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.
