Psalms 77:9

9.Hath God forgotten to be merciful? The prophet still continues debating with himself the same subject. His object, however, is not to overthrow his faith, but rather to raise it up. He does not put this question, as if the point to which it refers were a doubtful matter. It is as if he had said, Hath God forgotten himself? or, hath he changed his nature? for he cannot be God unless he is merciful. I indeed admit that he did not remain unshaken as if he had had a heart of steel. But the more violently he was assailed, the more firmly did he lean upon the truth, That the goodness of God is so inseparably connected with his essence as to render it impossible for him not to be merciful. Whenever, therefore, doubts enter into our minds upon our being harassed with cares, and oppressed with sorrows, let us learn always to endeavor to arrive at a satisfactory answer to this question, Has God changed his nature so as to be no longer merciful? The last clause, Hath he shut up or restrained his compassions in his anger? is to the same effect. It was a very common and notable observation among the holy patriarchs, That God is long — suffering, slow to wrath, ready to forgive, and easy to be entreated. It was from them that Habakkuk derived the statement which he makes in his song,

“Even in his anger he will be mindful of his mercy.” (Habakkuk 3:2)

The prophet, then, here comes to the conclusion, that the chastisement which he felt would not prevent God from being again reconciled to him, and returning to his wonted manner of bestowing blessings upon him, since his anger towards his own people endures only for a moment. Yea, although God manifests the tokens of his anger, he does not cease most tenderly to love those whom he chastises. His wrath, it its true, rests continually upon the reprobate; but the prophet, accounting himself among the number of God’s children, and speaking of other genuine believers, justly argues from the impossibility of the thing, that the temporary displeasure of God cannot break off the course of his goodness and mercy.
