Quotes from the Saints
The Four Hundred Chapters on Love:
240. The mind of the one who loves God does not engage in battle against things nor against their representations, but against the passions joined to these representations. Thus it does not war against the woman nor against the one who offends him, nor against their images, but against the passions that are joined to these images.
248. In everything that we do God looks at the intention, as has frequently been said, whether we do it for him or for any other motive. Therefore when we wish to do something good, let us not have human applause in view but rather God, so that always looking to him we might do everything on his account; otherwise we shall undergo the labor and still lose the reward.
250. If we sincerely love God we cast out the passions by this very love. Love for him means to prefer him to the world and the soul to the body. It means to despise worldly things and to devote onself continually to him through self-mastery, love, prayer, psalmody, and so forth.
St. Maximus the Confessor
