Chapter 28 — Part III: The Decalogue — The Fifth Commandment
Section 34. Disadvantages Of Revenge — Finally, the disadvantages which arise from the refusal to pardon others are to be explained. The pastor, therefore, should place before the eyes of the unforgiving man that hatred is not only a grievous sin, but also that the longer it is indulged the more deeply rooted it becomes. The man, of whose heart this passion has once taken possession, thirsts for the blood of his enemy. Filled with the hope of revenge, he will spend his days and nights brooding over some evil design, so that his mind seems never to rest from malignant projects, or even from thoughts of blood. Thus it follows that never, or at least not without extreme difficulty, can he be induced generously to pardon an offence, or even to mitigate his hostility. Justly, therefore, is hatred compared to a wound in which the weapon remains firmly embedded.
