The First Man Born was a Murderer
Genesis 4:1-7 - Raising Cain:
“And Adam knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man from the LORD. And she again bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground. And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the LORD. And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the LORD had respect unto Abel and to his offering: But unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell. And the LORD said unto Cain, why art thou wroth? and why is thy countenance fallen? If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him. And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.”
In the Garden God showed the way of redemption for even a murderer
When sin entered the world through Adam’s disobedience, God killed the first sacrificial animals and made coats of the skins for Adam and Eve, “Unto Adam also and to his wife did the LORD God make coats of skins, and clothed them” Genesis 3:21. Thus God established the principle of an innocent animal should die to cover man’s sin. This was pictured again in the Passover lamb. The apostle John said of Jesus "The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world." John 1:29
“And almost all things are by the law purged with blood; and without shedding of blood is no remission." Hebrews 9:22.
Jesus the sinless Son of God died to redeem us from the penalty of sin that Adam brought into the world. The perfect for the imperfect. The innocent for the guilty.
