Summary: These both knew about God, they had no problem with wondering whether God was real or not, they both knew what God required concerning sacrifices, which was that the sacrifice of an innocent animal must shed its blood to cover their sins, and yet Cain
Hebrews 11:1–4 CAIN & ABEL 9–17–11
Every one and every where in the world, all that are alive today and that has ever lived are like one of these two individuals, we are either saved or lost, Christians or not Christians, believers or not believers, all of us are either as Abel or as Cain when it comes to our position with God.
These both knew about God, they had no problem with wondering whether God was real or not, they both knew what God required concerning sacrifices, which was that the sacrifice of an innocent animal must shed its blood to cover their sins.
God is Holy and He will not tolerate sin in His presents that is why He provided His Only Begotten Son to be sin for us, Jesus was Gods Sacrificial Lamb, God has not changed, none at all.
2 Corinthians 5:21 For He [God the Father] hath made Him [God the Son] to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
Hebrews 9:22––without shedding of blood is no remission. Leviticus 17:11 For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul.
How do we know that Cain & Abel both understood the requirements of God?
Genesis 3:21 Unto Adam also and to his wife did the LORD God make coats of skins, and clothed them.
Before the skins could be provided for a covering for Adam and Eve, an animal had to be killed and blood was shed.
Adam and Eve’s children witnessed many, many times as their parents offered animal sacrifices to God, even before the children were ever born Adam and Eve made sacrificial offerings to God, Abel and Cain were school in this truth all their lives, it was nothing new to them.
An innocent animal, probably a lamb, was killed by God Himself; it shed its innocent blood as it was slain, all because of the sin of our first parents, Adam and Eve.
Genesis 3:20 And Adam called his wife’s name Eve; because she was the mother of all living.
Just think all Adam had to do was obey one simple law “do not eat from that tree” but being human as he was he did not obey, Adam had the most beautiful wife in the world, [being the only one] he really had it made but disobeyed, and ever since then the human race has been born with a terrible blood disease, its called “sin” and the only remedy or cure for this damning disease is to have it washed away in the Precious Blood of the Lamb of God, not covered mind you as was in the Old Testament, but washed away.
This first living sacrifice was afore view of the Sacrificial Lamb of God, the Lord Jesus Christ that was to come.
John 1:29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world. Notice; “sin” singular, that is the damning sin of unbelief, not “sins” as every where we look we can see the results and presents of “sins”.
Another way we know that Cain and Abel knew to offer an animal sacrifice for sin is because we read in Hebrews 11:4 By faith Abel offered unto God a more excellent sacrifice than Cain, by which he obtained witness that he was righteous, God testifying of his gifts: and by it he being dead yet speaketh.
