S – The Lord had regard for Abel and his offering, ⁵ but he did not have regard for Cain and his offering. Cain was furious, and he looked despondent. 

Genesis 4:4–5 CSB

O – C ommentary:

Abel, however, seems to be lined up with man’s original purpose, to have dominion over life (cf. 1:28); he kept flocks. These coincidental descriptions are enhanced with their actions in worship. Abel went out of his way to please God (which meant he had faith in God, Heb. 11:6), whereas Cain was simply discharging a duty. Abel’s actions were righteous, whereas Cain’s were evil (1 John 3:12). These two types of people are still present.

Cain’s lack of faith shows up in his response to God’s rejection of his offering of fruit (Gen. 4:5). Rather than being concerned about remedying the situation and pleasing God, he was very angry.

4:6–7. Cain was so angry he would not be talked out of his sin—even by God

“Genesis,” in The Bible Knowledge Commentary: An Exposition of the Scriptures

A – Early in creation, comparison to others and anger are revealed in human nature. It is imperative that both are conquered.  Cain wasn’t focused on his own relationship with God and how to make that better.  His anger was too far gone for even God to change.  We must surrender and yield our hearts and emotions to God instead of seeking our own will.

R – Heavenly Father, you are holy and just.  Help us to see your will and plans as best for us.  Let us learn to celebrate others and be angry in a healthy way.  Your will is what is best for us.  We invite your Holy Spirit to help us follow your direction.
