Trust in the Lord with all your heart and do not lean on your own understanding. In all your ways acknowledge him and he will direct your paths. (Proverbs 3:5–6) When the Bible tells us in this verse not to lean on our own understanding, it is not encouraging us to be irrational. The Bible puts up no wall of separation between our intellect and faith. In fact, the book of Proverbs speaks very highly of understanding:
"[Incline] your heart to understanding" (Proverbs 2:2).
"Raise your voice for understanding" (Proverbs 2:3).
"Understanding will guard you" (Proverbs 2:6).
"Blessed is the one who…gets understanding" (Proverbs 3:13).
"Wisdom rests in the heart of a man of understanding" (Proverbs 14:33).
"The heart of him who has understanding seeks knowledge" (Proverbs 15:14).
"To get understanding is to be chosen rather than silver" (Proverbs 16:16).
"Buy wisdom, instruction, and understanding" (Proverbs 23:23).
So if we're supposed to get understanding, why are we not supposed to lean on it?
