Lessons from the past to the future.
Those addressed are the people "named from Israel and sprung from Judah's spring;" who swear by Jehovah's Name and render homage to Israel's God—not, alas! so sincerely as they should. Still, they have learned to find their true reliance in Zion and in Jahveh. Let them, then, hear the exhortation of Jehovah.
I. THE ORACLE OF THE PAST. Jehovah has in former times predicted events by the mouth of his prophets which came to pass. Those predictions were disbelieved; the fulfilment was delayed; and yet suddenly the ideal was translated into fact; and the unexpected had come to pass. In general, history is the oracle of the Eternal. An empire founded on force or fraud cannot stand; the kingdom which subsists by righteousness and for righteousness carries with it vitality and enduring dominion. It was said by a great statesman, "The unexpected always happens." And in truth the purposes of God are not seldom known by their fulfilment in sudden and surprising events. He thinks long, but acts promptly. As in Northern climates, the winter of human discontent breaks as if by magic into spring. Such experiences should tend to subdue the obstinacy of incredulity. God knew that the Israelites were prone to unbelief and hardness of heart, and therefore had plied them with so many proofs of his providence. George Herbert mentions, "Bibles laid open, millions of surprises," among the means which God employs to bring the soul to himself. The "iron sinew and the brow of brass" are significant of the state of mind which he had to encounter in the people. "Some are so obstinately bad and confirmed in their vice, that judgments and afflictions are but thrown away upon them; and God's shooting at them is but shooting at a mark, which indeed receives the arrow, but does not at all feel it."
II. NEW PREDICTIONS. Again, things hidden from human penetration shall be made known by the Divine oracles. The events could no more be anticipated than could an act of creation from the operation of natural causes. And so the taking of Babylon by Cyrus, and the deliverance of the exiles from bondage, could be known by no human foresight or sagacity. But "their ears were not open." They were infidel and rebellious at heart. The open ear means the affected heart, the awakened understanding, the cherishing memory, the steady, fruitful perseverance in action. If there be defect of these, the soul is no better than if it had not heard at all. Nay, it may be worse (cf. John 5:25; John 6:45; Acts 2:37).
III. THE GREAT DIVINE MOTIVE. Not because the people have deserved it will Jehovah act thus, but for his honour's sake, because he is not yet known among the Gentiles. And it is through Israel that his purposes to the heathen must be carried out. Yet this people had not been found pure metal after their trial in the furnace of affliction. They were wicked, sinful, and unbelieving. It is his glory, then, in the spread of true religion and justice in the earth, that is the principle and the end of the procedure of Jehovah. As he can swear by no higher, so he can work for no more majestic object, than himself. But he must have instruments, he must have men, however imperfect, to work out his purposes. "God's glory is the motto inscribed upon every created being; and wheresoever God reads, he owns this superscription. It is all the creature has, under God's hand and seal, to show for its life. Wherever we are, we are not our own, but his. All men are by nature servants to the interest of his glory."—J.
