Charles H. Spurgeon on Psalms 145:17

The LORD is righteous in all his ways, etc. The ground upon which praise is here ascribed to God may seem a common one, being in every one's mouth; but in nothing is wisdom shown more than in holding fast the truth, that God is just in all his ways, so as to retain in our hearts an unabated sense of it amidst all troubles and confusions. Though all acknowledge God to be just, most men are no sooner overtaken by affliction than they quarrel with his severity: unless their wishes are immediately complied with, they are impatient, and nothing is more common than to hear his justice impeached. As it is everywhere abused by the wicked imputations men cast upon it, here it is very properly vindicated from such ungrateful treatment, and asserted to be constant and unfailing, however loudly the world may disparage it. It is expressly added, "in all his ways and works"; for we fail to give God due honour unless we recognise a constant tenor of righteousness in the whole progress of his operation. Nothing is more difficult in the time of trouble, when God has apparently forsaken us, or afflicts us without cause, than to restrain our corrupt feelings from breaking out against his judgments; as we are told of the Emperor Mauricius in a memorable passage of history, that seeing his sons murdered by the wicked and perfidious traitor Phocas, and being about to be carried out himself to death, he cried out —"Thou art righteous, O God, and just are thy judgments." —John Calvin.
