I am sure I have some such people in my audience, and to them this message comes. You may have, if you will, in your own hearts, a springing fountain of delight and of blessedness which will secure that no unsatisfied desires shall ever torment you. Christ in His fulness, His Spirit, the life that flows from both and is planted within our hearts, these are offered to us all; and if we have them we carry inclosed within ourselves all that is essential to our felicity; and we can say, 'I have learned in whatsoever state I am therewith to be self-satisfying,' not with the proud, stoical independence of a man who does not want either God or man to make him blessed, but with the humble independence of a man who can say 'my sufficiency is of God.'
No independence of externals is possible, nor wholesome if it were possible, except that which comes from absolute dependence on Jesus Christ.
If you have Christ in your heart then life is possible, peace is possible, joy is possible, under all circumstances and in all places. Everything which the soul can desire, it possesses. You will be like the garrison of a beleaguered castle, in the courtyard of which is a sparkling spring, fed from some source high up in the mountains, and finding its way in there by underground channels which no besiegers can ever touch. Sorrows will come, and make you sad, but though there may be much darkness round about you, there will be light in the darkness. The trees may be bare and leafless, but the sap has gone down to the roots. The world may be all wintry and white with snow, but there will be a bright little fire burning on your own hearthstone. You will carry within yourselves all the essentials to blessedness. If you have 'Christ in the vessel' you can smile at the storm. They that drink from earth's fountains 'shall thirst again'; but they who have Christ in their hearts will have a fountain within which will not freeze in the bitterest cold, nor fail in the fiercest heat. 'The water that I shall give him shall be in him a fountain.'
II. Christ's gift is a springing fountain.
The emblem, of course, suggests motion by its own inherent impulse. Water may be stagnant, or it may yield to the force of gravity and slide down a descending river-bed, or it may be pumped up and lifted by external force applied to it, or it may roll as it does in the sea, drawn by the moon, driven by the winds, borne along by currents that owe their origin to outward heat or cold. But a fountain rises by an energy implanted within itself, and is the very emblem of joyous, free, self-dependent and self-regulated activity.
And so, says Christ, 'The water that I shall give him shall be in him a springing fountain'; it shall not lie there stagnant, but leap like a living thing, up into the sunshine, and flash there, turned into diamonds, when the bright rays smile upon it.
So here is the promise of two things: the promise of activity, and of an activity which is its own law.
The promise of activity. There seems small blessing, in this overworked world, in a promise of more active exertion; but what an immense part of our nature lies dormant and torpid if we are not Christians! How much of the work that is done is dreary, wearisome, collar-work, against the grain. Do not the wheels of life often go slowly? Are you not often weary of the inexpressible monotony and fatigue? And do you not go to your work sometimes, though with a fierce feeling of 'need-to-do-it,' yet also with inward repugnance? And are there not great parts of your nature that have never woke into activity at all, and are ill at ease, because there is no field of action provided for them? The mind is like millstones; if you do not put the wheat into them to grind, they will grind each other's faces. So some of us are fretting ourselves to pieces, or are sick of a vague disease, and are morbid and miserable because the highest and noblest parts of our nature have never been brought into exercise. Surely this promise of Christ's should come as a true Gospel to such, offering, as it does, if we will trust ourselves to Him, a springing fountain of activity in our hearts that shall fill our whole being with joyous energy, and make it a delight to live and to work. It will bring to us new powers, new motives; it will set all the wheels of life going at double speed. We shall be quickened by the presence of that mighty power, even as a dim taper is brightened and flames up when plunged into a jar of oxygen. And life will be delightsome in its hardest toil, when it is toil for the sake of, and by the indwelling strength of, that great Lord and Master of our work.
