Huh? And what scriptural proof do you have for that?
And what exactly is the Moses covenant?
What covenant did Jesus' death fulfilled?
Here is the logic
original sin or intrinsic reprobation (my words) or divine curse is refuted by
Deuteronomy 24
16The fathers shall not be put to death for the children, neither shall the children be put to death for the fathers: every man shall be put to death for his own sin.
Therefore to summarize the narrative of Adam's fall -something that was freely given by God the garden of Eden and was lost due to Adams conduct. This was access to the Tree of Life
I will paraphrase with my language. Adam's perfected genome was insufficient to maintain a relationship with God. So the genome was permitted to live a animals existence and die. God is not obligated to sustain a disobedient creature.
Genesis 3
22And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever: 23Therefore the LORD God sent him forth from the garden of Eden, to till the ground from whence he was taken. 24So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life.
What is the tree of life ? It is a tree of healing not a tree of immortality as per Augustine (per my best estimate of said false doctrine). It is the healing mechanism (my words) that can sustain life given by God
Ezekiel 47
12And by the river upon the bank thereof, on this side and on that side, shall grow all trees for meat, whose leaf shall not fade, neither shall the fruit thereof be consumed: it shall bring forth new fruit according to his months, because their waters they issued out of the sanctuary: and the fruit thereof shall be for meat, and the leaf thereof for medicine.
The new heaven and the new earth that is promised by the Most Merciful God are trees everywhere for obedient sons.
Revelation 22
1And he shewed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb. 2In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations. 3And there shall be no more curse: but the throne of God and of the Lamb shall be in it; and his servants shall serve him: 4And they shall see his face; and his name shall be in their foreheads. 5And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.
The Mosaic Covenant - it is the law as handed to Moses at Mount Sinai to be obeyed by the freed slaves of pharaoh.
Exodus 19
1In the third month, when the children of Israel were gone forth out of the land of Egypt, the same day came they into the wilderness of Sinai. 2For they were departed from Rephidim, and were come to the desert of Sinai, and had pitched in the wilderness; and there Israel camped before the mount. 3And Moses went up unto God, and the LORD called unto him out of the mountain, saying, Thus shalt thou say to the house of Jacob, and tell the children of Israel; 4Ye have seen what I did unto the Egyptians, and how I bare you on eagles' wings, and brought you unto myself. 5Now therefore, if ye will obey my voice indeed, and keep my covenant, then ye shall be a peculiar treasure unto me above all people: for all the earth is mine: 6And ye shall be unto me a kingdom of priests, and an holy nation. These are the words which thou shalt speak unto the children of Israel.
Matthew 5
17Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
In fact all agreements between God and man is negotiated by Jesus Christ.
1 Timothy 2
5For there is one God, and one mediator between God and men, the man Christ Jesus;
Jesus' Death fulfilled the perfect man Adam genomes dying before the flood
Genesis 9
1And God blessed Noah and his sons, and said unto them, Be fruitful, and multiply, and replenish the earth. 2And the fear of you and the dread of you shall be upon every beast of the earth, and upon every fowl of the air, upon all that moveth upon the earth, and upon all the fishes of the sea; into your hand are they delivered. 3Every moving thing that liveth shall be meat for you; even as the green herb have I given you all things. 4But flesh with the life thereof, which is the blood thereof, shall ye not eat. 5And surely your blood of your lives will I require; at the hand of every beast will I require it, and at the hand of man; at the hand of every man's brother
will I require the life of man.
