And so there has to be something like an eye given to these blind beasts, and something like a directing hand laid upon these instinctive impulses. The true temple of the human spirit must be built in stages, the broad base laid in these animal instincts; above them, and controlling them, the directing and restraining will; above it the understanding which enlightens it and them; and supreme over all the conscience with nothing between it and heaven. Where that is not the order of the inner man you get wild work. You have set 'beggars on horseback,' and we all know where they go! The man who lets passion and inclination guide is like a steam-boat with all the furnaces banked up, with the engines going full speed, and nobody at the wheel. It will drive on to the rocks, or wherever the bow happens to point, no matter though death and destruction lie beyond the next turn of the screw. That is what you will come to unless you live in the habitual exercise of rigid self-control.
And that self-control is to be exercised mainly, or at least as one very important form of it, in regard to our use and estimate of the pleasures of this present life. Yes! it is not only from the study of a man's make that the necessity for a very rigid self-government appears, but the observation of the conditions and circumstances in which he is placed points the same lesson. All round about him are hands reaching out to him drugged cups. The world with all its fading sweet comes tempting him, and the old fable fulfils itself--Whoever takes that Circe's cup and puts it to his lips and quaffs deep, turns into a swine, and sits there imprisoned at the feet of the sorceress for evermore!
There is only one thing that will deliver you from that fate, my brother. 'Be sober,' and in regard to the world and all that it offers to us--all joy, possession, gratification--'set a knife to thy throat if thou be a man given to appetite.' There is no noble life possible on any other terms--not to say there is no Christian life possible on any other terms--but suppression and mortification of the desires of the flesh and of the spirit. You cannot look upwards and downwards at the same moment. Your heart is only a tiny room after all, and if you cram it full of the world, you relegate your Master to the stable outside. 'Ye cannot serve God and Mammon.' 'Be sober,' says Paul, then, and cultivate the habit of rigid self-control in regard to this present. Oh! what a melancholy, solemn thought it is that hundreds of professing Christians in England, like vultures after a full meal, have so gorged themselves with the garbage of this present life that they cannot fly, and have to be content with moving along the ground, heavy and languid. Christian men and women, are you keeping yourselves in spiritual health by a very sparing use of the dainties and delights of earth? Answer the question to your own souls and to your Judge.
II. And now let me turn to the other thoughts that lie here. There is, secondly, a motive which backs up and buttresses this exhortation. 'Let us who are of the day'--or as the Revised Version has it a little more emphatically and correctly, 'Let us, since we are of the day, be sober.' 'The day'; what day? The temptation is to answer the question by saying--'of course the specific day which was spoken about in the beginning of the section, "the day of the Lord," that coming judgment by the coming Christ.' But I think that although, perhaps, there may be some allusion here to that specific day, still, if you will look at the verses which immediately precede my text, you will see that in them the Apostle has passed from the thought of 'the day of the Lord' to that of day in general. That is obvious, I think, from the contrast he draws between the 'day' and the 'night,' the darkness and the light. If so, then, when he says 'the children of the day' he does not so much mean--though that is quite true--that we are, as it were, akin to that day of judgment, and may therefore look forward to it without fear, and in quiet confidence, lifting up our heads because our redemption draws nigh; but rather he means that Christians are the children of that which expresses knowledge, and joy, and activity. Of these things the day is the emblem, in every language and in every poetry. The day is the time when men see and hear, the symbol of gladness and cheer all the world over.
