Here's a covenant from the Bible:
Note the use of the word "covenant." The word "covenant" appears nowhere in Genesis 3. Genesis 3:15-21 doesn't read like a covenant. To me it reads like a curse:
I don't understand how you were able to read it as a covenant.
Let's talk about the things that God did
not give to Adam and Eve when he booted them out of the garden of Eden:
- He said nothing about eternal life. If he had a plan for Adam and Eve to live an eternal life in union with God, he said nothing about when that would happen, or how. In fact, God didn't say one word about eternal life until four THOUSAND years later, through the mouth of Jesus.
- He didn't give them any rules by which to live. If God granted to Adam and Eve the opportunity to earn an eternal life in his company, he didn't tell them what they had to do to earn eternity. He just threw them out and left them on their own.
So I don't get why you think God was planning for Adam and Eve to live in union with him. It appears to me that you are imposing a Christian eschatology on pre-Christian writings. That, as I see it, is a common fault in the way Christians read the Old Testament.
Perhaps you don’t understand Covenant.
Covenant is a binding agreement where words are spoken and the strongest of these covenants is when there is a shedding of blood. If I am not mistaken, even our Jewish brothers believe it is a messianic promise.
The covenant is found in Gen 3:15 with a prophetic utterance of God’s answer to sin:
Genesis 3:15 New King James Version 15 And I will put enmity Between you and the woman, And between your seed and her Seed; He shall bruise your head, And you shall bruise His heel.”
The shedding of blood is found here when God killed an animal or animals to make clothing:
verse 21 Also for Adam and his wife the Lord God made tunics of skin, and clothed them. (replacing Adam’s efforts to hide his sin behind fig leaves - verse 7 Then the eyes of both of them were opened, and they knew that they
were naked; and they sewed fig leaves together and made themselves coverings.)
What is the significance?
There really isn’t a “seed of a woman” - seed comes from a man. The “Seed” is actually speaking of Jesus being birthed through a woman without the “seed of man”. There is no other reference of a “seed of a woman”. A seed - not seeds of many but of one.
Galatians 3:16 Now to Abraham and his Seed were the promises made. He does not say, “And to seeds,” as of many, but as of one, “And to your Seed,” who is Christ.
The bruising speaks of death. Satan will bruise his heal (or cause death to come to Jesus) but he will bruise Satan’s head (destroy his power of spiritual sin and death). He sealed it with the shedding of blood and covering mankind with a temporal covering of a blood covenant until He could cloth us with His robe of righteousness.
The Jonathon Targum says it this way:
And I will put enmity between thee and the woman, and between the seed of thy son, and the seed of her sons; and it shall be when the sons of the woman keep the commandments of the law, they will be prepared to smite thee upon thy head; but when they forsake the commandments of the law, thou wilt be ready to wound them in their heel. Nevertheless for them there shall be a medicine, but for thee there will be no medicine; and they shall make a remedy for the heel in the days of the King Meshiha.
The Bible doesn’t write down everything God said - there wouldn’t be enough space to write it all. But somewhere Abel learned about the shedding of blood and the offering of a lamb which represents the Lamb of God that takes away the sins of the world.
Jesus cursed the fig tree (Adam’s attempt to humanly take care or cover sin) - God had the better way, the shedding of blood.
So we have words from God, a promise, a blood covenant that was fulfilled in Jesus. You don’t have to use the word “covenant” for there to be one.
