He will turn many of the children of Israel to the Lord, their God.
That the glory of conversion and faith, on the other hand, may remain undivided with God alone, Scripture frequently reminds us that ministers are nothing in themselves; but in such cases he compares them with God, that no one may wickedly steal the honor from God and convey it to them. In short, those whom God, by the aid of the minister, converts to himself, are said to be converted by the minister, because he is nothing more than the hand of God; and both are expressly asserted in this passage. Of the efficacy of the doctrine we have now said enough. That it lies not in the will and power of the minister to bring men back to God, we conclude from this that John did not indiscriminately bring all back, (which he would unquestionably have done, if every thing had yielded to his wish,) but only brought those back whom it pleased the Lord effectually to call. In a word, what is here taught by the angel is laid down by Paul in his Epistle to the Romans, that faith cometh by hearing, (Romans 10:17,) but that those only to whom the Lord inwardly reveals his arm (Isaiah 53:1; John 12:38) are so enlightened as to believe.
