“If He had not threatened hell, if He had not   prepared punishment, there are not many who would have attained the   kingdom. [1349] For the promise of good things doth not so strongly   induce the multitude to virtue; as doth the threat of evil things   compel by fear, and arouse them to the care of the soul.”
(St. John Chrysostom)
