First of all, Christ needs no new inventions to glorify Him. “We have invented a new line of things,” says one. Have you? “We have discovered something very wonderful.” I daresay you have, but Christ, “the same yesterday, and today, and for ever” (Heb. 13:8 ) needs none of your inventions, discoveries, or additions to His truth. A plain Christ is forever the loveliest Christ. Dress Him up, and you have 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” (1 Cor. 1:23); indeed, you cannot have Christ without the Cross; but preach Christ crucified, and you have given him all the glory that He desires. The Holy Spirit does not reveal in these last times any fresh laws or any novel doctrines or any new evolutions. He simply brings to mind the things that Christ Himself spoke. He brings Christ’s own things to us, and in that way glorifies Him.
