Whatever a man loves he inevitably clings to, and in order not to lose it he rejects everything that keeps him from it. So he who loves God cultivates pure prayer, driving out every passion that keeps him from it. He who drives out self-love, the mother of the passions, will with God's help easily rid himself of the rest, such as anger, irritation, rancor and so on. But he who is dominated by self-love is overpowered by the other passions, even against his will. Self-love is the passion of attachment to the body.
No benefit comes from a just man's prayer if he who asks for it finds more pleasure in sin than in virtue. For Samuel mourned over Saul when he sinned, but he was not able to obtain God's mercy, for his grief was not supported by the necessary change of life on the part of the sinner. Hence God put an end to the pointless grief of His servant, saying to him, 'How long will you mourn for Saul, seeing I have rejected him from reigning over Israel?' (I Sam. 16:1).
