And now that it is a Covenant of Grace, will appear, if we consider with whom this Covenant was primarily made; and that was with Jesus Christ, it was made between God in the Person 1of the Father, and Man in the Person of Christ. Our Lord Jesus was constituted in this Covenant, the great Head, Representative, and blessed Surety, for and in behalf of all the Father gave unto him. Adam had no Surety that undertook for him in the first Covenant, as a Covenanting Hand, but was entrusted with all his Riches, all being put into his own Hand, which he soon by his Sin lost, and undid himself and all his Posterity, whom he was set up as the common Head and Representative of. God foreseeing this, he would not enter into a Covenant any more with Man, his Credit being for ever lost: And since he lost all when he had Power to stand, there was no likelihood or possibility of his standing, after he had deprived himself of his Power of doing good, being depraved in all the Faculties of his Soul. Therefore Christ was set up, set up from Everlasting, by the Holy God, (who foresaw all things before they came to pass) as the Head and Surety of the New Covenant, (called the New Covenant, in respect had to the time of the Revelation of it to Mankind, it being not known until Man had broke the first Covenant): now Christ undertook in the Covenant of Grace for all the Elect, he personating them, when the Father and he entered into that glorious Compact or Covenant-Transactions, we having not then an actual Being, he represented all that were given to him out of the lost Lump of fallen Man; and undertook, as Mediator, to make up that Breach that was between God and Man; and by his perfect Obedience to merit for them Everlasting Life, and to bring them all to Glory. ⟨p. 203⟩This being so, nothing can more fully demonstrate the Certainty of their Salvation, and the Impossibility of any of their perishing; for they for whom Jesus Christ did undertake this great and glorious Work, even all the Elect Seed, were put into his Hand by the Tenor of this Covenant, to work out Life and Salvation for them, and to die in the room and stead of them; thereby to bear that Wrath and Curse that they otherwise must have suffered, born and endured for ever.
