After God's Own Heart | Week 3: His Courage

Devotional

Day 1: The Underdog Story We Forget

The story of David and Goliath isn’t just about a boy with a sling. It’s about a God who rewrites the rules of every battle. When armies freeze in fear, God works through unlikely heroes who see beyond human limitations. Giants taunt, but faith remembers who holds the fight. The real underdog story isn’t David’s courage—it’s God’s power turning impossible odds into eternal victories. [11:48]

“Goliath stood and shouted to the ranks of Israel, ‘Why do you come out and line up for battle? Am I not a Philistine, and are you not the servants of Saul? Choose a man and have him come down to me. If he is able to fight and kill me, we will become your subjects; but if I overcome him and kill him, you will become our subjects and serve us.’… On hearing the Philistine’s words, Saul and all the Israelites were dismayed and terrified.”
(1 Samuel 17:8–11, NIV)

Reflection: What “giant” in your life feels like a daily taunt? How might your perspective shift if you saw it as God’s battle rather than yours?

Day 2: When Courage is Capped by Comparison

Fear paralyzes when we measure ourselves against the problem. The Israelite army did the math: Goliath’s height, armor, and reputation outweighed their strength. But faith isn’t arithmetic. David refused to compare his sling to a spear. He traded calculations for confidence in the God who had already delivered him from lions. Courage grows when we stop sizing up giants and start sizing up God. [19:15]

“David said to Saul, ‘Your servant has been keeping his father’s sheep. When a lion or a bear came and carried off a sheep from the flock, I went after it, struck it, and rescued the sheep from its mouth… The Lord who rescued me from the paw of the lion and the paw of the bear will rescue me from the hand of this Philistine.’”
(1 Samuel 17:34–37, NIV)

Reflection: Where have you let comparison with your “giant” shrink your courage? What past deliverance can you recall to fuel faith today?

Day 3: The Shepherd’s Resume vs. the King’s Armor

Saul tried to dress David in royal armor, but it clanked and clattered. God’s battles aren’t won with borrowed strength. David stripped down to a sling, staff, and five stones—tools of his everyday faithfulness. Victory came not through pretending to be someone else, but through trusting the God who’d shaped him in hidden fields. Our most powerful weapon is the identity God forged in obscurity. [24:23]

“Then [David] took his staff in his hand, chose five smooth stones from the stream, put them in the pouch of his shepherd’s bag and, with his sling in his hand, approached the Philistine.”
(1 Samuel 17:40, NIV)

Reflection: What “armor” have you worn to appear stronger? How might God want to use your authentic, unpretentious gifts instead?

Day 4: The Battle Belongs to the Lord

David didn’t declare war on Goliath—he announced a verdict. “The battle is the Lord’s” wasn’t a pep talk but a proclamation. While others saw a shepherd boy, David saw a God who needed no backup. The speech before the stone flew was the real victory. Faith speaks truth to giants before the first punch is thrown. [28:58]

“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… 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.’”
(1 Samuel 17:45–47, NIV)

Reflection: What problem have you claimed as “yours to fix”? How would it change your posture to declare, “This battle is God’s”?

Day 5: The Champion Who Already Won

David’s story points beyond stones and giants. Centuries later, another descendant of Bethlehem faced a greater foe. Jesus walked unarmed into death’s valley, disarming evil through a cross. His resurrection proved no giant—not cancer, grief, or even death—gets the final word. Our champion doesn’t just fight for us; He’s already written the victory. [42:56]

“And having disarmed the powers and authorities, [Jesus] made a public spectacle of them, triumphing over them by the cross.”
(Colossians 2:15, NIV)

Reflection: Where do you need to stop striving and start resting in Jesus’ finished victory? How can His triumph over death reshape your view of today’s battles?

Sermon Summary

The valley in 1 Samuel 17 sets two ridges, two armies, and one taunting giant across a dry creek bed. Goliath stands nine feet tall, armored in bronze, and dares Israel to send a champion. The army hears the dare every morning and freezes, because the math looks brutal: he is division one, they feel JV. The crowd becomes “the frozen,” while Goliath becomes “the flexing,” and both postures are wrong. Fear stares at the problem and shrinks. Pride stares at the self and swells.

David steps in with a different posture. The teenager who was only delivering bread and cheese hears Goliath defying the armies of the living God, and something rises that is not bluster. David doesn’t argue; he remembers. “A lion and a bear” already met the Lord’s deliverance, so the same God will do it again. Saul tries to make David look bigger with oversized armor, but the shepherd shrinks his gear instead of inflating his ego. The sling, the stones, the staff, and a Name are enough, because the key line is not tactical, it is theological: “You come with sword and spear, but I come in the name of the Lord of armies… the battle is the Lord’s.” That sentence wins the fight before the stone flies.

