Perhaps he was referring, in the words of our text, to the break-up of the existing order of things which he discerned as impending and already begun to take effect in consequence of the coming of Jesus Christ, the shining of the true Light. For you may remember that in a previous part of the epistle he uses precisely the same expression, with a significant variation. Here, in our text, he says, 'The world passeth away'; there he says, 'The darkness has passed and the true light now shineth.' He sees a process installed and going on, in which the whole solid-seeming fabric of a godless society is being dissolved and melted away. And says he, in the midst of all this change there is one who stands unchanged, the man that does God's will.

But just for a moment we may take the lower point of view, and see here a flat contradiction of the Preacher. He said, 'Men go, and the world abides.' 'No,' says John; 'your own psalmists might have taught you better: "As a vesture shalt Thou change them, and they shall be changed."' The world, the earth, which seems so solid and permanent, is all the while in perpetual flux, as our later science has taught us, in a sense of which neither Preacher nor Apostle could dream. For just as from the beginning forces were at work which out of the fire-mist shaped sun and planets, so the same forces, continuing in operation, are tending towards the end of the system which they began; and a contracting sun and a diminished light and a lowered temperature and the narrower orbits in which the planets shall revolve, prophesy that 'the elements shall melt with fervent heat,' and that all things which have been made must one day cease to be. Nature is the true Penelope's web, ever being woven and ever being unravelled, and in the most purely physical and scientific sense the world is passing away. But then, because you and I belong, in a segment of our being, to that which thus is passing away, we come under the same laws, and all that has been born must die. So the generations come, and in their very coming bear the prophecy of their going. But, on the other hand, there is an inner nucleus of our being, of which the material is but the transient envelope and periphery, which holds nought of the material, but of the spiritual, and that 'abides for ever.'

But let us lift the thought rather into the region of the true antithesis which John was contemplating, which is not so much the crumbling away of the material, and the endurance of the spiritual, as the essential transiency of everything that is antagonism to the will of God, and the essential eternity of everything which is in conformity with that will. And so, says he, 'The world is passing, and the lust thereof.' The desires that grasp it perish with it, or perhaps, more truly still, the object of the desire perishes, and with it the possibility of their gratification ceases, but the desire itself remains. But what of the man whose life has been devoted to the things seen and temporal, when he finds himself in a condition of being where none of these have accompanied him? Nothing to slake his lusts, if he be a sensualist. No money-bags, ledgers, or cheque-books if he be a plutocrat or a capitalist or a miser. No books or dictionaries if he be a mere student. Nothing of his vocations if he lived for 'the world.' But yet the appetite is abiding. Will that not be a thirst that cannot be slaked?

'The world is passing and the lust thereof,' and all that is antagonistic to God, or separated from Him, is essentially as 'a vapour that appeareth for a little time, and then vanishes away,' whereas the man who does the will of God abideth for ever, in that he is steadfast in the midst of change.

'His hand the good man fastens on the skies,
And lets earth roll, nor heeds its idle whirl.'

He shall 'abide for ever,' in the sense that his work is perpetual. In one very deep and solemn sense, nothing human ever dies, but in another all that is not running in the same direction as, and borne along by the impulse of, the will of God, is destined to be neutralised and brought to nothing at last. There may be a row of figures as long as to reach from here to the fixed stars, but if there is not in front of them the significant digit, which comes from obedience to the will of God, all is but a string of ciphers, and their net result is nothing. And he 'abideth for ever,' in the most blessed and profound sense, in that through his faith, which has kindled his love, and his love which has set in motion his practical obedience, he becomes participant of the very eternity of the living God. 'This is eternal life,' not merely to know, but 'to do the will' of our Father. Nothing else will last, and nothing else will prosper, any more than a bit of driftwood can stem Niagara. Unite yourself with the will of God, and you abide.

And now let me, as briefly as I can, throw together—

III. The plain, practical lessons that come from both these texts.

May I say, without seeming to be morbid or unpractical, one lesson is that we should cultivate a sense of the transiency of this outward life? One of our old authors says somewhere, that it is wholesome to smell at a piece of turf from a churchyard. I know that much harm has been done by representing Christianity as mainly a scheme which is to secure man a peaceful death, and that many morbid forms of piety have given far too large a place to the contemplation of skulls and cross-bones. But for all that, the remembrance of death present in our lives will often lay a cool hand upon a throbbing brow; and, like a bit of ice used by a skilful physician, will bring down the temperature, and stay the too tumultuous beating of the heart. 'So teach us to number our days that we may apply our hearts to wisdom.' It will minister energy, and lead us to say, like our Lord, 'We must work the works of Him that sent Me while it is day; the night cometh.'

Let me say again—a very plain, practical lesson is to dig deep down for our foundations below the rubbish that has accumulated. If a man wishes to build a house in Rome or in Jerusalem he has to go fifty or sixty feet down, through potsherds and broken tiles and triturated marbles, and the dust of ancient palaces and temples. We have to drive a shaft clear down through all the superficial strata, and to lay the first stones on the Rock of Ages. Do not build on that which quivers and shakes beneath you. Do not try to make your life's path across the weeds, or as they call it in Egypt, the 'sudd,' that floats on the surface of the Nile, compacted for many a mile, and yet only a film on the surface of the river, to be swept away some day. Build on God.
