Proverbs 3:5-6

Three commands and a promise, and the hinge of the whole thing is a contrast the proverb sets up and then refuses to soften. Trust in the LORD with all your heart — and the very next line names the rival: do not lean on your own understanding. Not discard your understanding; the book of Proverbs is itself an education, thirty-one chapters of hard-won sense. Lean. The word is about where we put our weight when the ground gives way. We are allowed to think. We are only warned against resting our whole selves on the thinking.

And that is harder than it sounds, because our understanding is the one counselor always in the room. It speaks in our own voice, with our own memories, sounding exactly like wisdom — which is why we rarely catch the moment we have shifted our weight onto it. The proverb is not asking us to be foolish. It is asking us to notice how quickly the thing we trust shrinks to the small sealed world we can see, and how reluctant we are to acknowledge him on the one road where we already feel sure of the map.

Then the promise: he will make straight your paths. Not flat — not easy — straight: pointed somewhere, going somewhere, even when every turn looks crooked from inside it.

We can only lean this way because Someone leaned first. Christ trusted the Father down a path that ran through a garden and a cross, a road that looked, from inside it, like the crookedest in history. He did not lean on his own understanding — not my will, but yours — and the paths were made straight all the way to an empty tomb. Our trust is only an echo of his.

Chambers is describing the very posture the proverb commands — a faith that has given up needing to see the road in order to keep walking it. We do not lean on our own understanding because we have found something better to lean on: not a map we have memorized, but the One holding the far end of the road, whom we know and love even when the next step is dark.
