4 And Adam knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man from the Lord.
2 And she again bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground.
3 And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the Lord.
4 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:
5 But unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell.
6 And the Lord said unto Cain, Why art thou wroth? and why is thy countenance fallen?
7 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.
8 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 text we see that Cain and Abel were bringing their offering to God. Abel brought the 1st of his flocks and Cain brought of the fruit of the ground. Both brought their offerings to God and only one was accepted. That was Abel. Abel gave his best to God. Cain did not. Now, God said to Cain “if thou doest well, shall thy not be accepted”? This was a do over opportunity. Even though Cain did not get it right the 1st time, he was given another chance. But, Cain became angry at Abel, because God did not accept his offering. Ahhh, did not God just give Cain another chance to present is offering? Cain did not see the opportunity to present God with another offering. All he saw was rejection and he saw that Abel was accepted. Cain was jealous. The jealously Cain was so bad, that he killed his own brother. Wow! Yes this is a Wow moment. The opportunity was there to redo the offering and have his offering accepted by God. Instead, he killed his brother. It would have been better if Cain would have given his best in the beginning, then Abel would not have been killed. Not sure how that would have changed Bible history.
We as Christians need to give our best in our tithes and offerings to God. Let’s not look at what someone else gives. Let’s look at ourselves and our relationship with God. If our tithes and offering moves us, surely it will move God.