The battle itself is one verse long. The speech is longer because faith’s confession is the real turning point. The text refuses to let this be only an underdog tale. On paper it is David vs. Goliath; in reality it is God vs. Goliath, and those odds never wobble. The giant is not the variable. The only variable is the size of God in human eyes.

A living parable walks onstage when David Collins tells of his son Declan. “Your child has cancer” lands like a giant in the room. Surgery removes one tumor; blindness follows; chemo stretches out fifty-one weeks. Prayer gathers every Sunday. Then sight returns, and the only word that fits is “Jesus.” The church is not handed a formula; it is handed a reminder. Some stories end with visible miracles, some with waiting and tears, but all are enfolded by a Champion who already won. The line of David gives a better David. Jesus steps into the valley stripped of armor, carries a cross, and breaks the last Goliath, death itself. The call is simple and costly: name the giant, and then write whose fight it is. The battle belongs to the Lord.

Key Takeaways

1. The battle really belongs to God. The text refuses to center human muscle or technique. David answers a sword with a Name and declares the decisive truth before he ever takes a step. When ownership shifts from self to God, courage stops being manufactured and starts being received. [28:58]
2. Courage grows by remembering deliverance. David’s boldness is not hype; it is memory. Yesterday’s bear and lion become today’s receipts of grace, and memory turns panic into trust. Spiritual amnesia breeds fear; remembrance breeds a steady, quiet yes. [25:19]
3. Smallness becomes strategic surrender. Saul’s armor tries to solve fear by optics, but faith shrinks the gear and enlarges God. The sling looks foolish, yet it signals a refusal to play by Goliath’s rules. Surrender is not passivity; it is alignment with how God actually saves. [27:08]
4. Stop comparing; enlarge God’s size. The valley exposes a bad metric: courage capped by comparison. The giant was never the variable; the only variable was how big God was in their eyes. Worship resets the scale, so fear loses its leverage. [32:48]
5. Jesus stands as the greater Champion. David points forward to a Son of David who defeats a darker enemy with no armor and a cross. If death has been defanged, every lesser giant has already been put on notice. Hope rests not on outcomes controlled but on a victory secured. [42:56]

Bible Study Guide

Bible Reading
1 Samuel 17:45-47 (ESV)
“Then David said to the Philistine, ‘You come to me with a sword and with a spear and with a javelin, but I come to you in the name of the Lord of hosts, the God of the armies of Israel, whom you have defied. This day the Lord will deliver you into my hand, and I will strike you down and cut off your head. And I will give the dead bodies of the host of the Philistines this day to the birds of the air and to the wild beasts of the earth, that all the earth may know that there is a God in Israel, and that all this assembly may know that the Lord saves not with sword and spear. For the battle is the Lord’s, and he will give you into our hand.’”

Observation questions

What three weapons does Goliath use, and what does David contrast them with in his response?
According to David’s speech, what is the ultimate purpose of the battle’s outcome?
The sermon mentions that the actual battle scene in 1 Samuel 17 is “one verse long.” Why might the text focus more on David’s words than the physical fight? [30:26]
How does David describe God’s role in the battle in verse 47?

Interpretation questions

Why do you think David’s refusal to use Saul’s armor (choosing a sling and stones instead) was significant to the story’s message?
The sermon says, “The giant was never the variable; the variable was the size of God in their eyes.” What does this mean about how fear or faith operates in our lives? [32:48]
David’s confidence came from remembering God’s past deliverance (lion and bear). How does recalling past faithfulness shape our ability to face current challenges?
How does Jesus’ victory over death, as the “greater Champion,” change the way we view our own “giants”? [42:56]

Application questions

What “giant” in your life feels like it’s “taunting you every morning” (e.g., fear, doubt, a relational struggle)? How might naming it as God’s battle shift your perspective? [19:38]
David remembered God’s faithfulness with the lion and bear. What past experience of God’s deliverance in your life can you hold onto when facing current challenges?
Saul tried to make David “look bigger” with armor. Are there areas where you’re tempted to rely on your own “armor” (e.g., status, control, appearances) instead of surrendering to God’s way? What would “smallness” look like in that situation? [27:08]
The sermon shares Declan’s story of healing but acknowledges that some miracles come through “waiting and tears.” How can you trust God’s faithfulness even when outcomes don’t match your hopes? [41:11]
How might worshiping God for His character (not just His solutions) help you “enlarge God’s size” in your eyes this week?
The battle belongs to the Lord, but we’re called to step into the valley (like David). What practical step can you take this week to act in faith, even if it feels small?
Jesus defeated death, the “last Goliath.” How does His victory give you hope in the face of seemingly impossible circumstances?

