…that apostolical benediction, wherein the communication of spiritual blessings from the several persons unto the saints is so exactly distinguished; it is grace that is ascribed to our Lord Jesus Christ, 2 Cor. 13:14, “The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Ghost, be with you all.“
Yea, Paul is so delighted with this, that he makes it his motto, and the token whereby he would have his epistles known, 2 Thess. 3:17, 18, “The salutation of Paul with mine own hand, which is the token in every epistle: so I write. The grace of our Lord Jesus Christ be with you all.” Yea, he makes these two, “Grace be with you,” and, “The Lord Jesus be with you,” to be equivalent expressions; for whereas he affirmed the one to be the token in all his epistles, yet sometimes he useth the one only, sometimes the other of these, and sometimes puts them both together. This, then, is that which we are peculiarly to eye in the Lord Jesus, to receive it from him, even grace, gospel-grace, revealed in or exhibited by the gospel. He is the head-stone in the building of the temple of God, to whom “Grace, grace,” is to be cried, Zech. 4:7.
