the technical application of Moses' Law, which involved both Moral Law and Ceremonial Law. What was "added" was the Law of Moses. The "transgression" that previously existed was sin against the general sense of God's Law, requiring obedience under any occasion.
You seem to wish to divide Ceremonial Law from Moral Law as two distinct systems? They aren't. The Law of Moses was strictly Old Covenant. And even though it contained Moral Law, that did not validate the Old Covenant system as a final means of justification.
Again, final justification is based on faith, which looks beyond the Old Covenant and beyond the Law of Moses to the record of Christ's righteousness and his enablement of virtue for those who completely commit to him. Saying the Moral Law remains a valid aspect of the Law of Moses excludes Christ as a necessary means of final vindication. People cannot follow Moral Law alone, excluding dependence on Christ, and be saved.
Because there are two sets of laws, you have God’s holy commandments which abided forever, and you had the animal sacrificial law which was added because of sin, but it was only good until the seed should come to whom the promise was made, and that seed was Jesus.
The Law of Moses clearly was not just "animal sacrifical law." Rather, it was both Moral Law and Ceremonial Law. If you keep the Law prohibiting murder *under the Law of Moses* you cannot obtain final justification--only if your faith looks beyond that system as now obsolete, since Christ has now supplanted it. If you keep God's Law prohibiting murder under the New Covenant you rely on Christ's righteousness, as well as on God's mercy.
It is *Christ's righteousness* that justifies, and our faith relies on that instead of on our moral adherance, which is only representative of our faith in Christ's righteousness. Whatever we do that is right relies upon Christ for our validation.
(v.24) Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith. This animal sacrificial law was only a schoolmaster. (Paul breaks down more of this law in Hebrew 10th Chapter)
I agree--Paul is talking about God's Law residing in two different eras and in two different covenants. That goes without saying.
To understand Paul you must recognize that he opposed the Law of Moses as a system of final justification, but credited it as a moral system and as a system of temporary justification. Paul recognized that the Law of Moses showed in its form of righteousness an example of faith ultimately directed towards Christ as its object, supplanting the temporary system of the Law.
Be Moral, but don't say you're under the Law of Moses. That Law was designed not to validate itself but only to point out our flaws, which delegitimized us. Rather, we are moral now because the Law directed us to Christ, who requires that we depend on him and on his record for moral validation.
