For though he cause grief, yet will he have compassion according to the multitude of his loving kindnesses.
But we must at the same time bear in mind what I have before shewed, that the faithful are exposed to various evils, because it is profitable for them to be chastised by God’s hand. Hence appears the necessity of this doctrine, for were we exempt frown all adversities, this admonition would be superfluous. But as it cannot be but that God will smite us with his rods, not only because we deserve to be smitten, but also because it is expedient, it is necessary to flee to this consolation which is offered to us, even that God having afflicted us with grief will again shew us compassion, even according to the multitude of his mercies He confirms the truth of what he alleges by a reference to the very nature of God himself. Hence, that the faithful might not debate with themselves whether God would be propitious to them, after having inflicted on them a temporary punishment, the Prophet comes to their aid, and sets before them the mercy of God, or rather mercies, in the plural number; as though he had said, that it could not be that God should deny himself, and that therefore he would be always merciful to his people; for otherwise his mercy would be obliterated, yea, that mercy which is inseparable from his eternal essence and divinity.
