In Genesis 4:1–16, Chris unpacks the first act of worship outside the garden and the fracture between two brothers. Why does God “regard” Abel’s offering and not Cain’s—and what does that reveal about trust, envy, and the myth of limited favor? We explore sin “crouching at the door,” the mark of Cain as a sign of mercy, and the call to be our brother’s keeper. The episode ends by pointing to the better word of Jesus’ blood—ending rivalry and inviting us to trust God’s abundant grace east of Eden.
