“To wait upon God is not to sit with folded hands and do nothing, but to wait as men who wait for the harvest. The farmer does not wait idly but with intense activity; he keeps industriously ‘at it’ until the harvest. To wait upon God is the perfection of activity. We are told to ‘rest in the Lord,’ not to rust” (Oswald Chambers, The Place of Help).
I think that says it all.
May all of us learn daily how to wait well as we rest (but not rust) in the Lord.
