IV. They are taught to trust God further than they can see him. The prophet puts this word into their mouths, and goes before them in saying it (v. 15): Verily, thou art a God that hidest thyself. 1. God hid himself when he brought them into the trouble, hid himself and was wroth, ch. lvii. 17. Note, Though God be his people's God and Saviour, yet sometimes, when they provoke him, he hides himself from them in displeasure, suspends his favours, and lays them under his frowns: but let them wait upon the Lord that hides his face, ch. viii. 17. 2. He hid himself when he was bringing them out of the trouble. Note, When God is acting as Israel's God and Saviour commonly his way is in the sea, Ps. lxxvii. 19. The salvation of the church is carried on in a mysterious way, by the Spirit of the Lord of hosts working on men's spirits (Zech. iv. 6), by weak and unlikely instruments, small and accidental occurrences, and not wrought till the last extremity; but this is our comfort, though God hide himself, we are sure he is the God of Israel, the Saviour. See Job xxxv. 14.
