John Gill Commentary Psalms 92:15

"To show that Jehovah is upright; He is my rock, and there is no unrighteousness in him." — Psalms 92:15 (ASV)

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''

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 (Psalms 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) .
