The Prophet confirms what he has been teaching, and encourages the faithful to rejoice, as though he saw with his eyes what he had previously promised. For thus the Prophets, while encouraging the faithful to entertain hope, stimulate them to testify their gratitude, as though God’s favor was already enjoyed. It is certain, that this instruction was set before the Jews for this purpose,—that in their exile and extreme distress they might yet prepare themselves to give thanks to God, as though they were already, as they say, in possession of what they had prayed for. But we must remember the design of our Prophet, and the common mode of proceeding which all the Prophets followed; for the faithful are exhorted to praise God the same as if they had already enjoyed his blessings, which yet were remote, and seemed concealed from their view.
