See here, 1. To how great a degree a good man will be merciful; he has not only a compassion for the human nature under its greatest abasements, but he regards even the life of his beast, not only because it is his servant, but because it is God's creature, and in conformity to Providence, which preserves man and beast. The beasts that are under our care must be provided for, must have convenient food and rest, must in no case be abused or tyrannised over. Balaam was checked for beating his ass. The law took care for oxen. Those therefore are unrighteous men that are not just to the brute-creatures; those that are furious and barbarous to them evidence, and confirm in themselves, a habit of barbarity, and help to make the creation groan, Rom 8:22. 2. To how great a degree a wicked man will be unmerciful; even his tender mercies are cruel; that natural compassion which is in him, as a man, is lost, and, by the power of corruption, is turned into hard-heartedness; even that which they will have to pass for compassion is really cruel, as Pilate's resolution concerning Christ the innocent, I will chastise him and let him go. Their pretended kindnesses are only a cover for purposed cruelties.
