I always thought that the salvation message didn’t show up in the Bible until the book of Matthew in the New Testament, but here in the 3rd chapter of Genesis we see the plan for the salvation of mankind unfold.

The plan for the salvation from our sins through Jesus unfolds directly after the fall of mankind caused by the sin of Adam.

¹³ And the Lord God said unto the woman, What is this that thou hast done? And the woman said, The serpent beguiled me, and I did eat.

¹⁴ And the Lord God said unto the serpent, Because thou hast done this, thou art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life:

The Lord God asked Adam what he did, and he asked Eve what she did, he did not ask the snake. The snake is Satan, the father of lies, there is never any use to ask for information from a liar, you won’t get the truth, just more lies. Also, God knows everything. He already knew exactly what happened and who did and said what. He asked to give each of them a chance to confess. Right off the bat, Adam first blamed Eve, then blamed God for giving Eve to him. Adam and Eve were naked before they ate the fruit, they were just unaware of it until they ate the forbidden fruit from the tree of the Knowledge of Good and Evil. The sin they committed was disobedience and as a result of eating the fruit from this tree, they lost their innocence. They were no longer innocently in the garden naked and free, but they were now aware of their nakedness and filled with shame…as a result they hid from God. Eating the tree they did find out the difference between the innocent life they had before and the one they had after where they could no longer present themselves to God without shame and guilt. God, being the merciful and loving God that he is, had a plan. His plan was to reconcile man to himself by the blood of his only-begotten son, who would be born of a woman, go to the cross, die for the sins of mankind, defeat the death that held us, then rose again from the dead.

¹⁵ And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.

Jesus was born of a woman and crushed the head of Satan when he died on the cross and defeated Satan’s plan to kill all of us with death and take us to hell and later the lake of fire. Once a person lands in the lake of fire there is no hope for them, they will be there forever…separated from God. Our human minds only know time the way we measure it. If a person enters the Lake of Fire they will know that there is not another chance for them to accept Jesus…. they know they will never leave….and they know they will never be in the presence of God or experience the joy of knowing God. Every pleasure of life will be gone, there will be no relief or an end in sight that you can pin your hopes on. Just eternal torment. Satan wants to take as many of us humans as he can to final judgement and the lake of fire. So why really? Because he knows how much God loves us and how precious we are to God. He wants to rob God of his children. As much as we as Christians want to be right with God and to spend eternity with him in heaven, God wants it even more. He wants it so much, he sent his only son to die for us to reconcile us to him. We humans fall in and out of love all the time, but God doesn’t…. he simply loves us all the time, never changing. Imagine a time when you were absolutely head over heels in love with someone…. God’s love for us is infinitely greater than that. Satan doesn’t want us to know how much God loves us, so one of his biggest lies he tells us as believers is that God’s love is conditional on perfect behavior from us. The devil already knows we will never be sinless, so this lie that God’s love is conditional on works sets us up to feel like we failed God and there is no hope for us. When we are trying to work our way, we will always fail, and we will miss the gift of God, his son Jesus and the blood bought salvation and reconciliation to God that he gave us.
So there in the garden of Eden with Adam and Eve who had now sinned , God, not willing to lose fellowship with mankind that he loves so much, made a plan to send his son Jesus to die and reconcile us to God with his blood.

¹⁶ Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire shall be to thy husband, and he shall rule over thee.

¹⁷ And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life;

¹⁸ Thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field;

¹⁹ In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.

²⁰ And Adam called his wife’s name Eve; because she was the mother of all living.

²¹ Unto Adam also and to his wife did the Lord God make coats of skins, and clothed them.

²² And 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:

God was talking to Jesus.

²³ Therefore the Lord God sent him forth from the garden of Eden, to till the ground from whence he was taken.

²⁴ So 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.
