I. Christ brings the Supernatural Communication of a New Life.
We may fairly regard this metaphor as setting forth the very deepest characteristic of the gospel. Consider man's need, as typified in the image of the desert. Mark that the supply for that need must come from without; that coming from without, it must be lodged in the heart of the race; that the supernatural communication of a new life and power is the very essence of the work of Christ; that such a communication is the only thing adequate to produce these wondrous effects.
II. This new life slakes men's thirst.
The pangs and tortures of the waterless wilderness. The thirst of human souls; they long, whether they know it or not, for—
Truth for Understanding.
Love for Heart.
Basis and Guidance for Will and Effort.
Cleansing for Conscience.
Adequate objects for their powers.
They need that all these should be in One.
The gnawing pain of our thirst is not a myth; it is the secret of man's restlessness. We are ever on the march, not only because change is the law of the world, nor only because effort and progress are the law for civilised men, but because, like caravans in the desert, we have to search for water.
In Christ it is slaked; all is found there.
III. The Communication of this New Life turns Illusions into Realities.
'The mirage shall become a pool.' Life without Christ is but a long illusion. 'Sin makes a mock of fools.' How seldom are hopes fulfilled, and how still less frequently are they, when fulfilled, as good as we painted them! The prismatic splendours of the rain bow, which gleam before us and which we toil to catch, are but grey rain-drops when caught. Joys attract and, attained, have incompleteness and a tang of bitterness. The fish is never so heavy when landed on the sward as it felt when struggling on our hook. 'All is vanity'—yes, if creatures and things temporal are pursued as our good. But nothing is vanity, if we have the life in us which Jesus comes to give. His Gospel gives solid, unmingled joys, sure promises which are greater when fulfilled than when longed for, certain hopes whose most brilliant colours are duller than those of the realities. The half has not been told of the 'things which God hath prepared for them that love Him.'
