In Romans 3:27, Paul contrasted a law of works with a law of faith, in Galatians 3:10-12, he contrasted the Book of the Law with "works of the law", and in Romans 3:31 and Galatians 3:10-12, he said that our faith upholds the Law of Moses in contrast with saying that "works of the law" are not of faith, so that phrase does not refer to the Law of God. God is trustworthy, therefore His law is also trustworthy (Psalms 19:7), so the way to trust in God is by obediently trusting in His law, it would be contradictory for someone to take the position that we should trust in God for salvation but not in His instructions, and the positions that God is a giver of untrustworthy instructions that are not of faith denies the trustworthiness and faithfulness of God.
In Matthew 4:15-23, Christ began his ministry with the Gospel message to repent for the Kingdom of God at hand, which was a light to the Gentiles, and the Law of Moses was how his audience knew what sin is (Romans 3:20), so repenting from our disobedience to it is a central part of the Gospel message. In Psalms 119:142, the Law of Moses is truth, and in John 8:31-36, it is the transgression of the Law of Moses the puts us into bondage while the truth sets us free.
In 1 John 3:4-10, those who are not doers of righteous works in obedience to the Law of Moses and not children of God, and in Romans 8:4-14, Paul contrasted those who are born of the Spirit with those who have minds set on the flesh who are enemies of God who refuse to submit to the Law of Moses.
In Psalm 119:29-30, he wanted to put false ways far from him, for God to be gracious to him by teaching him to obey the Law of Moses, and he chose the way of faith by setting it before him, so this has always been the one and only way of salvation by grace through faith. Christ also set a sinless example for us to follow of how to walk in obedience to the Law of Moses and we are told to follow his example (1 Peter 21-22) and that those who are in Christ are obligated to walk in the same way that he walked (1 John 2:6). So grace and truth came through Jesus because he spent his ministry teaching us to obey the Law of Moses by word and by example.
God has not commanded anything that is not in accordance with walking in the Spirit, but rather God's character traits are the fruits of the Spirit and the Law of Moses is God's instructions for how to embody His character traits, which is why the Spirit has the role of leading us to obey it (Ezekiel 36:26-27). The Son is God's Word made flesh and the Law of Moses is God's Word (Deuteronomy 5:31-33). The Son is the radiance of God's glory and the exact likeness of His character (Hebrews 1:3), which he embodied through His works by setting a sinless example for us to follow that can equivalently be described either as walking in the Spirit or as walking in obedience to the Law of Moses.
“in Galatians 3:10-12, he contrasted the Book of the Law with "works of the law",”
hes not contrasting the book of the law with its works in Galatians 3 at all .
he’s explaining the law and the curse written in it and showing faiths superiority over it again just have to read it
“Know ye therefore that
they which are of faith, the same are the children of Abraham.
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. But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith. And the law is not of faith: but, The man that doeth them shall live in them.
Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; ( until Jesus came )
and it was ordained by angels in the hand of a mediator. Now a mediator is not a mediator of one, but God is one.
Is the law then against the promises of God? God forbid: for
if there had been a law given which could have given life, verily righteousness should have been by the law. But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.
But
before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed.
Wherefore
the law was our schoolmaster to bring us unto Christ, that we might be justified by faith. But
after that faith is come, we are no longer under a schoolmaster.( the law ) For ye are all the children of God by faith in Christ Jesus.”
Galatians 3:7, 10-12, 19-26 KJV
“and Galatians 3:10-12, he said that our faith upholds the Law of Moses”
lol what ?
“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. But that
no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith. And
the law is not of faith: but, The man that doeth them shall live in them.”
Galatians 3:10-12 KJV
you read this as saying “ our faith upholds the law of Moses ?”

I think that’s what happens when we are kissing information like this for instance addressing your idea about Moses law
“But there rose up certain of
the sect of the Pharisees which believed, saying, That it was needful to circumcise them, and to command them to keep the law of Moses. And the
apostles and elders came together for to consider of this matter.
( I encourage you to read the entire discussion but thier conclusion is clear )
forasmuch as
we have heard, that certain which went out from us have troubled you with words, subverting your souls, saying, Ye must be circumcised, and keep the law: to whom we gave no such commandment:”
Acts 15:5-6, 24 KJV
of course some find it hard to accept what the apostles taught but I mean if someone wants to be on this group it’s …… a chcoice lots of them seem to really want to make
“knowing this, that
the law is not
made for a righteous man, but
for the lawless and disobedient, for the ungodly and for sinners, for unholy and profane, for murderers of fathers and murderers of mothers, ( thou shall not kill , honor thy mother and father) for manslayers, for whoremongers, for them that defile themselves with mankind, for menstealers, for liars, ( thou shall not lie ) for perjured persons, ( thou shalt bear false witness ) and if there be any other thing that is contrary to sound doctrine;”
1 Timothy 1:9-10 KJV
Repetetively
“Wherefore, my
brethren, ye also are become dead to the law by the body of Christ;
that ye should be married to another, even to him who is raised from the dead, that we should bring forth fruit unto God.”
Romans 7:4 KJV
“For
I through the law am dead to the law, that I might live unto God.”
Galatians 2:19 KJV
“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. But that
no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith. And
the law is not of faith: but, The man that doeth them shall live in them.”
Galatians 3:10-
“Now we know that
what things soever the law saith, it saith to them who are under the law:
that every mouth may be stopped, and all the world may become guilty before God. Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.”
Romans 3:19-20 KJV
“The sting of death is sin; and
the strength of sin is the law.”
1 Corinthians 15:56 KJV
“For the priesthood being changed,
there is made of necessity a change also of the law.”
Hebrews 7:12
We have to obey Christ and the gospel not Moses and Israel’s law for thier land two different covenants gotta leave the old behind or will never see the new … it’s like a blindfold
“and not as
Moses, which put a vail over his face, that
the children of Israel could not stedfastly look to the end of that which is abolished: but
their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ.
But even unto this day, when Moses is read, the vail is upon their heart.”
2 Corinthians 3:13-15 KJV
again can’t obey Moses and also Jesus
“Ye have heard that
it hath been said, An eye for an eye, and a tooth for a tooth
moses wrote this )
but I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.”
Matthew 5:38-39 KJV
We can’t live eye for an eye retaliating equally and also turn the other cheek and not retaliate in kind when someone offends us . They are opposite directives because they are different covenants and two different mediators two different preisthoods ect ect
