Genesis 3:15

December 8, 2025



Friends,

Last week we saw the reason ‘why’ Jesus came. The ‘why’ question is one an unbelieving world can’t answer. “Why does anything exist? Why is the world like it is? Why did God allow this to happen?” The Bible has those answers.

For years I have taught a personal application of 2 Timothy 3:16. I’m wondering today if we can apply it to God’s story of cosmic redemption also. It reads, “All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness…” If we do, the Bible tells us,

           1 – What is right with the world – teaching

           2 – What is wrong with the world – reproof

           3 – How to make what is wrong, right – correction

           4 – How God will keep it forever right – training in righteousness

           The answer to “why world is like it is,” is Genesis 3:14 and the answer to how God is going to fix it all is Genesis 3:15.

In the interim, we live between the tears of a fallen world, illustrated in Ezra 3 and the tears of a redeemed world, seen in Revelation 21. It’s the difference between

a)    A soldier departing for war

b)    The children returning home for Christmas

c)    A loved one’s funeral

d)    A baby’s birth

e)    Good Friday

f)     Easter Sunday

So, last week’s sermon explained the “why” of Genesis 3:15. This week’s sermon will explain the “how” of that text.

You could go back and find “The View from My Study” from last Monday but I’ll provide you with some of those thoughts and then we’ll look at the text itself.

The verse divides into four movements.

First, God announces that He Himself will place enmity between the serpent and the woman. The word “enmity” means hostility, a deep and ongoing conflict. Humanity had aligned itself with the serpent through unbelief, yet God graciously disrupts that alliance. Salvation begins not with Adam’s repentance but with God’s action. “I will put” is the first ray of mercy in Scripture. And remember, God is the only One Who can truly, “I will.” (I’m thinking of Satan’s five “I will”s in Isaiah 14:12-15.

1.    “I will ascend to heaven”

2.    “I will set my throne on high”

3.    “I will sit on the mount of assembly in the far reaches of the north”

4.    “I will ascend above the heights of the clouds”

5.    “I will make myself like the Most High”

Of course, none of that came to pass. Only God is sovereign. Only God determines history.

Only God can say “I will” with the certainty of it already done!

Second, God expands the conflict beyond the individuals in the garden. All of creation has been corrupted, and all of Adam’s line is contaminated. So this conflict will continue to grow “between your offspring and her offspring.” This introduces two lines running through Scripture. One is marked by rebellion, unbelief, and violence. The other is marked by faith, covenant promise, and righteousness. The story of the Bible follows these two lines as they narrow through Seth, Noah, Abraham, Judah, David, and ultimately the Messiah.

PS – Have you noticed that Peter is a New Testament Judah? I’m thinking of the transformation that we witness between Peter’s denial and Pentecost and 1 & 2 Peter. And I’m thinking of the transformation we witness in Judah from the time he led his brothers to sell Joseph into slavery to when he offered himself as a pledge/substitute for Benjamin. What a glorious gospel friends!

Third, it is true that in the process of redemption, the serpent will “bruise His heel.” The victory will come through suffering. The Redeemer will be wounded, yet His wound will not be final. The serpent will strike, but he will not conquer. The promise looks ahead to a costly victory that will unfold fully in the cross of Christ. This sets the Bible pattern for salvation in judgement, which is a cosmic and personal blueprint.

Fourth, notice that the language shifts from collective to singular. The promise becomes personal: “He shall bruise your head.” A single descendant of the woman will rise to deal the serpent a decisive and fatal blow. Even though Jesus is wounded at Calvary, he nonetheless survives the ordeal in his resurrection, triumphing over the whole curse that began back in Eden. The imagery of crushing a head points to complete defeat. From this point forward, the Old Testament anticipates a Redeemer, a Champion who will undo the serpent’s work. The rest of the Bible is the unfolding and revealing of that plan.

Taken together, Genesis 3:15 introduces the key themes of the gospel: divine initiative, a promised Redeemer, victory through suffering and Jesus’ ultimate reconciliation of all things to himself (Colossians 1:20). Everything else in Scripture grows from this “seed.” This is the beginning of the story of everything.

