Sermon Synopsis 8.3.25
Delivered by Bishop Walker
1 Samuel 17:45-51
New International Version
45 David said to the Philistine, “You come against me with sword and spear and javelin, but I come against you in the name of the Lord Almighty, the God of the armies of Israel, whom you have defied. 46 This day the Lord will deliver you into my hands, and I’ll strike you down and cut off your head. This very day I will give the carcasses of the Philistine army to the birds and the wild animals, and the whole world will know that there is a God in Israel. 47 All those gathered here will know that it is not by sword or spear that the Lord saves; for the battle is the Lord’s, and he will give all of you into our hands.”
48 As the Philistine moved closer to attack him, David ran quickly toward the battle line to meet him. 49 Reaching into his bag and taking out a stone, he slung it and struck the Philistine on the forehead. The stone sank into his forehead, and he fell facedown on the ground.
50 So David triumphed over the Philistine with a sling and a stone; without a sword in his hand he struck down the Philistine and killed him.
51 David ran and stood over him. He took hold of the Philistine’s sword and drew it from the sheath. After he killed him, he cut off his head with the sword.
When the Philistines saw that their hero was dead, they turned and ran.
I. Introduction
Today I want to talk to you from the subject: “Use the Rock You’ve Got.”
There comes a moment in every believer’s life when you’re faced with a challenge that exceeds your strength, your network, even your understanding. It’s in those moments the enemy tries to convince you: You’re not enough.
That’s when fear creeps in and whispers in your ear, leaning on your insecurities, telling you that “You don’t have what it takes”.
But I came today to tell you succinctly, You’ve got this! Not because of what you have in the natural—but because of what God has given you in the Spirit.
What God started in you, He will perform until the day of Jesus Christ.
The story of David and Goliath reminds us that God specializes in using small things to accomplish what seems impossible.
Yes, David slayed Goliath—but this is also the story of a king being released. David was in divine alignment with the assignment God had on his life. He stepped onto the battlefield when others were afraid to face it.
He didn’t step up with bravado. He stepped up with belief.
This wasn’t just about defeating a giant. It was about God revealing His power through someone who dared to believe.
So whatever you’re facing—whatever giant you brought here today, whether it be:
- A health crisis?
- Financial pressure?
- Relational challenges?
- Spiritual warfare?
Know That giant is about to fall!
It will fall, because God will show you that you already have everything you need.
You just need to learn how to use the rock you’ve got!
Before we dive into the battle, let’s understand the historical and cultural context that gives this moment its full weight.
Israel was in transition. They had been ruled by judges—temporary leaders raised up by God during times of national crisis. But the people grew weary and cried out for a king.
God warned them: It’s not time yet. But they pressed. So, through His permissive will, God allowed them to choose.
They chose Saul—tall, handsome, strong—but lacking obedience and spiritual maturity. His disobedience caused God to reject him. And while Saul was still on the throne, God was preparing David.
David—Was the youngest of eight. Jesse’s son. From Bethlehem. His brothers were in the military, but David was tending sheep in obscurity.
David had already been anointed by the prophet Samuel—but in secret.
See, God will anoint you in one season and release you in another.
Don’t get frustrated just because you’re not being used yet. It may not be time yet.
You don’t need the title to be anointed.
You don’t need the position to be powerful.
David brought his brothers food—he wasn’t on the battlefield, he was serving on the sidelines.
Meanwhile, the Philistines—the coastal enemies of Israel—stood in opposition.
They were polytheistic, technologically advanced, and persistent in their resistance. They had five major cities:
Ashdod, Ashkelon, Ekron, Gaza, and Gath.
Gath—the place Goliath was from.
Goliath wasn’t just a man—he was a trained warrior.
- Nine feet tall.
- Head-to-toe armor.
- A spear like a weaver’s beam.
And standing before him?
- A 4-foot-5 shepherd boy.
- No armor.
- No sword.
- Just a sling.
- And five smooth stones.
But David came not with fear, but with faith.
Goliath mocked him. But David declared: “You come to me with sword and spear—but I come to you in the name of the Lord Almighty!”
II. Recognize the Resources You’ve Received
God will never send you into battle without giving you what you need.
Those smooth stones may not have looked like much—but they were enough in God’s hands.
We often underestimate the power of what God has given us because it doesn’t look like what others have. But what you carry may be unconventional—and still exactly what’s needed for victory.
A. Acknowledge That God Has Equipped You
Every hidden battle, every private victory—was God preparing you.
David’s battles in the pasture with lions and bears? That was training ground.
In other words, your private pain was public preparation.
B. Understand That What You Have Is Enough
When you place what you have in God’s hands, miracles happen.
The slingshot may look common—but in God’s hands, it becomes catalytic.
David didn’t just see stones—he saw victory.
When you release what you’ve got, Heaven backs you up.
III. Rely on the Rock’s Reliability
David didn’t place his confidence in his aim—he placed it in God. He said “I come to you in the name of the Lord Almighty.” That changed the whole battle.
Goliath thought he was facing a boy, the was facing a believer.
Touch your neighbor and tell them: You can’t treat me any kind of way — I’m a believer!
When you use the rock you’ve got, you can say: “You may come to me with sickness, with slander, with shame—but I come to you in the name of the Most High God!”
A. Trust That God’s Strength Is Unshakable
I know what it’s like to say, Why me, Lord?
Why the eighth son? Why the one that’s been overlooked the whole time (David)?
The answer is, because God knew: You were the one who wouldn’t flinch.
You’re tired—but God says: Have you not known? Have you not heard? The Everlasting God never grows weary.
They that wait upon the Lord shall renew their strength!
B. Remember: The Rock Will Never Fail
Psalm 18:2—“The Lord is my rock, my fortress, and my deliverer.”
When everything shakes—God is still solid.
The rock you stand on is stronger than the giants you face.
IV. Refuse to Retreat from Resistance
Goliath moved forward, but David didn’t flinch.
Everyone else stayed back, David stepped forward.
Battle lines are drawn to expose what’s in you.
Saul had the title—but David had the anointing.
And only the anointed cross battle lines.
A. Stand Firm with Unwavering Confidence
This isn’t arrogance—it’s divine assurance.
Faith is not the absence of fear—it’s obedience in the face of fear.
B. Don’t Let Fear Dictate Your Actions
Fear will paralyze you at the runway of destiny.
But I hear the Spirit saying: “Oh no, I’ve flown through worse.”
And if God brought you to it, He’s equipped to fly you through it.
V. Rejoice in the Results of Your Resolve
Now here it is—David used one rock. He didn’t need all five.
He took what looked small and released it with faith.
And Goliath—fully armored—had one weak spot: his forehead and the rock found it.
Because the power wasn’t in the stone—it was in the Spirit behind it.
David then used Goliath’s own sword—just like he prophesied—to cut off his head.
Don’t shout over knocked-down giants still breathing.
In this season, it’s not just about knockdowns—it’s about cutoffs.
- Cut off fear.
- Cut off shame.
- Cut off toxic relationships.
- Cut off everything that says you’re not enough.
A. Acknowledge God’s Faithfulness in the Fight
David stood over Goliath—foot on his neck.
That 9-foot-tall giant was now under the feet of the shepherd boy, not because of David’s strength, but because of God’s rock.
Closing Charge
Stand up. Grab somebody by the hand.
Tell them: You didn’t realize—you’re number 8!
Rejected by man—but chosen by God.
Tell them: “Use the rock you’ve got!”
And give God a praise like every giant in your life is already falling!
