What It Takes | 1 Samuel 17:1-54
As Labor Day approaches and we reflect on work, calling, and purpose, many of us find our thoughts drifting to our own struggles—whether at our jobs, in our families, or within ourselves. This very theme was addressed by Charlie Wallace in his sermon, “What It Takes,” centered around the iconic story of David and Goliath. Drawing inspiration from Charlie’s words and the lessons of Scripture, let’s dive deeper into what it truly means to be a person after God’s own heart—and why that journey continues to matter profoundly today.
The Shortage of Courageous, Godly Leaders
One of the first points Wallace addresses is the noticeable shortage of men—and women—who actively chase after God’s heart. Why is this the case? The answer, delivered with clarity and conviction, traces back to four key reasons: a lack of spiritual mentorship, misplaced worldly priorities, weak theological foundations, and shifting moral values.
Lack of Mentorship
Many people grow up without robust spiritual guidance, either at home or in their church communities. Without role models to illustrate authentic faith and perseverance, it’s easy to drift. Wallace puts it simply: “A country, a community, even, specifically, I would say this is only as strong as their men are strong…only as strong as their spiritual health of the men.” It’s a wake-up call for all of us to seek mentors—and, if we can, to be one for someone else.
Worldly Priorities and Weak Theology
Modern culture bombards us with instant gratification, materialism, and the myth that happiness comes quickly. Spiritual growth, by contrast, is a process that cannot be rushed. It “takes time,” Wallace reminds us. We also need sound, biblical teaching that roots us in truth—without it, our character cannot be shaped to reflect God Himself.
Shifting Values
Finally, as the world’s values subtly (or not so subtly) shift, we risk losing sight of what matters most. Faith, when lived according to the unchanging character of God, becomes counter-cultural.
Seeing Obstacles as Opportunities
While the shortage of godly leaders is concerning, Wallace is quick to remind us that every challenge is an opportunity in disguise—a chance for God to be glorified and for His power to be revealed through our weakness.
Take David: merely a shepherd boy, running errands between the sheep pastures and the battlefield, he was being unwittingly prepared for his greatest moment. Standing before a giant wasn’t just chance; it was the culmination of years of quiet obedience. In our own lives, those dull or difficult seasons may be God’s way of equipping us for future battles we can’t yet see.
“God is going to give us opportunities. Some might see them as threats. Some might see them as risks. And maybe they are. Maybe God’s opportunities are risky,” Wallace says. The key? To recognize God’s hand at work, even when the path is uncertain.
Preparation: The Unseen Work Before the Victory
David’s triumph over Goliath wasn’t spontaneous bravery—it was the result of a lifetime of preparation. While tending sheep, David faced down predators like lions and bears. He fought with courage when no one was watching, laying the groundwork for public victory.
We, too, are called to this rhythm. Spiritual discipline—prayer, Bible study, loving others, service—these are the “lions and bears” we face in obscurity. We might not wake up one morning completely transformed, but each day of faithfulness builds within us the character needed for bigger battles. As Wallace puts it, “Part of our sanctification process is God’s work…but part is also our work.”
Don’t underestimate the value of small, everyday moments of obedience. They are your training ground.
Courage: Action in the Face of Fear
The story of David and Goliath is ultimately about courage—not the absence of fear, but moving forward despite it. Every Israelite saw Goliath as an insurmountable threat; David saw him as an opportunity for God’s power to shine.
Courage may look like stepping into a leadership role, speaking truth when it’s unpopular, or simply being faithful in an ordinary task. True biblical courage is rooted not in our own self-confidence but in the conviction that God is for us and working through us. David was confident, yes, but his confidence was grounded in God’s previous faithfulness: “The Lord, who delivered me from the paw of the lion and from the paw of the bear, will deliver me from the hand of this Philistine.”
Do you find yourself shrinking from challenges? Ask God to make you brave, knowing He will give you the courage you need for every trial.
Key Attributes of a Person After God’s Heart
As Wallace concludes, he lays out three essential qualities for those who long to be after God’s own heart:
1. Complete Surrender
Becoming more like Christ is a process—and it begins with surrender. Which area of your life do you most need to place in God’s hands? Start there. Surrender is rarely easy, but it’s always worth it.
2. Obedience in the Face of Fear
Faithful obedience, even when you’re afraid, honors God. Will you keep trusting Him when the pressure is high or the stakes are great? Step out, even trembling, knowing that Godly courage is often cultivated one small “yes” at a time.
3. Cultivating a Humble Spirit
Courage and humility go hand in hand. Sometimes we wrongly call our reluctance “humility”—but, as Wallace notes, saying “I can’t do that” is often pride, not true humility, if we’re ignoring what God can do through us. Humility is acknowledging our limits but trusting God’s limitless power.
What Giants Are You Facing?
David never could have defeated Goliath without years of preparation, a keen sense of opportunity, diligent work, and God-given courage. Perhaps you find yourself wondering if you have what it takes. The truth is, none of us do—at least not on our own. But by following David’s example and trusting in a God who still does miracles, we can become people after God’s own heart.
Reflect:
What obstacles in your life might actually be disguised opportunities for God to work?
Which spiritual disciplines or habits do you need to “put in the work” on?
Where do you need courage—and are you willing to ask God for it, knowing He may answer with new challenges to stretch your faith?
Who in your life could use encouragement or mentorship—even as you seek it from others?
Take heart: the story of David reminds us that God isn’t looking for the most qualified, but for those willing to surrender, prepare, and step out in faith. Your next “Goliath” could be the stage for God’s greatest work through you.
If you’re ready to become a person after God’s own heart, start today—with surrender, obedience, humility, and courage. The journey will not be easy, but it will absolutely be worth it.
