God is in the details.
The real power here lies in reversing our usual thinking: we don't find meaning by standing back and viewing the grand scheme, but by getting close enough to see the joins, the seams, the careful choices that hold things together. Mies understood that indifference to small things—a poorly fitted door, a thoughtless material choice, a corner cut—signals indifference to the whole work. When you're renovating a kitchen and tempted to use cheaper hinges because "no one will notice," you're wrestling with exactly what Mies meant: that integrity compounds in the particulars, or dissolves there. The grace in anything well-made lives in decisions most people never consciously register, yet somehow feel.
