In this powerful message from Genesis 4:9-10, we explore the confrontation between God and Cain after the murder of Abel. Discover the profound significance of the first mention of blood in Scripture — how Abel's blood cries out for justice from the ground, and why this points forward to the ultimate blood that "speaks a better word" (Hebrews 12:24). We unpack: The life-giving reality of blood in God's redemptive plan How sin escalates and multiplies (one sin opens the door for another) The covenantal war between the seed of the woman and the seed of the serpent Why Christ's blood fulfills what Abel's sacrifice anticipated and satisfies the justice Abel's murder demanded This is foundational gospel truth: blood is not just symbolic — it is life itself, and Jesus' blood secures both justice and mercy. Perfect for anyone seeking deeper understanding of atonement, penal substitution, and the continuing story of redemption from Genesis to the cross. If you're new here, this sermon is part of a series walking slowly through the book of Genesis — life after Eden, the intensification of the fall, and God's sovereign grace.
