The Prophet applies again to the present state of the people what he had before recorded—that God went forth with his Christ for the salvation of his people. Some consider that there is understood a particle of comparison, and repeat the verb twice, “As thou didst then go forth for the deliverance of thy people, so now wilt thou go forth for the deliverance of thy people with thy Christ.” But this repetition is strained. I therefore take the words of the Prophet simply as they are—that God went forth for the deliverance of his people. But when God’s people are spoken of, their gratuitous adoption must ever be remembered. How was it that the children of Abraham became the peculiar people of God? Did this proceed from any worthiness? Did it come to them naturally? None of these things can be alleged. Though then they differed in nothing from other nations, yet God was pleased to choose them to be a people to himself. By the title, the people of God, is therefore intimated their adoption. Now this adoption was not temporary or momentary, but was to continue to the end. Hence it was easy for the faithful to draw this conclusion—that they were to hope from God the same help as what he had formerly granted to the fathers.
