The third sort of soil brings things still farther on before failure comes. The seed is not only covered and germinating, but has actually begun to be fruitful. The thorns are supposed to have been cut down, but their roots have been left, and they grow faster than the wheat. They take the 'goodness' out of the ground, and block out sun and air; and so the stalks, which promised well, begin to get pale and droop, and the half-formed ear comes to nothing, or, as the other version of the parable has it, brings 'forth no fruit to perfection.' There are two crops fighting for the upper hand on the one ground, and the earlier possessor wins. The 'struggle for existence' ends with the 'survival of the fittest'; that is, of the worst, to which the natural bent of the desires and inclinations of the unrenewed man is more congenial. The 'cares of this world' and the 'deceitfulness of riches' are but two sides of one thing. The poor man has cares; the rich man has the illusions of his wealth. Both men agree in thinking that this world's good is most desirable. The one is anxious because he has not enough of it, or fears to lose what he has; the other man is full of foolish confidence because he has much. Eager desires after creatural good are common to both; and, what with the anxiety lest they lose, and the self-satisfaction because they have, and the mouths watering for the world's good, there is no force of will, nor warmth of love, nor clearness of vision, left for better things. That is the history of the fall of many a professing Christian, who never apostatises, and keeps up a reputable appearance of godliness to the end; but the old worldliness, which was cut down for a while, has sprung again in his heart, and, by slow degrees, the word is 'choked'--a most expressive picture of the silent, gradual dying-out of its power for want of sun and air--and 'he' or 'it' 'becometh unfruitful,' relapsing from a previous condition of fruit-bearing into sterility. No heart can mature two crops. We must choose between God and Mammon--between the word and the world.
