15 With your arm you have made your people free, the sons of Jacob and Joseph. (Selah.) 16 The waters saw you, O God; the waters saw you, they were in fear: even the deep was troubled. 17 The clouds sent out water; the skies gave out a sound; truly, your arrows went far and wide. 18 The voice of your thunder went rolling on; the world was flaming with the light of the storm; the earth was shaking. 19 Your way was in the sea, and your road in the great waters; there was no knowledge of your footsteps. 20 You were guiding your people like a flock, by the hand of Moses and Aaron.
Matthew Henry's Commentary on Psalm 77:15-20
Commentary on Psalm 77:11-20
(Read Psalm 77:11-20)
The remembrance of the works of God, will be a powerful remedy against distrust of his promise and goodness; for he is God, and changes not. God's way is in the sanctuary. We are sure that God is holy in all his works. God's ways are like the deep waters, which cannot be fathomed; like the way of a ship, which cannot be tracked. God brought Israel out of Egypt. This was typical of the great redemption to be wrought out in the fulness of time, both by price and power. If we have harboured doubtful thoughts, we should, without delay, turn our minds to meditate on that God, who spared not his own Son, but delivered him up for us all, that with him, he might freely give us all things.
