2. Yet let them know that they must desire and expect it (v. 37): I will yet for this be enquired of by the house of Israel. God has spoken, and he will do it, and he will be sought unto for it. He requires that his people should seek unto him, and he will incline their hearts to do it, when he is coming towards them in ways of mercy. (1.) They must pray for it, for by prayer God is sought unto, and enquired after. What is the matter of God's promises must be the matter of our prayers. By asking for the mercy promised we must give glory to the donor, express a value for the gift, own our dependence, and put honour upon prayer which God has put honour upon. Christ himself must ask, and then God will give him the heathen for his inheritance, must pray the Father, and then he will send the Comforter; much more must we ask that we may receive. (2.) They must consult the oracles of God, and thus also God is sought unto and enquired after. The mercy must be, not an act of providence only, but a child of promise; and therefore the promise must be looked at, and prayer made for it with an eye of faith fastened upon the promise, which must be both the guide and the ground of our expectations. Both these ways we find God enquired of by Daniel, in the name of the house of Israel, when he was about to do those great things for them; he consulted the oracles of God, for he understood by books, the book of the prophet Jeremiah, both what was to be expected and when; and then he set his face to seek God by prayer, Dan. ix. 2, 3. Note, Our communion with God must be kept up by the word and prayer in all the operations of his providence concerning us and in both he must be enquired of.
