3. The Covenant of Grace evidences this to us. I shall instance in two famous places; the one is that, A new heart will I give you, and a new spirit will I put within you, I will take away the stony heart out of your flesh, and give you an heart of flesh; I ⟨p. 503⟩will put my Spirit within you, and cause you to walk in my statutes, Ezek. 36. 26, 27. The other is that, I will put my Laws in their inward parts, and write them in their hearts, and will be their God, and they shall be my people, Jer. 31. 33. These Promises do most signally set forth the production of gracious Principles; here's the Principles themselves, a new heart and a new spirit; here's the principal efficient of them, the holy Spirit of God; here's a remotion of the Obstacles unto them, the taking away the heart of stone; here's the next immediate Capacity of receiving them, an heart of flesh; here's the way or manner of producing them, a writing the Law in the heart; here's the effectual fruitfulness of them, a causing to walk in God's statutes; and here's the crown or glory of all, God will be their God and they his people. Now when there is a Worker such as the Almighty Spirit, a Remotion of the Obstacles such as the Stone of hardness, an immediate Capacity such as an Heart of flesh, a way of Working such as the intimate Impression of Truth, a Fruit proceeding such as Obedience to God's Statutes, and a Crown of all such as an Interest in God; How can the Grace be less than insuperable? You ⟨p. 304⟩will say, These Promises were not made to the Gentiles, but to the Jews, and not to any singular persons among them, but to the whole Nation. I answer; These Promises extend not only to the Jews but to the Gentiles; for these are Promises of Grace founded in Christ, and in Christ Jew and Gentile are all one, Gal. 3. 28. so one, that the Gentiles are of the same body and partakers of the promise, Eph. 3. 6. Indeed before the middle Wall of Partition was broken down, they were strangers from the covenant of promise; but that being gone, they are fellow-heirs partaking of the root and fatness of the Olive. Neither do these Promises extend to all the Nation of the Jews, but to the true Israel, the elect People of God, whether they be Jews or Gentiles; for in them only are these Promises fulfilled: Had these been made to all the Jews, the true God would have fulfilled them in every Jew.
