Trust in Yahweh with all your heart, and lean not on your own understanding; in all your ways acknowledge Him, and He will direct you on pleasant paths.Proverbs 3:5-6
The word for trust in this famous passage has shades of meaning which include confidence and boldness, running to a secure place for refuge, being free of care or worry, having a steadfast hope. All of these are different ways of representing the believer’s inner reliance on Yahweh.
It is not an admonishment that we are to abandon all reason and understanding. We are simply not to have our own wisdom as the primary source of our planning and our actions. We must leave room for direction from God, maintaining a view to his kingdom and purpose in this life.
The language used here can be likened to a traveler who is trekking through a wilderness in fog. He uses his wisdom and understanding to find the path that will take him where he needs to go. However, once he is on the path, he places his confidence in the path that it will carry him to his destination, even though because of the fog he cannot see the full length of where it is heading. He is carefree from having to choose his own potentially hazardous way through the wilderness,
Our wisdom instructs us to find the path; the path is that in which we place our trust, since it has been provided by God. We have confidence the path that God provided will lead us to our destination. God promises the path will be smooth and pleasant compared to the directionless wilderness ways of our own choosing.
Get on the path, stay on the path, follow the path.
