Thou art the God that doest wonders - It is, it must be, the characteristic of God, the true God, to do wonderful things; things which are suited to produce amazement, and which we can little hope to be able to understand. Our judgment of God, therefore, should not be hasty and rash, but calm and deliberate.

Thou hast declared thy strength among the people - Thou hast manifested thy greatness in thy dealings with the people. The word "people" here refers not especially to the Hebrew people, but to the nations - the people of the world at large. On a wide scale, and among all nations, God had done that which was suited to excite wonder, and which people were little qualified as yet to comprehend. No one can judge aright of what another has done unless he can take in the whole subject, and see it as he does who performs the act - unless he understands all the causes, the motives, the results near and remote - unless he sees the necessity of the act - unless he sees what would have been the consequences if it had not been done, for in that which is unknown to us, and which lies beyond the range of our vision, there may be full and sufficient reasons for what has been done, and an explanation may be found there which would remove all the difficulty.

Thou - doest wonders - Every act of God, whether in nature or grace, in creation or providence, is wondrous; surpasses all power but his own; and can be comprehended only by his own wisdom. To the general observer, his strength is most apparent; to the investigator of nature, his wisdom; and to the genuine Christian, his mercy and love.

Thou art the God that doest wonders,.... In nature, providence, and grace; it seems chiefly to regard what was done for the Israelites in Egypt, and in the wilderness, see Psalm 78:12,

thou hast declared thy strength among the people; the nations of the world, who heard what the Lord did for Israel by his mighty power, and with an outstretched arm, as follows.

Thou art the God that doest wonders: thou hast declared thy strength among the people.

14-20. Illustrations of God's power in His special interventions for His people (Ex 14:1-31), and, in the more common, but sublime, control of nature (Ps 22:11-14; Hab 3:14) which may have attended those miraculous events (Ex 14:24).

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.
