First of all, I think you are confused about the reason for sacrifices. When Israel first came out of Israel, before they rebelled, there was no need for animal sacrifices.
Jeremiah 7:22 For I spake not unto your fathers, nor commanded them in the day that I brought them out of the land of Egypt, concerning burnt offerings or sacrifices:
23 But this thing commanded I them, saying, Obey my voice, and I will be your God, and ye shall be my people: and walk ye in all the ways that I have commanded you, that it may be well unto you.
Got that? If Israel had obeyed the Voice of God, all would have been well for them without any animal sacrifices being required. Do not say God asked the impossible. Do you think Satan is so powerful it is impossible for men to obey God? Are men nothing except puppets of Satan -- perhaps they are if they hearken to the voice of the serpent, but must men listen to the serpent?
The people of Israel later got the wrong idea about animal sacrifices, perhaps the same idea you hold. God was not pleased.
Isaiah 1:11 To what purpose is the multitude of your sacrifices unto me? saith the Lord: I am full of the burnt offerings of rams, and the fat of fed beasts; and I delight not in the blood of bullocks, or of lambs, or of he goats.
You seem to believe God is unreasonable, asking the impossible from people. Was it possible to keep the law perfectly? It seems that perhaps it was.
Genesis 6:9 These are the generations of Noah: Noah was a just man and perfect in his generations, and Noah walked with God.
God was not joking when He spoke to Abraham:
Genesis 17:1 And when Abram was ninety years old and nine, the Lord appeared to Abram, and said unto him, I am the Almighty God; walk before me, and be thou perfect.
And what of Job?
Job 1:1 There was a man in the land of Uz, whose name was Job; and that man was perfect and upright, and one that feared God, and eschewed evil.
It is up to each of us whether we hear every word that comes from the mouth of God and then obey -- or whether we "hearken to the serpent." God gave us that choice. Do not say it's not possible. With God all things are possible.
Luke 4:4 And Jesus answered him, saying, It is written, That man shall not live by bread alone, but by every word of God.
Deuteronomy 30:19 I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live:
Do not say it is impossible to choose life.
What “ I” say is as insignificant as what “you” say...... Got That?
Let’s see what God’s Word says about your Precious Law.....
I may have posted this before......regardless , some need to read it again....
