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 - 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.
“Blessed is the nation whose God is the Lord;
And the people whom He hath chosen for His own
The Lord looketh from heaven;
He beholdeth all the sons of men.
From the place of His habitation
He looketh upon all the inhabitants of the earth.” PK 50.1
“The Lord hath prepared His throne in the heavens;
And His kingdom ruleth over all.” PK 50.2
“Thy way, O God, is in the sanctuary:
Who is so great a God as our God?
Thou art the God that doest wonders:
Thou hast declared Thy strength among the people.” PK 50.3
