Old Methods Can’t Win New Wars
Building a flywheel of success for life and career
Then Saul dressed David in his own tunic. He put a coat of armor on him and a bronze helmet on his head… ’I cannot go in these,’ he said to Saul, ‘because I am not used to them.’ So he took them off. — 1 Samuel 17:38–39
We all know the story of David and Goliath. But the quiet turning point happened just before the battle. Saul offered David a soldier’s armor—something heavy, clunky, and supposedly protective. But David tried walking in it and couldn’t. It wasn’t him. So he took it off.
David went instead with what he knew—a sling and a stone—and stepped into battle not with borrowed strength, but with personal conviction, trained skill, and clarity of mission.
I’ve worked across government, corporate, and startup environments. Saul’s armor reminds me of large-company processes—policies, layers of approvals, a dependence on what once worked. But this was a new kind of battle, and Saul’s armor—his tried-and-tested method—was useless. If it still worked, Saul and his army would've killed Goliath!
Startups and small teams especially face this. Leaders often bring corporate habits that made sense in bigger systems—but they stifle movement in early-stage settings. You can’t win today’s battles with yesterday’s methods. You need your own sling, honed by earlier battles, and the courage to walk forward without convention holding you back.
You can’t rely on yesterday’s methods when the battlefield has changed—especially during moments like Covid or crisis, when the old playbook no longer applies. David wasn’t reckless—he was trained, he was clear, and he was willing. That combination is what brings breakthrough.
Victory doesn't come from imitation--it comes from what God has placed in your heart and hand.
Action Items:
- Reflect on the “armor” you’re currently wearing—habits, titles, processes. Journal what feels foreign or outdated for your current battle.
- Identify your personal “sling”—skills or experiences God has uniquely trained you with. Where can you deploy them more courageously?
- If you lead others, create space for team members to shed misfitting roles or processes and embrace more authentic, effective ways of contributing.
