And in the process of time it came to pass that Cain brought an offering of the fruit of the ground to the LORD. Abel also brought of the firstborn of his flock and of their fat. And the LORD respected Abel and his offering, but He did not respect Cain and his offering. And Cain was very angry, and his countenance fell.
So the LORD said to Cain, “Why are you angry? And why has your countenance fallen? If you do well, will you not be accepted? And if you do not do well, sin lies at the door. And its desire is for you, but you should rule over it.”
Now 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 killed him. Gen 4:3-8
When Cain felt he was rejected, Anger was there to comfort him.
Anger told him that God was at fault; that all God had to do was accept his offering and everything would have been okay.
Anger said, “If Abel hadn’t been so uppity and brought his little lamb, then things would have turned out different.”
Anger was invited to live within Cain and feed him poison.
Cain didn’t see this; he couldn’t because anger blinds us to reason.
Anger suppresses repentance and forgiveness.
Anger blames others.
Anger becomes a dictator, a tyrannical ruler with no rationale or sensibility.
A person cannot think straight through clenched teeth and a balled up fist.
It does not say how long Cain was with Anger, but they talked every day.
Anger festered up in him, poisoning the love he had for his brother.
Cain’s mind raced with how to resolve the problem.
He couldn’t get rid of God and Anger would not let him repent.
He wouldn’t bring another offering because Anger reminded him of God’s words; “If you do well, will you not be accepted?”
Anger told him he had already done his very best and was rejected; there was nothing more to give.
Anger said that the problem is with Abel; he is to blame.
Get rid of Abel and get rid of the problem.
When only one person is offering to God, then God would have to accept it.
Cain did not know that Anger is self-righteous and hypocritical.
Thus Cain listened to Anger and killed his own brother.
Anger told Cain he was right; that he was powerful enough to make his own way.
When God asked, “Where is Abel your brother?” (Gen 4:9), Anger answered, “Am I my brother’s keeper?” Gen 4:9
Anger led Cain far, far away from God; and Anger became the tutor for Cain’s entire family for generation after generation.

So what is Anger telling you today?
Whatever it is, don’t listen to Anger!
