This then is what the prophet means when he adds—Art not thou our God? The question is much more emphatical than if he had simply declared that the true God was worshipped in Judea, and would therefore be the protector of that nation; for when the Prophet puts a question, he means, according to what is commonly understood in Hebrew, that the thing admits of no doubt. “What! art not thou our God?” We hence see that there is a contrast between the wicked and impious boastings in which the profane indulge, and the holy confidence which the faithful have, who exult in their God. But that the discourse is addressed to God rather than to the ungodly is not done without reason, for it would have been useless to contend with the wicked. This is indeed sometimes necessary, for when the reprobate openly reproach God we cannot restrain ourselves; nor is it right that we refrain from testifying that we regard all their slanders as of no account; but we cannot so courageously oppose their audacity as when we have the matter first settled between us and God, and be able to say with the Prophets—“Thou art our God.” Whosoever then would boldly contend with the ungodly must first have to do with God, and confirm and ratify as it were that compact which God has proposed to us, even that we are his people, and that he in his turn will be always our God. As then God thus covenants with us, our faith must be really made firm, and then let us go forth and contend against all the ungodly. This is the order which the Prophet observes here, and what is to be observed by us—Art not thou our God?
