4. All the Promises which were made to the Church of old, of the Messiah as a future Saviour, from that made to our first Parents in Paradise, to that which was delivered by the Prophet Malachi, show it to be impossible that Christ should not have persevered in perfect Holiness. The ancient Predictions given to God's Church, of the Messiah as a Saviour, were of the Nature of Promises; as is evident by the Predictions themselves, and the Manner of delivering them. But they are expressly, and very often called Promises in the New-Testament; as in Luke i.54, 55, 72, 73. Acts xiii.32, 33. Rom. i.1, 2, 3. & Chap. xv.8. Heb. vi.13, &c. These Promises were often made with great Solemnity, and confirmed with an Oath; as in Gen. xxii.16.17. By my self have I sworn, saith the Lord, that in blessing, I will bless thee, and in multiplying, I will multiply thy Seed, as the Stars of Heaven, and as the Sand which is upon the Sea-Shore:— And in thy Seed shall all the Nations of the Earth be blessed. Compare Luke i.72, 73. and Gal. iii.8, 15, 16. The Apostle in Heb. vi.17, 18. speaking of this Promise to Abraham, says, Wherein God willing more abundantly to show to the Heirs of Promise the Immutability of his Counsel, confirmed it by an Oath; that by two IMMUTABLE Things, in which it was IMPOSSIBLE for God to lie, he might have strong Consolation. — In which Words, the Necessity of the Accomplishment, or (which is the same Thing) the Impossibility of the contrary, is fully declared. So God confirmed the Promise of the great Salvation of the Messiah, made to David, by an Oath; Psal. lxxxix.3, 4. I have made a Covenant with my Chosen, I have sworn unto David my Servant; Thy Seed will I establish for ever, and build up thy Throne to all Generations. There is Nothing that is so abundantly set forth in Scripture, as sure and irrefragable, as this Promise and Oath to David. See
