I don't think it is wise, ever, to disregard the word of God. God gave the first covenant and improved it with the second covenant.
It’s a new covenant seperate from the one Jesus fulfilled
“Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah: not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD:”
Jeremiah 31:31-32
there’s a place where one reaches and ends Christ coming and eventually dying after he preached the word of God is the culmination of the old covenant it’s not two in one or one that failed and then was improved
it’s two testaments one came through Moses that’s the one made with israel when he led them from Egypt that’s the covenant that isn’t crossing to the new
“The
law and the prophets were until John:
since that time the kingdom of God is preached, and every man presseth into it.”
Luke 16:16 KJV
the law and prophets reach to Jesus and Jesus preached the new covenant word the gospel of his kingdom that’s not what Moses ever preached nothing g regarding Gods kingdom but earths kingdom Israel’s kingdom is what it was about that covenant was broken
when you try to make Moses words the same as Jesus words your missing where the covenant ends and new begins.
This is how incompatible Moses commands were with Jesus
“Ye have heard that
it hath been said, An eye for an eye, and a tooth for a tooth: ( Moses law exodus 21:23-24 )
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
you cannot obey Moses and what he said. And also Jesus and what he said because they aren’t the same they are contrary not just slightly different it is “ repay an offense with equal offense v don’t take revenge and repay evil for evil I will repay saith the lord “
those two instructions are contrary you can’t obey both of you obey Moses and repay offense with offense then you are violating Jesus word , if you don’t obey Moses and repay the offense the. You’ve disobeyed the old and obeyed Jesus
but you ca t take revenge and also not take revenge it’s not possible to do two things and avoid doing the other you have to choose New Testament word of Christ or Old Testament word for Israel
you have this law of Moses that you can try to be saved by
“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
We can try to be saved by that law the old covenant or this once you take the law out of the equation because Christ took it away for us fulfilling it and giving us a better word the gospel
“But
now the righteousness of God without the law is manifested, being
witnessed ( foretold ) by the law and the prophets; even the
righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: for all have sinned, and come short of the glory of God; being justified freely by his grace through the redemption that is in Christ Jesus:”
Romans 3:21-24 KJV
That righteousness for believers there mentioned is this
“And he said unto them, Go ye into all the world, and
preach the gospel to every creature. He that believeth and is baptized shall be saved; but he that believeth not shall be damned.”
Mark 16:15-16 KJV
It only comes from the gospel the law brought forth the messiah and he. Brought forth faith to be saved
You have to leave the law behind like an educator once you achieve education the teacher served thoer purpose the law was like that schoolteacher about sin we leave it behind and now embrace the gospel the law was before faith came forth
“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.”
Galatians 3:23-25 KJV
The law making us guilty and aware of sin is what brings a believer tonjesus only known sinners who believe in God are going to ever accept a savior and atonement fornthier sins the law is important but it only teaches to where Jesus arrives
