The amazing aspect of the story is not murder, it is not about jealousy, and it is not about right sacrifices and offerings to God. Instead it is about our God. Cain murders Abel. God does not kill Cain. Cain is angry and thirsts for blood. God is angry but forgives. God not only forgives but goes even farther to putting a mark on Cain in order to protect him from the revenge of the human community.
Right here at the beginning of our bibles is this phenomenal story about forgiveness, peace, and the way forward for fallen humanity. Why don't we pay more attention to it?
