You are aware, perhaps, that if you scratch the skin, and introduce a little diseased animal matter to the blood, it will gradually spread itself through the system, and in time poison the whole body. And if you do not know this, you know, that if you take a little leaven, and place it in a mass of meal, and leave it there to work unchecked, it will in time leaven the whole lump. And as it is with things natural, so it is with things spiritual. If you allow a little leaven of bad feeling to get into your minds towards your fellow Christians or your brother ministers, and permit it to remain there, it will in time infect your whole soul, impair the action of all its faculties, and after alienating you from individuals, separate you first from the Church, and then from Christ and Christianity. There is a passage in the Bible which says that judges are not to take gifts; and the reason assigned is, not that if a judge accepts a present he will, with his eyes open, wilfully condemn the innocent or acquit the guilty; but that "a gift _blindeth the eyes_," even "of the wise," so that he is no longer able to see clearly which is the guilty and which the guiltless party. And there is another passage in the Bible which says that "oppression driveth a wise man mad." The feeling a man has that he has been wickedly, cruelly treated, excites his mind so painfully and violently, that it is impossible for him to think well of the character or views of his oppressor, or of any party, institution, or system with which he may be connected. As some friends of mine were canvassing for votes one day, previous to an election, they came upon a man who could not, for a time, say for which candidate he would vote. At length a thought struck him, and he said, "Who is John Myers going to vote for?" "Oh," said my friends, "he's going to vote for _our_ man." "Then I'll vote for the other man," said he, "for I'm sure Myers will vote wrong." Myers had swindled him in a business transaction; and his feelings towards him were so strong, and of so unpleasant a kind, that he could not think anything right that Myers did, nor could he think anything wrong that he himself did, so long as he took care to go contrary to Myers.
