(2.) That God will renew his covenant with the gospel-Israel, and will incorporate it a church to himself, by as full and ample a charter as that whereby the Old-Testament church was incorporated; nay, and its privileges shall be much greater: "In the place where it was said unto them, You are not my people, there shall you be again admitted into covenant, and owned as my people." The abandoned Gentiles in their respective places, and the rejected Jews in theirs, shall be favoured and blessed. There, where the fathers were cast off for their unbelief, the children, upon their believing, shall be taken in. This is a blessed resurrection, the making of those the people of God that were not a people. Nay, but the privilege is enlarged; now it is not only, You are my people, as formerly, but You are the sons of the living God, whether by birth you were Jews or Gentiles. Israel under the law was God's son, his first-born, but then they were as children under age; now, under the gospel, they have grown up both to greater understanding and greater liberty, Gal. iv. 1, 2. Note, [1.] It is the unspeakable privilege of all believers that they have the living God for their Father, the ever-living God, and may look upon themselves as his children by grace and adoption. [2.] The sonship of believers shall be owned and acknowledged; it shall be said to them, for their comfort and satisfaction, nay, and it shall be said for their honour in the hearing of the world, You are the sons of the living God. Let not the saints disquiet themselves; let not others despise them; for, sooner or later, there shall be a manifestation of the children of God, and all the world shall be made to know their excellency and the value God has for them. [3.] It will add much to their comfort, very much to their honour, when they are dignified with the tokens of God's favour in that very place where they had long lain under the tokens of his displeasure. This speaks comfort to the believing Gentiles, that they need not go up to Jerusalem, to be received and owned as God's children; no, they may stay where they are, and in that place, though it be in the remotest corner of the earth, in that place where they were at a distance, where it was said to them, "You are not God's people," but are separated from them (Isa. lvi. 3, 6), even there, without leaving their country and kindred, they may by faith receive the Spirit of adoption, witnessing with their spirits that "they are the children of God."
