This week, in our sermon series through the book of Genesis, we encountered the story of Cain and Abel. This story of feuding brothers offers us insights into worship, sin, and God’s grace. I’m going to explore a bit about Genesis 4 here. Hopefully, showing how it reveals the heart of our relationship with God and each other, and how it points us to the ultimate sacrifice of Jesus Christ.
Genesis: The Prologue to God’s Law
Genesis isn’t just a history of early humanity; it’s the historical prologue to the Torah, the first five books of the Bible. This context shapes our understanding of Genesis, where we see the commandments lived out in story form. The first commandment, “You shall have no other gods before me,” and the last, “You shall not covet,” are deeply connected. St. Paul teaches that coveting is idolatry, choosing self over God. This sin, first seen in Adam and Eve’s grasping for what wasn’t theirs, sets the stage for Cain and Abel.
The Original Sin and Its Consequences
In our sermon last week, we discussed how original sin, coveting what God forbids, bends our hearts against our Creator. This rebellion, choosing ourselves as God, leads to slavery, not freedom. Genesis 4 shows this slavery to sin unfolding through Cain and Abel, moving from idolatry and coveting to the heart of the commandments: “You shall not murder.” As St. James notes, coveting fuels conflict and, ultimately, murder. This dark truth reveals our need for God’s forgiveness in Jesus Christ.
Cain and Abel: Two Offerings, Two Hearts
In Genesis 4, Eve, trusting God’s promise of redemption, names her son Cain, acknowledging him as a gift from God. Cain, a worker of the ground, and Abel, a keeper of sheep, both bring offerings to God. But their offerings differ starkly. Cain offers “some fruit of the ground,” described plainly, without care. Abel, however, offers the “firstborn of his flock and their fat portions,” the best he has, given with faith and gratitude.
This contrast is crucial. Abel’s offering reflects a heart free to give, trusting God as his provider. Cain’s offering, lacking heart, reveals a grasping spirit, clinging to what he sees as his own. The book of Hebrews confirms Abel’s sacrifice was accepted because it was offered in faith. God desires our first and best, our time, talent, and treasure, given freely, not reluctantly.
The Downcast Face of Cain
When God accepts Abel’s offering but not Cain’s, Cain’s face falls in anger. This “spiritual face,” is a vision of our disposition toward God. Cain’s anger stems from wanting acceptance on his terms, not God’s. This leads to the tragic murder of Abel, the closest image of God Cain could attack. Jesus teaches that anger in our hearts is akin to murder (Matthew 5:21-22). We’re all in this sense “Cains,” harboring resentment when we don’t get our way, revealing our rebellion against God.
The Power of Confession and Forgiveness
God confronts Cain, asking, “Why is your face downcast? If you do what’s right, will you not be accepted?” The law acts as a mirror, showing our angry, downcast hearts. Yet, confession offers freedom. Admitting our wrongs to God aligns us with His mercy and forgiveness. Remember, when you repent you are forgiven. If your guilt lingers, seek a pastor’s counsel to hear God’s absolution face-to-face. That is one of the reasons I am here, not just to preach to you every Sunday and administer the sacrament of the alter, but to assure you of God’s forgiveness through Jesus. You see, Jesus has arranged for us to be forgiven and healed, and we all need to be reminded of that from time to time.
Abel’s Blood and Jesus’ Better Word
Abel’s blood cries out from the ground. Sin has consequences: judgment and exile. But the book of Hebrews tells us Jesus’ blood speaks a better word. Jesus, the firstborn of creation, offered Himself freely, bearing the weight of God’s glory. His sacrifice transforms us from grasping Cains to open-handed givers like Him. At the Lord’s Table, we receive His body and blood, a “blood transfusion” that replaces our death with His life.
Choosing Acceptable Worship
Cain and Abel present a choice: unacceptable worship, demanding God accept us on our terms, or acceptable worship, embodied in Jesus. In Him, we’re forgiven for our hatred toward God and others. The Spirit transforms us to live freely, giving ourselves in love and devotion to our Father. Why cling to the old self when Christ offers a new self, made in His image?
As we approach the Christ’s altar, we receive His life, moving us from forgiveness to transformation. May God complete this good work in us through Jesus Christ. Amen.
