The Code That Kept Going

On July 20, 1969, as Apollo 11 descended toward the lunar surface, alarms started blaring in the cockpit. The onboard guidance computer flashed a 1202 error — it was being overwhelmed with more data than it could process. In that moment, everything NASA had worked toward hung in the balance.

But software engineer Margaret Hamilton had designed the system with what she called priority scheduling. When overloaded, the computer didn't freeze or shut down. It dropped low-priority tasks and kept running the ones that mattered most — the calculations that would land two human beings safely on the Moon.

Mission Control's call came through: "We're go on that alarm." Armstrong trusted the code and kept descending.

There are seasons in every believer's life when the alarms start sounding — when grief, uncertainty, and fear pile up faster than we can process them. The Psalmist knew those moments well: "When I am afraid, I put my trust in You" (Psalm 56:3). Courage doesn't mean the alarms stop ringing. It means knowing what to hold onto and what to release. We drop the anxiety. We drop the need to control every outcome. And we keep moving toward the purpose God has set before us.

Hamilton's software didn't need silence to function. It needed clarity about what mattered most. So do we. The courage God gives isn't the absence of overload — it's the grace to keep going through it.
