It is due to neither impotence nor ignorance on God’s part that evils occur in the world, but it is owing to the order of his wisdom and to the greatness of his goodness, whence come the many and divers grades of goodness in things, many of which would be lacking were he to allow no evil to exist. Thus there would be no good of patience without the evil of persecution, nor the good of the preservation of its life in a lion, without the evil of the destruction of the animals on which it lives.
