Yes, good question on Cain's "first fruits"
I could see if this was a sacrifice for "sin" but, how do we even know that?
Hebrews 11:4-6:
By faith Abel offered to God a better sacrifice than Cain, through which he obtained the testimony that he was righteous, God testifying about his gifts, and through faith, though he is dead, he still speaks….And without faith it is impossible to please Him, for he who comes to God must believe that He is and that He is a rewarder of those who seek Him.
I tend to believe it was Cains lack of true faith in his heart. :)
You are on the right track my sister.
“
By faith Abel offered to God a more excellent sacrifice than Cain, through which he obtained witness that he was righteous, God testifying of his gifts; and through it he being dead still speaks.” (
Heb 11:4 NKJV)
“
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. And through his faith, though he died, he still speaks.” (
Heb 11:4 ESV)
From the foregoing text it is apparent that Abel’s offering was acceptable because of his faith.
Perhaps the following extract from “
Studies in the Book of Hebrews” might prove useful.
"
Faith comes by hearing, and hearing by the word of God," Paul tells us. (
Rom 10:17)
This would indicate that Abel received information from God concerning the kind of sacrifice he should offer. If it had simply been a case of each of the brothers offering to the LORD what they had on hand to give, Abel's faith would not have entered into the offering any more than Cain's.
Seldom does the Bible give all the details of any occurrence and, although no mention is made of it, we think it is quite possible that Abel was informed by the LORD that he wished a flesh and blood offering. His obedience demonstrated his faith, proving that he was righteous.
The text says that Abel was “
righteous.” The same Greek word is used here as when Paul wrote, "
There is none righteous, no, not one." (
Rom 3:10) In this latter statement, however, absolute righteousness, or perfection, is referred to, whereas the righteousness of Abel was merely his
heart condition which was demonstrated by his faith and obedience. It is essentially the same thought as that contained in the reference to Abraham's justification by faith.
A close analysis reveals the great importance God attaches to faith in him and in his arrangements and promises. Had Adam possessed true faith and confidence in God he would not have transgressed his law. While Adam's descendants have lost perfection and life because of his sin, those such as Abel, Abraham, and others who, despite their imperfections, did believe God, proved their worthiness of his favor and friendship.
Such faith-righteousness is properly and scripturally described as justification.
During the Gospel Age those who possess such a faith, AND demonstrate it (put it in action)
by full consecration to the LORD, are justified to life through the merit of the shed blood of Christ.
This is in order that they might present their bodies living and acceptable sacrifices to God (
Rom 12:1),
and thus share in the sacrificial work of this age. However, during the preceding ages there was no opportunity to share in the "
better sacrifices." (
Heb 9:23) The imputation of the blood of Christ was not needed to give a standing of life to God's servants; but their faith was no less vital because of this, nor were they less pleasing to God. It is simply that he dealt with them differently than he does with those in this age who possess a justifying faith.
In passing, it is well to give thought as to why God was pleased with the flesh and blood sacrifice offered by Abel.
It was evidently because it pointed forward to the sacrifice of Christ, "
the Lamb of God, which takes away the sin of the world." (
John 1:29) When condemning our first parents to death, God made the statement that
the seed of the woman would bruise the serpent's head. (
Gen 3:15) This was a veiled promise of future deliverance from the result of original sin. But for this to be possible there would need to be remission of sin, so God began to illustrate that this was to be accomplished by the shedding of blood (
the first apparent illustration of this being His providing skins to cover the nakedness of Adam and Eve, this required the sacrifice of a life). As his plan of redemption unfolds, it comes to light that it was to be through the shed blood of his own beloved Son.”