#CourageFromFaith

“And so now notice what David's not doing here. He's not he's not puffing himself up. He's not bragging about how strong he is. He's looking at his past and God's faithfulness in the past. The lion and the bear. He's like, God showed up when I fought a lion. And when I fought a bear, he's gonna show up again. And so what is David doing? He's just doing a completely different kind of math, looking at the same giant that everyone else is. I don't think that David was any braver than any other soldier in this army. He just remembered what the rest of the army forgot. He remembered that God was in this fight. And so it wasn't like David woke up this morning, the morning that he did this, and he's like, I'm gonna just muster up enough courage. No. It was courage that he had because he remembered God's faithfulness and he had seen it. And because of that, he could step into this moment.”

#TheBattleIsTheLords

“And and he says that the battle is the Lord's. None of the other soldiers seem to remember this. They were looking at themselves in comparison to Goliath, and they're like, if it's my battle, I've got no shot. David's like, it's not my battle. The battle is the Lord's. And because of that, because David knew it wasn't his battle in the first place, he found the courage to actually walk forward to step into battle with Goliath in this moment when everyone else was going the other direction.”

52s

#SmallButMighty

“And everyone else's idea and if every soldier there would have been like, I'm gonna try to be as big as Goliath is. I'm gonna try to match his size. I'm gonna try to come with a sword. And David's idea, David's concept is I'm gonna just stop measuring myself against Goliath. And so all of a sudden, David shows up and he walks forward into the battleground, into the showdown with Goliath. And Goliath just is like, oh, that's okay. And he's in his first response, Goliath looks down at David and basically just starts laughing. He's like, wow. This is the best you guys have is this little kid. Wow. What shot do you guys have? This is his response. Am I a dog that you come at me with sticks? By every measure that Goliath could see, David just showed up to a sword fight with a pocket full of rocks.”

#GodIsTheDifference

“Every soldier in that army looked at the same giant. And the only difference from David's point perspective is that he understood that God was bigger. That was the one variable. The the giant was never the variable. The variable was the size of God in their eyes. And for David, God was so much bigger than this problem, than this challenge that he was looking at.”

#SeeTheFullStory

“Now I'm gonna guess that we've all heard this story before. And most of the time when we hear it, we kind of assume that the message underneath the surface is if you wanna be more like David, you just need to muster up a little bit more courage. And so often when we try to do that, it's not helpful. And sometimes we even feel defeated, but I wanna say something here today that I think is really underneath the surface of this text that might change the way that you view this text, It might change the way that you view the problems that are happening in your life, the giants that you face in your life. See, we read this story, and we always assume it's this, David versus Goliath, the underdog story.”

44s

#PutMeInCoach

“And suddenly, David does something that's kind of audacious. He goes to King Saul, and he's like, look. Here's the deal. If there's no one in this army that has enough courage to step up and fight Goliath, then put me in coach. I'll do it. And Saul's response is like, okay. Have you thought about this, buddy? Right? I'm not quite sure you've really given this a lot of thought. And, basically, Saul says, you're just a boy. And Saul's like, I've been a soldier my whole life. I've been trained. And if you think I can't fight this guy, then what shot do you have? And David does not response respond with an argument. He responds with his resume, basically, and he's like, hear me out. And he tells this story, and he says, I've already seen God's faithfulness.”

#UnderdogClassic

“And I think we do the same thing in our lives. I think we all have giants in our lives. We all have challenges in our lives. And sometimes it feels a little bit like we get up in the morning and the the giant, the challenge in our life is just taunting us whenever we wake up in the morning. And we just wake up every morning, and we just feel like whatever problem, whatever issue you have, and I don't know what it is for you this morning. It might be a relationship thing. It might be a financial thing. It might be a medical thing. We all have different things going on. It might be an addiction. And so what happens so often is our our problems when we look at our problems, feel nine foot tall.”

35s

“Now if there's one kind of story that we love, it's an underdog story. Who doesn't love the underdog? Right? We all are cheering for the underdog. I love that. You know? And we love it in all different kinds of areas of life. In sports, it's like if it's the 16 seed against the one seed in March Madness, I'm cheering for the 16 seed. Anyone else, you know, you just kinda wanna see the little guy take the big guy down. Or if it's in business, we're cheering for the startup going against the big behemoth company rate or in literature. I mean, who doesn't root for Frodo and Sam going against Mordor? What hope do they have? Right?”
