Brother, it is no exaggeration to say that, when you have summoned up before you the ugliest forms of man's sins that you can fancy, this one overtops them all, because it presents in the simplest form the mother-tincture of all sins, which, variously coloured and perfumed and combined, makes the evil of them all. A heap of rotting, poisonous matter is offensive to many senses, but the colourless, scentless, tasteless drop has the poison in its most virulent form, and is not a bit less virulent, though it has been learnedly distilled and christened with a scientific name, and put into a dainty jewelled flask. 'This is the condemnation, that light is come into the world, and men love darkness rather than light, because their deeds are evil.' I lay that upon the hearts and consciences of some of my present hearers as the key to their rejection or disregard of Christ and His salvation. II. Now, secondly, notice the ascension of Jesus Christ as the pledge and the channel of the world's righteousness--'Because I go to the Father, and ye see Me no more.' He speaks as if the process of departure were already commenced. It had three stages--death, resurrection, ascension; but these three are all parts of the one departure. And so He says: 'Because, in the future, when ye go forth to preach in My name, I shall be there with the Father, having finished the work for which He sent Me; therefore you will convince the world of righteousness.' Now let me put that briefly in two forms. First of all, the fact of an ascended Christ is the guarantee and proof of His own complete fulfilment of the ideal of a righteous man. Or to put it into simpler words, suppose Jesus Christ is dead; suppose that He never rose from the grave; suppose that His bones mouldered in some sepulchre; suppose that there had been no ascension--would it be possible to believe that He was other than an ordinary man? And would it be possible to believe that, however beautiful these familiar records of His life, and however lovely the character which they reveal, there was really in Him no sin at all? A dead Christ means a Christ who, like the rest of us, had His limitations and His faults. But, on the other hand, if it be true that He sprang from the grave because 'it was not possible that He should be holden of it,' and because in His nature there was no proclivity to death, since there had been no indulgence in sin; and if it be true that He ascended up on high because that was His native sphere, and He rose to it as naturally as the water in the valley will rise to the height of the hill from which it has descended, then we can see that God has set His seal upon that life by that resurrection and ascension; and as we gaze on Him swept up heavenward by His own calm power, a light falls backward upon all His earthly life, upon His claims to purity, and to union with the Father, and we say, 'Surely this was a perfectly righteous Man.'
