In this message drawn from 1 Samuel 17, elder J.M Musungayi (Momentum) returns to David's words in the face of Goliath: "Let no one's heart fail because of him." He shows how the real battle begins in the mouth, in the eyes, and in identity. A word that meets you right where a giant stands before you today.
Introduction
You may have walked in today with a giant standing in front of you. A diagnosis that freezes you in place. A residency permit that's stuck. A project that never comes together. A couple unable to conceive. An administrative issue dragging on. And without realizing it, you've settled into discouragement. You've started giving up, going quiet, giving ground.
The message preached from 1 Samuel 17 meets you exactly there. For forty days, the army of Israel endured Goliath's taunts. No one moved. King Saul himself had inwardly given up. Then a young shepherd arrives and speaks these words: "Let no one's heart fail because of him." That young man is David. And what he brings isn't, first of all, a sling. It's courage, a confession, an identity, and a secret life with God.
This message isn't a catechism lesson on a story you've known since childhood. It's a mirror held up to your current situation. David's God is your God. The Goliath you're facing is nothing but an uncircumcised man. And your discouragement isn't your fate.
Outline of the Message
1. Israel Wanted to Be "Like" Instead of Being "With"
Coming out of Egypt, Israel walked with its God. The sea parted. The wall of Jericho fell. The nations trembled. But little by little, a feeling took hold: no longer to be with, but to be like. Like the other nations. With a visible, tangible, imposing king.
God then gives them Saul. The description speaks for itself: "a mighty man of valor... a son whose name was Saul, a handsome young man. There was not a more handsome person than he among the people of Israel. From his shoulders upward he was taller than any of the people" (1 Samuel 9:1-2). A king chosen by human standards. Tall, handsome, strong. The king who's reassuring because he can be seen.
Your household is boiling over, your work is getting complicated, your relationships are strained. And you catch yourself looking sideways: that couple, that career, that family. You no longer want to be with God, you want to be like someone else. But God made you unique. There's no one like you on this planet. No one who prays like you, who speaks like you, who carries the grace God has placed in you. Comparison is already the doorway to discouragement.
2. The Enemy Changes Strategy and Plays on Appearances
Saul had already defeated the Philistines before. Goliath knew Saul. But the enemy never admits defeat: "Your adversary the devil prowls around like a roaring lion" (1 Peter 5:8). Facing Jesus himself, he shifted his temptation three times in the wilderness before he went on to enter Peter. If he didn't get you here, he'll try somewhere else.
This time, the Philistines change their approach. They play on appearances. Goliath comes out of the camp, six cubits tall, wearing armor weighing 5,000 shekels, carrying a spear weighing 600 shekels. Appearance crushes people before the fight even begins. And Israel, which actually had its own giant in the person of Saul, can now see nothing but Goliath.
Your problem also plays on appearances. What's rational, what's tangible, what jumps out at you first thing in the morning. And your own giant grows bigger every day because you're looking at it more than you're looking at your God.
3. Discouragement: Forty Days of Taunts on Your Own Territory
The Philistines had entered the territory of Judah. Your ground. Your home. And for forty days, morning and evening, Goliath insulted the army of the living God. "When Saul and all Israel heard these words of the Philistine, they were dismayed and greatly afraid" (1 Samuel 17:11).
Discouragement is a feeling that settles in because of what you've been through, and that pushes you to give everything up. To give up what you could still do. Forty days is more than a month of erosion. The soldiers no longer looked at their weapons. Their spears meant nothing to them anymore. Every time Goliath appeared, they retreated.
The king himself, who should have been the supreme commander of the armies, began handing off his power. Looking for someone to reward. Passing the responsibility along. That's the sign that the giant has already won on the inside before ever touching you on the outside.
4. David Arrives With What the Army Is Missing: Courage
A young man arrives at the front. Not a soldier. Not a captain. Not a colonel. A shepherd. His resume fits in two lines: keeper of his father's sheep, killer of a lion and a bear in secret. He didn't have a YouTube channel to broadcast his exploits. He kept it all in his heart.
His first move is a diagnosis: what this army is missing is courage. "Let no one's heart fail because of him. Your servant will go and fight with this Philistine" (1 Samuel 17:32).
Courage is something God does not produce in your place. He asks it of you. To Joshua, he doesn't say "I'm giving you courage," he says: "Be strong and courageous" (Joshua 1:9). To Gideon, hiding in the winepress secretly threshing wheat, the angel says: "The Lord is with you, O mighty man of valor!" (Judges 6:12). The strength was already there. Courage was what was missing.
5. Confession: Speaking to God Instead of Speaking About the Problem
David didn't stay silent. While he was tending his sheep, he had already confessed something to God: "By this I know that you delight in me, that my enemy will not shout in triumph over me" (Psalm 41:12, in the spirit of the text). That word prepared his victory long before Goliath.
God listens to everything that comes out of your mouth. Not just your Sunday prayer. "I will do to you the very things I heard you say" (Numbers 14:28). "If you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved" (Romans 10:9).
Saul talks about Goliath. David talks about God. That's where the difference begins. Today, what is your mouth full of? The problem, or the God who solves the problem? The more you confess victory, the closer you draw God to you. The more you confess defeat, the further you push him away.
6. The Covenant and the Invisible Perspective
Where the others see a giant, David sees an uncircumcised man. A man with no covenant with God. Two different ways of looking at the same scene. "Do not be conformed to this world, but be transformed by the renewal of your mind" (Romans 12:2).
