For He shall receive of Mine, and shall shew it unto you. – John 16:14

When the Holy Spirit wants to glorify Christ, what does He do? He does not go abroad for anything, He comes to Christ Himself for that which will be for Christ’s own glory: “He shall glorify Me: for He shall receive of Mine, and shall shew it unto you.” There can be no glory added to Christ; it must be His own glory, which He has already, which is made more apparent to the hearts of God’s chosen by the Holy Spirit.

Christ needs no new inventions to glorify Him. “We have struck out a new line of things,” says one. Have you? “We have found out something very wonderful.” I dare say you have; but Christ, the same yesterday, to-day, and for ever, wants none of your inventions, or discoveries, or additions to His truth. A plain Christ is ever the loveliest Christ. Dress Him up, and you have deformed Him and defamed Him. Bring Him out just as He is, the Christ of God, nothing else but Christ, unless you bring in His cross, for we preach Christ crucified; indeed, you cannot have the Christ without the cross; but preach Christ crucified, and you have given Him all the glory that He wants. The Holy Ghost does not reveal in these last times any fresh ordinances, or any novel doctrines, or any new evolutions; but He simply brings to mind the things which Christ Himself spoke, He brings Christ’s own things to us, and in that way glorifies Him.

Think for a minute of Christ’s person as revealed to us by the Holy Spirit. What can more glorify Him than for us to see His person, very God of very God, and yet as truly man? What a wondrous being, as human as ourselves, but as divine as God! Was there ever another like to him? Never. ~ C.H. Spurgeon
