God knew that Cain had murdered his brother when he asked him, “Where is your brother Abel?”
Cain lied, “I don’t know. Am I my brother’s keeper?” In other words, I am not responsible for my brother, you are, and you don’t even know where he is?
The last time God judged humanities sin he cursed the ground not the man. This time God cursed the man. Adam was not innocent, but he had been encouraged to satisfy his evil inclinations. Cain was worse than his father. No one tempted him.
Cain was jealous, angry, a liar and a murderer yet thought an offering entitled him to God’s favor. When God could not be manipulated, Cain killed an innocent man. Why did Cain take out his anger with God on a bystander who had done nothing wrong?
Cain could have invited Abel to take a walk in the field so he could learn how to have faith in God. If he had loved his little brother, he could have possessed what his little brother had. God’s favor.
Adam’s sin complicated life for everyone because God cursed the ground to produce thorns and thistles. Cain’s sin complicated his own life. The ground would no longer yield crops for Cain, causing his farming business to fail. Then he would wander from place to place seeking rest and never find it. He would never find rest because he was not a peace with God.
Instead of remorse for destroying his brother and causing pain to his parents Cain cries foul, “My punishment is more than I can bear. Today you are driving me from the land, and I will be hidden from your presence; I will be a restless wanderer on the earth, and whoever finds me will kill me.”
The only person Cain is concerned about is Cain. My punishment is too hard. I will lose my farm. I will lose your presence. I will not have rest. Someone will kill me. The most interesting item on this list of complaints is Cain’s desire to remain in the presence of God.
Cain had a relationship with God. He wanted the presence of God, but he had not learned how to love God. Cain saw evil in God. He perceived God’s favor of Abel as favoritism, but it wasn’t. God loved Cain and sought to reconcile with him. He told him how to obtain what he wanted – master your sin. God would have helped him. Instead, Cain allowed sin to rule his life and killed his brother. He was driven from the presence of God because his heart did not belong to God.
“You belong to your father, the devil, and you want to carry out your father’s desires. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies.”
