Isaiah 31:6 - Calvin's Commentary on the Bible

6. Return. This verse is explained in various ways; for the Hebrew commentators explain it thus, “Return to the Lord, for you have multiplied revolts.” But, in my opinion, the meaning is more simple: “Return according as you have made a deep revolt; (318) for לאשר ( lăăshĕr) is, I think, employed in the same sense as כאשר ( kăăshĕr), “according as.” (319) He means that the aggravated nature of their wickedness does not shut the door against them from returning to God, if they repent; that, although they have been sunk into the deepest wickedness, still God will pardon them. Yet, at the same time, he makes use of this spur to stimulate them to earnest grief and hatred of their sins, that they may not carelessly and lightly, as frequently happens, aim at a half repentance. He therefore bids them consider attentively with what fearful destruction they have cast themselves down to hell, that they may abhor themselves on account of their aggravated transgressions.

It ought first to be observed, that the Prophet does not lessen the guilt of the people. They who need to be brought back to the Lord must first be made to have a deep and painful conviction of their guilt; for they who flatter themselves in their iniquities are very far from obtaining pardon, and therefore there is nothing better than to lay open the alarming nature of the disease, when a remedy must be applied. Yet, that their hearts may not be led to despair, they must be encouraged and comforted by holding out to them the mercy of God; for Satan aims at nothing else than to cut us off from all hope of pardon. Accordingly, Isaiah declares that, although by their wickedness they have sunk down to hell, God is ready to forgive; for not in vain does the Lord invite us to repentance, but he likewise offers pardon. Hence also, to such exhortations the Scripture always adds promises of grace, that, whenever we are called to repentance, we may know that the hope of pardon is also held out to us.
