Now that sin and death have entered the world, and Adam and Eve are cast out from the garden, sin gets worse. One of their children murders another of their children in cold blood. Many wonder and speculate why the Lord had no regard for Cain’s offering, but it comes down to a matter of the heart and of faith (see 1 John 3:12 and Hebrews 11:4). God, in fact, challenges him to do better. But his nature comes out when he kills his brother because of his jealous heart.
It is proper to note that the Bible (God), as is always the case, does not try to tell us every little detail about everything we would like to know. We can surmise about where Cain’s wife came from. Adam and Eve obviously had more children than just Cain and Abel. But that is our speculation, and is not important to God’s message to us. God has promised that hope will come from Eve’s offspring, and Adam and Eve clearly know what happened between Cain and Abel (v 24). So Seth is born. We will see Seth and Cain’s lines develop as the story continues. Cain’s descendant Lamech will be a worse murderer and his people are attributed with animal breeding, music, metalwork, and more sin. Seth’s descendants seem to be the first to “call upon the name of the Lord” (v 26).
