A state so unlike nature, in the ordinary sense of the term, was sure to have its inconveniences. The Christian, even when he had received the gift of the Holy Ghost, was still a man; and as likely as not a man who had to struggle against vanity, folly, ambition, and selfishness of all kinds. His enthusiasm might even seem, in the first instance, to aggravate, instead of removing, his natural faults. It might drive him to speak--for in a primitive church anybody who pleased might speak--when it would have been better for him to be silent. It might lead him to break out in prayer or praise or exhortation, in a style which made the wise sigh. And for those reasons the wise, and such as thought themselves wise, would be apt to discourage the exercise of spiritual gifts altogether. "Contain yourself," they would say to the man whose heart burned within him, and who was restless till the flame could leap out; "contain yourself; exercise a little self-control; it is unworthy of a rational being to be carried away in this fashion." No doubt situations like this were common in the church at Thessalonica. They are produced inevitably by differences of age and of temperament. The old and the phlegmatic are a natural, and, doubtless, a providential, counterweight to the young and sanguine. But the wisdom which comes of experience and of temperament has its disadvantages as compared with fervour of spirit. It is cold and unenthusiastic; it cannot propagate itself; it cannot set fire to anything and spread. And because it is under this incapacity of kindling the souls of men into enthusiasm, it is forbidden to pour cold water on such enthusiasm when it breaks forth in words of fire. That is the meaning of "Quench not the Spirit." The commandment presupposes that the Spirit can be quenched. Cold looks, contemptuous words, silence, studied disregard, go a long way to quench it. So does unsympathetic criticism.
