Note the distinction between doing the will and perfecting the work. That implies that Jesus Christ, like us, reached forward, in each successive act of obedience to the successive manifestations of the Father's will, to something still undone. The work will never be perfected or finished except on condition of continual fulfilment, moment by moment, of the separate behests of that divine will. For the Lord, as for His servants, this was the manner of obedience, that He 'pressed towards the mark,' and by individual acts of conformity secured that at last the whole 'work' should have been so completely accomplished that He might be able to say upon the Cross, 'It is finished.' If we have any right to call ourselves His, we too have thus to live.
III. Lastly, notice the reinvigorated Christ.
I have already pointed out the lovely contrast between the two pictures, the beginning and the end of this incident; so I need not dwell upon that. The disciples wondered when they found that Christ desired and needed none of the homely sustenance that they had brought to Him. And when He answered their sympathy rather than their curiosity—for they did not ask Him any questions, but they said to Him, 'Master, eat'—with 'I have meat to eat that ye know not of,' they, in their blind, blundering fashion, could only imagine that some one had brought Him something. So they gave occasion for the great words upon which we have been touching.
Notice, however, that Christ here sets forth the lofty aim at conformity to the divine will and fulfilment of the divine Work as being the meat of the soul. It is the true food for us all. The spirit which feeds upon such food will grow and be nourished. And the soul which feeds upon its own will and fancies, and not upon the plain brown bread of obedience, which is wholesome, though it be often bitter, will feed upon ashes, which will grate upon the teeth and hurt the palate. Such a soul will be like those wretched infants that are discovered sometimes at 'baby-farms,' starved and stunted, and not grown to half their right size. If you would have your spirits strong, robust, well nourished, live by obedience, and let the will of God be the food of your souls, and all will be well.
Souls thus fed can do without a good deal that others need. Why, enthusiasm for anything lifts a man above physical necessities and lower desires, even in its poorest forms. A regiment of soldiers making a forced march, or an athlete trying to break the record, will tramp, tramp on, not needing food, or rest, or sleep, until they have achieved their purpose, poor and ignoble though it may be. In all regions of life, enthusiasm and lofty aims make the soul lord of the body and of the world.
And in the Christian life we shall be thus lords, exactly in proportion to the depth and earnestness of our desires to do the will of God. They who thus are fed can afford 'to scorn delights and live laborious days.' They who thus are fed can afford to do with plain living, if there be high impulses as well as high thinking. And sure I am that nothing is more certain to stamp out the enthusiasm of obedience which ought to mark the Christian life than the luxurious fashion of living which is getting so common to-day amongst professing Christians.
It is not in vain that we read the old story about the Jewish boys whose faces were radiant and whose flesh was firmer when they were fed on pulse and water than on all the wine and dainties of the Babylonish court. 'Set a knife to thy throat if thou be a man given to appetite,' and let us remember that the less we use, and the less we feel that we need, of outward goods, the nearer do we approach to the condition in which holy desires and lofty aims will visit our spirits.
