I fully understand everything you have wrote in your post apart from what you wrote here. and for most part your post is correct. But the holy laws of holy laws which can be seen in the whole bible, and in allmost every verse, is for being wise to defeating the enemy. Which is something we have to suit up boot up for every day, Now i know that Its Jesus who defeats the enemy, How ever something is very important that we are required to do and that is to obey. Because Gods grace is considerate to those who abide in him but also considerate to those who reject him.
There is a warning there. Just as much as there is a warning in Judas who betrayed Jesus and satan entered him.
There are many many more warnings for christians in the form of obeying Gods holy laws and how important it is to do this, because the enemy is looking to steal christians from God as much as none christians. and probably more so christians.
Here we see why
1 peter 5
6 Humble yourselves, therefore, under God’s mighty hand, that he may lift you up in due time. 7 Cast all your anxiety on him because he cares for you.
8 Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour. 9 Resist him, standing firm in the faith, because you know that the family of believers throughout the world is undergoing the same kind of sufferings.
10 And the God of all grace, who called you to his eternal glory in Christ, after you have suffered a little while, will himself restore you and make you strong, firm and steadfast. 11 To him be the power for ever and ever. Amen.
The above laws are for christians being giving clear instructions on behalf of Gods holy laws that we are required toobey and do this for our selfs.
So while you say the law is only given for sinners and for those not born of the holy spirit i say the law is given for much much more.
The most important part of the law whether it be called the law of moses or cerimonial law. or the holy law or whatever, is the whole bible is a set of laws on defeating spiritual wicked high forces. So that they dont lead you a stray, this is the most important part of the law to me not that its for sinners. Jesus himself spoke many of theese laws for that reasons that are just as much as valid for christians today as they where befor the holy spirit was Given, why well many times Jesus speaks highly of the law that is called the law of moses.
One of them being this one
Luke 24:44
Now He said to them, “These are My words which I spoke to you while I was still with you, that all things which are written about Me in the Law of Moses and the Prophets and the Psalms must be fulfilled.”
I realise that you me or everybody can not be freed through the law of moses. how ever we should not forget that the law of moses is the law of God. And the most important part whilst we can not freed by the law of moses we can remain free by obeying the laws that Jesus spoke about. Some of those laws are mirror images of what you call the law of moses,
One of them great laws of Jesus is the same as what you call the law of moses. which proves it isnt the law of moses but the law of Jesus,
deauteronomy 6:5
5 Love the Lord your God with all your heart and with all your soul and with all your strength.
Deuteronomy 10:19-21
New International Version
19 And you are to love those who are foreigners, for you yourselves were foreigners in Egypt. 20 Fear the Lord your God and serve him
These two laws you call the law moses are the same as Jesus greatest law
wrote here
Matthew 22:36-40
36 “Teacher, which is the greatest commandment in the Law?”
37 Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’[
a] 38 This is the first and greatest commandment. 39 And the second is like it: ‘Love your neighbor as yourself.’[
b] 40 All the Law and the Prophets hang on these two commandments.”
There you have it. Its not the law of moses. the law of moses is just an expression.
There is no such law as the law of moses because ultimately those laws came from God
