How often, and how sadly this has been the case; how often and how deeply individuals and churches have been injured from this cause, no one is ignorant. Families and nations, as well as individuals, have experienced the dreadful effects of the displeased and angry feelings, when they are not overruled and kept in check by true piety. The history of the world, from its earliest periods, is a solemn and monitory lesson on this subject. "He, that is slow to anger, is better than the mighty; and he that ruleth his spirit, than he that taketh a city." There seems to be need of greater effort and of more faith and prayer, to regulate entirely this department of the Affections, (usually denominated the Malevolent Affections,) than is required in the regulation of the other. But the grace of God is sufficient even here.