Now, as the old timers say, “If that don’t light your fire, your wood is wet.” It’s not only shoutin’ time in Heaven, but on earth too, culminating in the voices of unnumbered angels at Jesus’ birth.

So, below these comments you’ll find a general outline for this Sunday’s sermon plus the TRAP devotion for CG leaders to help this word of Christ dwell richly in you throughout the week. As you study and mediate on this passage each day this week, let your imagination run through the pages of Scripture and watch how God works out all the aspects of the birth of Jesus which we celebrate during this Christmas season. It is indeed the most amazing story.

Here's the sermon outline as it stands this Monday morning -

Intro: The first mention of the Gospel is in Genesis 3:15 where God promises a deliverer to fix what is wrong with us and the world, what hurts us and the world. In inexplicable grace, God doesn’t turn his back on a rebellious world but sets a plan in motion to reconcile everything: ‘to restore, with more.’

It all begins with -

First: The Divine Initiative: God Breaks Into Our Ruin - “I will put enmity…” - This is Eden

Second: The Human Line: God Will Act Through the Woman - “…between you and the woman, and between your offspring and her offspring…” - This is the history of OT Israel

Third: The Coming Champion: A Singular Son Will Win the Ultimate Battle - “…He shall bruise your head…” - This is Bethlehem

Fourth: The Wounded Deliverer: Victory Through Suffering - “…and you shall bruise His heel.” - This is the cross and the empty tomb

Fifth: The Gospel Pattern Established in Eden: The Cross Before the Throne – This is our story

Conclusion: The whole Bible story can be told in Genesis 3:15.

1. God Acts – “I will put enmity…”
2. God Chooses – “…between your offspring and her offspring…”
3. God Sends – “He shall bruise your head…”
4. God Wins – “…you shall bruise His heel.”

It’s God’s story. It’s your story. It’s our story. It’s the story of everything.

The Divine Initiative

“I will put enmity…”

Think. Genesis 3:15 opens with the most unexpected phrase in the Bible. “I will put.” The first movement of redemption begins not with Adam’s repentance but with God’s personal action. Humanity chose alliance with the serpent, yet God Himself intrudes to break that alliance, entering into our ruin. This is the first ray of mercy in history. Only God can speak an “I will” that becomes an unbreakable certainty. His initiative is the fountainhead of grace.

Reflect. Consider what this means for the story of Scripture. The serpent made his five “I will” claims in Isaiah 14, yet not one of them came to pass. Only God determines the shape of history. Wow, that will ‘preach’ for your CG members as they apply this to their own lives. When the world falls, God acts. When the heart rebels, God moves toward us. Redemption begins in divine pursuit, not human recovery.

Apply. You may often feel pressure to generate spiritual momentum in your group. Let this phrase steady you. God begins the work in every soul you shepherd. Look for evidence of His initiative among your CG friends this week. Trust that He is already moving before you ever speak on Sunday.

Pray. Father, thank You that salvation begins in Your “I will.” Help me rely on Your initiative and power as I guide others this Sunday. Let my confidence rest in Your grace.

The Human Line

“…between your offspring and her offspring…”

Think. God expands the conflict beyond the serpent and the woman. Two lines now run through Scripture. One line is marked by rebellion and unbelief. The other is marked by faith and covenant promise. The whole Old Testament becomes the story of these two lines narrowing toward the One who will embody all hope. What OT names can you think of who stand at the head of each of these lines or continue them?

Reflect. Ponder how this theme traces through Seth, Noah, Abraham, Judah, David and finally Jesus. The long, winding story of Israel is already present here in seed form. The conflict of the world, the ache of human history, the longing for a king all grow out of this single promise. The “why” of the world’s condition is found in Genesis 3:14. The “how” of God’s restoration is introduced in Genesis 3:15. What a glorious book we have in the Bible, friends!

