The jesus who came understood the purpose of the law that it was given so when he came, his people would know who he was and why he came.
why would you want to go back to that which can only condemn, and not to that which can save (the fulfiment of the law)
How did you get to the point of understanding that the OT is only for condemnation? That is a blind belief and a false accusation to those of us whose only way to salvation is through Jesus Christ and He alone is the root and nourishment to our branches. However, the branches will with goodness nourishing will produce good fruit, which is the evidence of what the branches are rooted in. Does bad seeds produce good fruit? Does good seeds, in good soil produce bad fruit?
What does good fruit look like?
Mat_5:19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
Mat_11:11 Verily I say unto you, Among them that are born of women there hath not risen a greater than John the Baptist: notwithstanding he that is least in the kingdom of heaven is greater than he.
Luk_7:28 For I say unto you, Among those that are born of women there is not a greater prophet than John the Baptist: but he that is least in the kingdom of God is greater than he.
How will you know the real Jesus since He is coming again a Second time if you refuse to know that Jesus and the Father are one, and that the Old Testament is not done away with but is the foundation of the scriptures?
The Old Testament is (also of many things and many layers of applications and understandings) so that Jesus' people will know who he is and He has come and we will not be deceived by the False Prophets and the antichrists.
Do you know and rehearse the LORD's Fall feasts? (Lev. 23) (Perhaps not because it is of Torah/OT/God's instructions and love letter to His people/and to Jesus' sheep) Do you study when and what the Feast of Trumpets is, the Day of Atonement, and the Feast of Tabernacles and the Last Great Eighth Day?
If you refuse to know and understand these things, you are blind to what is coming in the future, the tribulations and the last days and the Day of the Lord. Obviously, I don't hold to replacement theology but believe Christians are to be added to the commonwealth of Israel sustained through the Root of our Faith (the work and passion of Jesus) so that we might bear Fruit of our Faith (good works by the indwelling of the Holy Spirit and the law written on our hearts - Jeremiah 31:31-33/Hebrews 8:6-13
Zec 8:23 Thus saith the LORD of hosts;
In those days it shall come to pass, that
ten men shall take hold out of all languages of the
nations (Gentiles), even shall take hold of the skirt of him that is a Jew, saying, We will go with you: for we have heard that God is with you.
Ten men represents the House of Israel and the lost sheep. God divorced the House of Israel God cannot break His own law, namely the Deut. 24:1-4.
Deu 24:1 When a man hath taken a wife, and married her, and it come to pass that she find no favour in his eyes, because he hath found some uncleanness in her: then let him write her a bill of divorcement, and give it in her hand, and send her out of his house.
Deu 24:2 And when she is departed out of his house, she may go and be another man's wife.
Deu 24:3 And if the latter husband hate her, and write her a bill of divorcement, and giveth it in her hand, and sendeth her out of his house; or if the latter husband die, which took her to be his wife;
Deu 24:4 Her former husband, which sent her away, may not take her again to be his wife, after that she is defiled; for that is abomination before the LORD: and thou shalt not cause the land to sin, which the LORD thy God giveth thee for an inheritance.
Jesus is God with us in the flesh and He made a renewed covenant for all the tribes and the foreigners who have accepted the God of Israel (Like Ruth did). Paul was given understanding to the mystery as well as ministry to the Gentiles /Nations/Ten tribes to bring them back into the house of the Lord/Kingdom. Romans 7 (Not for those who do not know the law)
Rom 7:1 Know ye not, brethren,
(for I speak to them that know the law,) how that the law hath dominion over a man
as long as he liveth?
Rom 7:2 For the woman which hath an husband is bound by the law to her husband so long
as he liveth; but
if the husband be dead, she is loosed from the law of her husband.
Rom 7:3 So then if, while her husband liveth, she be married to another man, she shall be called an adulteress:
but if her husband be dead, she is free from that law; so that she is no adulteress, though she be married to another man.
Rom 7:4 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.
