These _pro tem._ believers are indigenous to every soil. There never is a great movement afloat--philanthropic, political or spiritual--but numberless smaller craft are lifted up on its swell. For a moment they seem instinct with life, but having no propelling power in themselves, they drop behind, soon to be embedded in the mire. And especially is this true in the region of spiritual dynamics. In all so-called "revivals" of religion, when the Church rejoices in a deepened and quickened life, when a cooling zeal has been rewarmed at the heavenly fires, and converts are multiplied, in the accessions which follow almost invariably will be found a proportion of what we may call "casuals." We cannot say they are counterfeits, for the work, as far as it goes, seems real, and the change, both in their thought and life, is clearly marked. But they are unstable souls, prone to drifting, their direction given in the main by the set of the current in which they happen to be. And so when they reach the point--which all must reach sooner or later--where two seas meet, the cross current of enticement and temptation bears hard upon them, and they make shipwreck of faith. Others, again, are led by impulse. Religion with them is mainly a matter of feeling. Overlooking the fact that the emotions are easily stirred, that they respond to the passing breath just as the sea ripples to the breeze, they substitute emotion for conviction, feeling for faith. But these have no foundation, no root, no independent life, and when the excitements on which they feed are withdrawn, when the emotion subsides, the high tide of fervour falling back to its mean sea-level, they lose heart and hope. They are even ready to pity themselves as the objects of an illusion. But the illusion was one of their own making. They set the pleasant before the right, delight before duty, comfort before Christ, and instead of finding their heaven in doing the will of God, no matter what the emotions, they sought their heaven in their own personal happiness, and so they missed both. "They endure for a while." And of how many are these words true! Verily we must not count our fruits from the blossoms of spring, nor must we reckon our harvest in that easy, hopeful way of multiplying each seed, or even each blade, by the hundredfold, for the blade may be only a short-lived blade and nothing more.
