|Matthew Henry's Concise Commentary|
92:7-15 God sometimes grants prosperity to wicked men in displeasure; yet they flourish but for a moment. Let us seek for ourselves the salvation and grace of the gospel, that being daily anointed by the Holy Spirit, we may behold and share the Redeemer's glory. It is from his grace, by his word and Spirit, that believers receive all the virtue that keeps them alive, and makes them fruitful. Other trees, when old, leave off bearing, but in God's trees the strength of grace does not fail with the strength of nature. The last days of the saints are sometimes their best days, and their last work their best work: perseverance is sure evidence of sincerity. And may every sabbath, while it shows forth the Divine faithfulness, find our souls resting more and more upon the Lord our righteousness.
Verse 15. - To show that the Lord is upright. The happy and flourishing old age of the righteous (ver. 14; comp. Psalm 91:16) is a strong indication of God's faithfulness and truth, showing, as its does, that he keeps his promises, and never forsakes those that put their trust in him (comp. Psalm 27:10; Psalm 37:25; Isaiah 41:17, etc.). He is my Rock - rather, that he is my Rock - and that there is no unrighteousness in him. Both clauses depend on the "show" of the preceding hemistich.
Gill's Exposition of the Entire Bible
To show that the Lord is upright,.... Or righteous, that is, faithful; as he is in his counsels, covenant, and promises, which he makes good by causing his people to grow and flourish, and become fruitful; by carrying on the work of grace upon their souls, and by preserving them to the end safe to his kingdom and glory; by all which it appears that he does not and will not suffer his faithfulness to fail: the Targum is,
"that the inhabitants of the earth may show, &c.''
he is my Rock; the psalmist sets his seal to the truth of God's faithfulness, firmness, and constancy, calling him a Rock for his strength and stability, and claiming his interest in him; declaring he found him to be so by experience,
even the Rock whose work is perfect; who always completes what he undertakes, and finishes what he begins, and will not forsake the work of his own hands:
just and right is he; the Rock of ages, that remains firm, steadfast, and unalterable in all generations:
and there is no unrighteousness in him; as not in his sovereign acts of grace, so neither in his providential dispensations, either towards good men or bad men; not in suffering the wicked to prosper, as in Psalm 92:7, and the righteous to be afflicted; nor in punishing bad men here, or hereafter; nor in justifying sinners by the righteousness of his Son, and giving them the crown of righteousness at the last day: all his proceedings are in the most just and equitable manner; see Romans 9:14.