David relied on the covenant. Today, you have an even greater covenant: the blood of Jesus. "He disarmed the rulers and authorities and put them to open shame, by triumphing over them in him" (Colossians 2:15).
"We look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal" (2 Corinthians 4:18). When Lazarus was dead, Jesus said: "Our friend sleeps." He was already seeing the resurrection. The others could smell the decay.
7. Your Identity: Refuse the Armor That Isn't Yours
King Saul also tries to discourage David. He summons him not to send him into battle, but to remind him that he's just a boy, and that Goliath has been a warrior since his youth. Around you too, there are kings, experts, know it alls who will have their say. Don't listen to them more than you listen to the word of God.
Then Saul dresses David in his own armor. It's impressive. It's reassuring. But it doesn't fit him. David takes it off: "I cannot go with these, for I have not tested them" (1 Samuel 17:39). He goes back to his shepherd's clothes, his bag, his sling.
Keep your identity. In Christ, you have an identity the devil cannot touch as long as you're wearing it. Don't disguise yourself as something else to please people. When you try to be someone else to face your giant, you end up walking like a cripple in armor that's much too big for you.
8. The Five Stones in Secret
On the battlefield, David picks up five stones. No one sees them. Goliath will never see the other stones hidden in the bag. That's your secret life with God. "But when you pray, go into your room and shut the door and pray to your Father who is in secret" (Matthew 6:6).
Don't fuss over appearances like the Pharisees who prayed on street corners. Cultivate intimacy instead. The fasts you keep today, the prayers no one sees, will pay off one day. Goliath thinks he's facing a weak kid with a mere stick. He has no idea about the stones.
And "the angel of the Lord encamps around those who fear him, and delivers them" (Psalm 34:8). Like Elisha's servant, whose eyes were opened to see the army of the Lord surrounding the city (2 Kings 6:15-17), you have no idea what multitude of angels is camped around you while you're changing your tire on the side of the road.
9. Walking or Running: The Speed of Faith
Two movements cross paths: "The Philistine moved forward and came to meet David... David ran quickly toward the battle line to meet the Philistine" (1 Samuel 17:48). One walks, the other runs. Where pagans do less, children of God must do more.
If the occultist gets up at midnight, you, a child of God, can "pray without ceasing" (1 Thessalonians 5:17). At work, on the train, while you wait, in the quiet of your heart. And you run, like Paul, "toward the goal for the prize" (Philippians 3:14). Our goal is Jesus.
10. God Pushes Goliath From Behind
The stone strikes Goliath in the forehead and sinks in. Normally, a giant struck in the forehead falls backward. But the Bible is specific: "He fell on his face to the ground" (1 Samuel 17:49). Like Dagon before the ark (1 Samuel 5:3-4). While David was running forward, God was pushing Goliath from behind.
"With God we shall do valiantly; it is he who will tread down our foes" (Psalm 60:14). You never fight alone. While you run in confession, God is at work in the unseen to bring your giant down face first on the ground.
Key Takeaways
- Discouragement begins when you look at your giant more than you look at your God. Forty days of staring at Goliath paralyzed an entire army. Look away.
- Seek to be with God, not like everyone else. Israel lost its way wanting to be like the nations. Your uniqueness is a grace, not a handicap.
- Courage isn't given, it's taken hold of. God waits for you to be strong and to take courage, like Joshua. The strength is already in you.
- Your mouth decides your victory. God acts according to what he hears you say. Speak to God about your problem rather than speaking to everyone else about it.
- Keep your identity and cultivate your secret life. Don't put on someone else's armor. The five stones in your bag are your hidden prayers and fasts. They will pay off on the day of battle.
Personal Application
- What is today's "Goliath" that has been insulting your territory for too long, health, work, paperwork, marriage, children, finances? For how many "days" have you been listening to him without answering back?
- Does your mouth speak more of what the problem shouts at you, or what God has promised you in his Word? If God acted based on your last ten sentences, what would he do?
- What Saul's armor are you trying to wear right now (a borrowed identity, a role that isn't yours, an image to protect), and how is it holding you back in the real fight?
- Where does your secret life with God, your "five stones," stand right now? Hidden prayers, fasting, intimacy. Or are you tending to appearances more than intimacy?
- Who do you talk to about your giant first: God, the people around you, or no one? This week, decide to bring your problem to God before mentioning it to anyone else.

FAQ
What does "not being discouraged" concretely mean when facing a problem that drags on?
In the text, discouragement is the felt experience that pushes you to give up. Not being discouraged doesn't mean denying the difficulty. It means refusing to let the giant take up all the space in your mouth, your gaze, and your schedule. Concretely: keep praying, keep confessing the Word, keep taking the ordinary steps of obedience, even when nothing changes on the outside.
Why does David call Goliath "uncircumcised" instead of "giant"?
Where others see size, David sees the covenant, or rather its absence. An uncircumcised man, in the Old Testament, is someone who has no covenant with the living God. That shift in vocabulary resizes the problem. For you today, the equivalent is the blood of Jesus: whoever opposes you without a covenant with Christ does not get the last word over your life.
Does "taking courage" mean manufacturing your own courage alone, without God?
No. God doesn't abandon you in the fight, but he waits for a decision from you. To Joshua, he promises his presence and then commands: "Be strong and courageous." To Gideon, he reminds him of the strength already present in him. Courage is an act of faith that takes hold of what God has already given. It isn't self-persuasion, it's a step taken in response to his promise.
