Not Rocket Science

In 1999 NASA lost the Mars Climate Orbiter because two teams were using different units of measurement. It turns out we make the same mistake with God. A reflection on Joel 3:1–5.

Joel 3:1–5 (Joel 2:28–32 in some editions)

Phrases that spoke to me today:
• And it shall come to pass afterward
• I will pour out my Spirit on all flesh
• your sons and your daughters shall prophesy
• your old men shall dream dreams, and your young men shall see visions
• everyone who calls on the name of the Lord shall be saved

Applying the Word to My Life:
When I was growing up I remember when NASA lost the Mars Climate Orbiter (back in 1999). The spacecraft had been traveling for nine months toward Mars — on time, on course, on budget — when it entered the Martian atmosphere at the wrong angle and broke apart. The investigation found the cause: Lockheed Martin had been transmitting thruster data in imperial units — pound-force seconds — while NASA's navigation software was expecting metric — newton-seconds. The math was right. The engineering was right. The spacecraft had done exactly what it was told. The only problem was a failure of translation between two measurement systems.

It isn't rocket science, but there are times in my life where I do something similar with God.

Joel writes his prophecy — that God will pour out His Spirit on all flesh, that sons and daughters will prophesy, that old men will dream and young men will see visions — and eight centuries pass. By human measurement, that is an eternity. Long enough to wonder if the promise was ever real, whether something had gone wrong somewhere along the way. But by God's measurement, it arrived exactly on schedule.

The tension I sometimes feel with God's promises is often this: I am running in human units and He is delivering in His. A day, a year, a decade feel enormous to us. The psalmist noted that a thousand years in God's sight pass like a single night watch. We hear that, nod, and then go back to measuring in hours. The mismatch isn't malice. It isn't forgetfulness. It is a difference in units.

This is part of what the spiritual home we have been building all week is for. The stability, the stillness, the peace paid in advance — none of that is just comfort. It is also calibration. The place where God meets us most clearly is also the place where we can borrow, for a moment, something closer to His frame of reference. We can't fully inhabit it — we are too small and too limited for that. But we can stand close enough to trust His timeline even when our own tells us the promise is overdue.

Joel's prophecy also helps us see the shape of this promise. In the Old Testament, the Spirit came on specific people for specific purposes — kings were anointed, prophets were filled, judges were empowered for a season. The Spirit was selective. If you weren't a king or a prophet, you encountered God's presence mostly through intermediaries. Joel says the day is coming when that structure dissolves entirely: all flesh. Sons and daughters. Old men and young men. Even servants. Every barrier the old system maintained — gender, age, social standing — falls at once. The presence that had to be mediated, that could only be approached through the right person in the right place, is about to be poured out directly on everyone who calls on the name of the Lord.

This is the prophecy that makes the whole week make sense. The disciples waiting in the upper room aren't waiting for a new king to be anointed or a new prophet to arise. They are waiting for the floodgates to open.

That is what Peter reaches for on Pentecost morning when he stands up before a bewildered crowd and tries to explain what they are witnessing. Not a new idea. Not an improvised explanation. He reaches back eight centuries and says: this is what that was about. The promise is being kept right now, in front of you.

We have spent this week learning to stay in the room, to be still, to seek His face, to receive the peace He paid in advance. Tomorrow we will read the story of when the fire came. But before He comes, we hold the prophecy — eight centuries old, delivered exactly on time — and trust the One who made it.

God's promise is always on time. We just keep using the wrong units.

My Response for Today:
Today I will hold one of God's promises that feels overdue — and measure it in His units instead of mine.
