I think I may have posted something on this before. I can't remember. But for those who may have never heard, this is another great shadow of God's grace through Jesus' blood in Genesis.
I e-mailed this to a few people so you may have read this already, but I figured I would post it for anyone who may not have seen it.
Here ya go:
'Now Adam knew Eve is wife, and she conceived and bore Cain, saying, 'I have gotten a man with the help of the LORD.' And again, she bore his brother Abel. Now Abel was a keeper of sheep, and Cain a worker of the ground. In the course of time Cain brought to the LORD an offering of the fruit of the ground, and Abel also brought of the firstborn of his flock and of their fat portions. And the LORD had regard for Abel and his offering, but for Cain and his offering He had no regard.'
Now, I always wondered why God didn't accept Cain's offering but He accepted Abel's. But the book of Hebrews gives us a hint in Hebrews 9:22: 'Without the shedding of blood there is no forgiveness of sins.'
And again in Hebrews 11:4: 'By faith Abel offered to God a more acceptable sacrifice than Cain, through which he was commended as righteous, God commending him by accepting his gifts.'
Now remember that God had told Adam, 'By the sweat of your brow you shall work the ground.'
So we see that Cain was trying to make himself acceptable before God by his own labor. His own works. He probably thought to himself, 'I know God said He wanted blood for the forgiveness of my sins, but that's just too easy. Surely I have to do MY part.'
But his brother Abel simply brought a lamb sacrifice. So we see that Abel BY FAITH, (not by working his butt off) was made righteous before God. Why? Because the blood of the lamb was a picture of the one whom He loved. His Son, Jesus. The only One in whom He is well pleased.
So at judgment day we can either come to the Lord with our works to be judged (All who are under the works of the Law are under a curse.) or Jesus' work on our behalf. You can either be under Law or Grace. It cannot be both. New wine cannot be poured into old wineskins. You cannot mix the old covenant of law with the New Covenant of Grace in Jesus' blood.
What's it gonna be? Works or Jesus? Law or Grace? Unbelief or faith?
Luke 18:17: 'Truly, I say to you, whoever does not receive the kingdom of God like a child shall not enter it.'
