Genesis 4
Im going to be honest,
This chapter has completel got me confused. Im looking for clarity or answer and im not seeming to find it. Maybe later it will come... But here's my delima.
Im gonna go ahead and type out verses 2-7 and explain....

(talking about Eves first 2 sons)
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. So Cain was very angry and his face fell. The Lord said to Cain " Why are you angry? And why has your face fallen? If you do well, will you not be accepted? And if you do not do well, sin is crouching at the door. Its desires is for you, but you must rule over it."

Im reading it over and over AND OVER and... i feel like ive almost got it,
but i dont.

Why did God Disregard Cain's offering?
Abel was a keeper of sheep... so he brought to the Lord as an offering the firstborn of the flock and brought their fat portions.
Cain was a worker of the ground..... so he brought to the Lord an offering of the fruit of the ground.

Im stumped as to why the Lord Regarded Abels offering but not Cains.
I can see in my mind that back then if I had the option of Fruit or Firstborn of the sheep for an offering to the Lord I would probably choose sheep,
but then again if I was a worker of the ground, like Cain, I would probably give my offering to the Lord in this way.. of what I did for a living. With my best effort put forth.

so, I start to think, was Cain being lazy with his work?
It did say that IN THE COURSE OF TIME Cain brought his offering....
Could Cain had made a better attemp or was he really trying? Thats where Im stuck.

But here's what i do get..
Right after that the Lord made this statement...
Why are you angry? And why has your face fallen? If you do well, will you not be accepted? And if you do not do well, sin is crouching at the door. Its desires is for you, but you must rule over it."

God loved Cain...Right here God was giving Cain another chance. Even though I dont understand yet why God did not regard Cains offering I do know that God encouraged him that if he "did well", his offering would be accepted.
Maybe that is what it is, that God simply wanted Cain to put his heart into what he did and present it to the Lord with a right heart. To find joy in the work of the Lord.
I find it interesting that after God encourages Cain, he also warns him. He tells Cain that Sin is crouching at his door if he does not do well.

this makes me draw the conclusion that when we are not fully satisfied with the Lord or giving back to the Lord what is already his in the first place, that sin is closer to us than we think... creeping in like a theif in the night, ready to make its mark on your life
I truely believe Cain could have avoided the sin of killing his brother if he would have only listened to this warning.
I think sin manifest itself and the very thing we think we would never do ends up being the very thing we do and we wonder how did it get that far. So much evil happens in the world and we wonder how a human could ever do these things.. But if you think about it, living a life that is seperate from God, sin will sit in the hearts and manifests itself.. growing like a snowball effect. Where one seamingly small emotion can lead to sin which leads to another taht justifies another that leads to the wickedness of mans heart...

Sin was crounching at Cains door, because he rejected to do well, to try again. He gave up, and let his jealousy over his brother take over him like a snowball affect.

Sins desires are for you, but you MUST rule over it.
These were Gods words.

ANY FEEDBACK?

Its November 3 and I am mentally drained.