Apply. As CG leaders, remember that every person you shepherd is shaped by a story larger than their own. Help them see their place in God’s redemptive line. Don’t let them interpret one day or event apart from all else God is doing in them and in the world. Encourage them that their faith, however small, is part of a divine narrative that began in Eden and is fulfilled in Christ.

Pray. Lord, thank You that You weave history through promise. Draw my heart into Your story and, this Sunday, let me help others find their place in it.

The Coming Champion

“He shall bruise your head…”

Think. Here the promise moves from many to one. Many Bible characters have succeeded but all have failed in one way or another. This is why a singular Son is promised. There is only one Hero of the Bible. A divine Champion will arise. Redemption becomes personal. The serpent’s power will be crushed by the offspring of the woman. This is Bethlehem foretold. Every prophecy, every longing, every covenant bends toward this Child.

Reflect. Meditate on how remarkable this is. In the ruins of Eden, God announces Christmas. Before Abraham, Moses or David, God promises a Deliverer who will undo the serpent’s work. The entire Bible grows from this seed. The manger is already glowing with promised hope while Adam and Eve still stand trembling in their shame. Wow, what a story the Bible tells!

Apply. Let this sharpen how you prepare for Sunday. When your CG gathers, you are pointing them toward the Champion who has already won their victory. Think of those who feel defeated or overwhelmed. Lead them to behold Jesus, who overcomes and crushes what they cannot, be it temptation, sin, oppression, etc. Don’t fight alone. Run to Jesus and stand in his victory.

Pray. Jesus, You are the promised Champion. Let my heart rejoice in Your victory and help me lead others to rest deeply in Your triumph.

The Wounded Deliverer

“…and you shall bruise His heel.”

Think. Victory comes through suffering. The serpent will strike. The Redeemer will be wounded, yet the wound will not be final. Here the cross of Golgotha rises on the horizon of Eden. Salvation will unfold through judgment and triumph through injury. The Champion’s heel will be bruised, but the serpent’s head will be crushed. One wound is temporary. The other is final.

Reflect. This is the gospel pattern that shapes the whole Christian life. Resurrection hope always grows out of ‘cruciform’ (cross-shaping) soil. We see this throughout Scripture. We see it in the life of Jesus. We see it in our lives. The cross comes before the throne. The valley comes before the mountain. The ache comes before the song.

Apply. Help your CG members reinterpret their present sufferings in light of this promise. Some of your CG members are bruised in spirit. After all, Christmas can be both exhilarating and depression. Some may feel struck by the world. Remind them that the suffering of Jesus has secured their final healing. No wound endured in faith is wasted. It becomes a place where Christ’s victory is learned. We will weep in Heaven, but tears of joy, and only for a moment!

Pray. Lord Jesus, teach me to see suffering through Your cross. Use my wounds as testimony of Your triumph. Then, strengthen me to shepherd my CG with compassion and hope, pointing everyone to Jesus.

The Gospel Pattern for Our Lives

The Cross Before the Crown

Think. Genesis 3:15 is not merely ancient history. It is the pattern by which God has formed His people throughout history. And he’s still doing it today. God acts. God chooses. God sends. God wins. Our story unfolds within His story. The cosmic war becomes personal as the Spirit applies Christ’s victory to our daily struggles and sanctification.

Reflect. We live between the tears of a fallen world, like Ezra 3, and the tears wiped away in Revelation 21. The ache of departure and the joy of return. The sorrow of Good Friday and the song of Easter morning. Every shadow in our present experience is held within the light of the Redeemer’s finished work.

Apply. As you prepare for Sunday’s gathering, let this week’s meditation draw your heart into worship. Encourage your group to enter the story of Genesis 3:15 with awe. Let them see Christmas as the unfolding of this ancient promise. Lead them to marvel at the God who restores with more.

Pray. Father, unite my heart to the gospel pattern. Let the cross shape my life. Let the resurrection shape my hope. Then, prepare me to lead your people with grace, joy and clarity.

Blessings to you, dear friends, as you study Genesis 3:15 this week. May the Holy Spirit wonderfully apply it to your life so that he can apply it to your CG through you this Sunday.
