20. Nay, the Godhead itself is so infinitely above us, that, in itself, it is inaccessible; and it is ready to amaze and overwhelm us, to think of coming to the incomprehensible Majesty: but it emboldeneth the soul, to think of our glorified nature in Christ, and that, even in heaven, God will everlastingly condescend to us in the Mediator. For the mediation of redemption and acquisition shall be ended, (and thus he shall deliver up the kingdom to the Father,) yet it seems that a mediation of fruition shall continue: for Christ said to his Father, "I will that they also whom thou hast given me, be with me where I am, that they may behold my glory," John xvii. 24. We shall "rejoice," when the "marriage of the Lamb is come," Rev. xix. 7. "They are blessed that are called to his marriage supper," ver. 9. "The Lord God Almighty and the Lamb are the temple and the light of the new Jerusalem," Rev. xxi. 22, 23. Heaven would not be so familiar, or so sweet to my thoughts, if it were not that our glorified Lord is there, in whose love and glory we must live for ever. O christian, as ever thou wouldst walk with God in comfortable communion with him, study and exercise this life of faith, in the daily use and improvement of Christ, who is our life, and hope, and all. [Sidenote: To believe in the Holy Ghost, and live upon his grace.] _Grand Direct._ III. Understand well what it is to believe in the Holy Ghost; and see that he dwell and operate in thee, as the life of thy soul, and that thou do not resist or quench the Spirit, but thankfully obey him. Each person in the Trinity is so believed in by christians, as that in baptism they enter distinctly into covenant with them: which is, to accept the mercies of, and perform the duties to, each person distinctly.[88] As to take God for our God is more than to believe that there is a God, and to take Christ for our Saviour is more than barely to believe that he is the Messiah; so to believe in the Holy Ghost, is to take him for Christ's agent or advocate with our souls, and for our Guide, and Sanctifier, and Comforter, and not only to believe that he is the third person in the Trinity. This therefore is a most practical article of our belief. If the blasphemy against the Holy Ghost be the unpardonable sin, then all sin against the Holy Ghost must needs have a special aggravation by being such. And if the sin against the Holy Ghost be the greatest sin, then our duty towards the Holy Ghost is certainly none of our smallest duties. Therefore the doctrine of the Holy Spirit, and our duty towards him, and sin against him, deserve not the least or last place in teaching, learning, and most serious consideration.
