“Trust in the LORD with all your heart, and don’t lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight.”
It does not say stop thinking. Proverbs spends thirty more chapters telling you to think harder.
What it means
“Lean” is a word for putting your weight on something — a stick, a wall. The question is not whether you use your understanding but what you rest on when your understanding runs out, which it will.
“Straight” translates a word closer to level or smooth than to short. The promise is a path you can actually walk, not a shortcut, and not a map handed over in advance.
What it does not mean
It does not promise the way will be easy, quick, or obvious. Plenty of straight paths run uphill.
It is not an instruction to abandon judgment, ignore advice, or treat impulses as guidance. “In all your ways acknowledge him” is closer to keeping God in view across the whole of an ordinary life than to waiting for a sign before each decision.
Where it sits
These lines sit in the opening section of Proverbs, framed as a father instructing a son. That frame matters: this is wisdom literature, describing how life generally goes, not a contract with clauses.
The book that contains it is relentlessly practical about planning, saving, listening to counsel and watching your words. Whatever verse 5 is warning against, it is not thoughtfulness.

God, I have thought about this as far as thinking goes. I am putting my weight on you rather than on my own read of it. Keep me honest about what I do not know, and make the path level enough to walk. Amen.
