The Walls That Learned to Lean

When medieval builders raised the great Gothic cathedrals, they faced a problem. They wanted walls of light — towering windows of stained glass that would flood the sanctuary with color. But stone walls tall enough to hold those windows would collapse under their own weight.

The solution was the flying buttress — stone arms that reached from the outside to brace the walls. At Chartres Cathedral, built in the early thirteenth century, these arched supports allowed the builders to replace solid stone with some of the most magnificent stained glass windows in the world.

Here is what strikes me: the walls hold up not by being thick and self-sufficient but by leaning into support they cannot see from inside. Stand in the nave of Chartres and look up — you see only light pouring through glass. The buttresses that make it all possible are hidden outside, doing their work in silence.

Trust works the same way. We want to be self-sufficient walls — strong enough on our own, needing nothing. But God designed us to lean. The Psalmist wrote, "The Lord was my support" (Psalm 18:18). The strength that holds us up is often invisible from where we stand. We feel only the light streaming in.

The next time life asks you to stand taller than your own strength allows, remember Chartres. The walls that let in the most light are the ones that learned to lean.
