We have here God's answer to Jeremiah's prayer, designed to quiet his mind and make him easy; and it is a full discovery of the purposes of God's wrath against the present generation and the purposes of his grace concerning the future generations. Jeremiah knew not how to sing both of mercy and judgment, but God here teaches to sing unto him of both. When we know not how to reconcile one word of God with another we may yet be sure that both are true, both are pure, both shall be made good, and not one iota or tittle of either shall fall to the ground. When Jeremiah was ordered to buy the field in Anathoth he was willing to hope that God was about to revoke the sentence of his wrath and to order the Chaldeans to raise the siege. "No," says God, "the execution of the sentence shall go on; Jerusalem shall be laid in ruins." Note, Assurances of future mercy must not be interpreted as securities from present troubles. But, lest Jeremiah should think that his being ordered to buy this field intimated that all the mercy God had in store for his people, after their return, was only that they should have the possession of their own land again, he further informs him that that was but a type and figure of those spiritual blessings which should then be abundantly bestowed upon them, unspeakably more valuable than fields and vineyards; so that in this word of the Lord, which came to Jeremiah, we have first as dreadful threatenings and then as precious promises as perhaps any we have in the Old Testament; life and death, good and evil, are here set before us; let us consider and choose wisely.
