Revelation 1:8 I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.
God is, and was, and is to come, he is the I AM.
He does never change, neither his laws and commandments.
17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
18 For verily I say unto you, Till heaven and earth pass away, not one jot or one tittle shall pass from the law.
The Law of Moses has several sets of laws:
Laws enforcing the 10 commandments
The sacrificial laws of Moses are fulfilled by the perfect sacrifice of the Son of Man on the cross.
Doves lambs and oxen are figures of the pure Sacrifice that was to come, you can easily discern who those animals represent. They are pure animals.
Abel did sacrifice to the Lord: that was taught to men at the very beginning.
Noah did sacrifice when exiting the ark: that knowldge survived to the flood.
Job did sacrifice, yet he was not an Israelite: the whole earth had that knowledge inherited along with the Commandments.
Jesus Christ fulfilled the first four feasts: Passover, Unleaven bred, Fisrt fruits and Weeks. Three more are to be fulfilled at his return: Trumpets, Yom Kippour, Tabernacles.
The laws have'nt changed. The Law is right. It is a standard, a reference. Living by the law guarantees from sin.
We are free in Christ, meaning that we do not have to stick to the law (how could we, while living un pagan states ?). We know better, the guidance of the Holy Spirit.
Even Israel at the time did not respect the law of Moses. How far away are we now ?
How far to the right and to the left are our ways now ?
Deuteronomy 5:32 Ye shall observe to do therefore as the LORD your God hath commanded you: ye shall not turn aside to the right or to the left.
Exodus 23:3 Thou shalt not wrest the judgment of the poor in his cause
The letter of divorce was authorized because of the hardness of our hearts. Jacob did not divorce Leah on the morning. He honored his wife and waited seven more years to marry Rachel.
We should not work every seven years, redistribute riches every 50 years.
Good is good, evil is evil. Read the Law for yourself, you will see how free and just the world would be under this law compared to the rules in place right now.
Israel was a numerous people, the Land is very small, so that it is not a matter of population.
Discern the spirit of the Law, try to apply it where you can in your life: take care of strangers, feed them, let the poor live from your abundance. But don't justify the poor because he is poor.
2 Thessalonians 3:10 For even when we were with you, this we commanded you, that if any would not work, neither should he eat.
You have the right to defend yourself, to seek reparation. But the Lord himself told you that you would better be patient, and let him be the judge.
I am not saying that we are to call evil good. Things need to be said first, truth exposed. Then forgive.
Be content with what is given to you, do your best with it.
If you have a lot, multiply it and enrich the Kingdom. If you have few, it doesn't mean nothing is expected from you: hear the parable of the talents, Matthew 25:14.
We live in Egypt, where evil is called good and good evil.
Sometimes it is good to read what was called Good at the time of Moses, because evil at that time was a fraction of what it is now.
Beyond that, you can't understand the new testament, prophecies or Revelation if you don't know the Law of Moses. Every aspect of it has a prophetic meaning.
As Paul said:
