What does Proverbs 3:5 really mean?

"Don't lean on your own understanding" means God wants you to ignore reason and just follow your gut feelings. This is probably the most common distortion of the verse, and it runs in two opposite directions. Some use it to dismiss careful thinking entirely — as if study, planning, and good reasoning were acts of faithlessness. Others hear it as an endorsement of strong impressions and emotional certainty over against careful thought. Neither reading fits the context. The verse does not say "ignore your mind" — it says don't lean on it as the load-bearing wall of your life. Verse 6 assumes you are actively walking through decisions: "in all thy ways acknowledge him." The correction is not from thinking to feeling but from self-sufficiency to dependence. Gill is careful here: human understanding is not condemned because thinking is bad, but because the understanding as fallen and unaided cannot reach the things of God on its own — it needs to be ordered by something outside itself. JFB frames it as a symmetry: full trust in God and full distrust of self-as-final-authority are two sides of the same coin. The person who reasons carefully while acknowledging God throughout is exactly what Proverbs is cultivating — not someone who has stopped using their mind, but someone who has stopped worshipping it.
