Unhappily, in the case of the reformer, his most dangerous foes are those of his own household. True, the world's garden has become a desert and needs renovation; but is his own little nook weedless? Sin abounds without; but is his own heart pure? While smiting down the giants and dragons which beset the outward world, are there no evil guests sitting by his own hearth-stone? Ambition, envy, self-righteousness, impatience, dogmatism, and pride of opinion stand at his door-way ready to enter whenever he leaves it unguarded. Then, too, there is no small danger of failing to discriminate between a rational philanthropy, with its adaptation of means to ends, and that spiritual knight-errantry which undertakes the championship of every novel project of reform, scouring the world in search of distressed schemes held in durance by common sense and vagaries happily spellbound by ridicule. He must learn that, although the most needful truth may be unpopular, it does not follow that unpopularity is a proof of the truth of his doctrines or the expediency of his measures. He must have the liberality to admit that it is barely possible for the public on some points to be right and himself wrong, and that the blessing invoked upon those who suffer for righteousness is not available to such as court persecution and invite contempt; for folly has its martyrs as well as wisdom; and he who has nothing better to show of himself than the scars and bruises which the popular foot has left upon him is not even sure of winning the honors of martyrdom as some compensation for the loss of dignity and self-respect involved in the exhibition of its pains. To the reformer, in an especial manner, comes home the truth that whoso ruleth his own spirit is greater than he who taketh a city. Patience, hope, charity, watchfulness unto prayer,--how needful are all these to his success! Without them he is in danger of ingloriously giving up his contest with error and prejudice at the first repulse; or, with that spiteful philanthropy which we sometimes witness, taking a sick world by the nose, like a spoiled child, and endeavoring to force down its throat the long-rejected nostrums prepared for its relief.
