[To wait on God] means to pause and soberly consider our own inadequacy and the Lord’s all-sufficiency, and to seek counsel and help from the Lord, and to hope in Him (Psm. 33:20-22; Isa. 8:17)… The folly of not waiting for God is that we forfeit the blessing of having God work for us. The evil of not waiting on God is that we oppose God’s will to exalt Himself in mercy. God aims to exalt Himself by working for those who wait for Him.
