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 Psa 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 Rom 9:14.
