Quotes from the Saints
The Four Hundred Chapters on Love:
210. When a person loves someone, he is naturally eager to be of service. So if one loves God, he is naturally eager to do what is pleasing to him. But if he loves his flesh, he is eager to accomplish what delights it.
212. When the mind inclines toward God, it keeps the body as a servant and allows it nothing more that what is necessary for life. But when it inclines toward the flesh, it becomes a servant of the passions and always makes provision for its lusts.
213. If you want to prevail over your thoughts, take care of your passions and you will easily drive them from your mind. Thus for fornication, fast, keep vigil, work hard, keep to yourself. For anger and hurt, pray for the one who has hurt you and you will be rid of them.
St. Maximus the Confessor
