Humility and suffering free a man from all sin; for the first cuts out spiritual passions, and the latter bodily.

He who is a beginner on the way must not be brought to practise the commandments by kindness alone, but must more often be induced to continue the struggle by being rigorously reminded of God's judgment. In this way he will not only be moved by love to desire what is divine, but will be moved by fear to avoid what is evil. For 'I will sing to Thee, O Lord, of mercy and judgment' (Ps. 101:1 LXX). He will sing to God charmed by love, and steeled by fear he will have strength for the song.

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).

When a man's intellect is constantly with God, his desire grows beyond all measure into an intense longing for God and his incensiveness is completely transformed into divine love. For by continual participation in the divine radiance his intellect becomes totally filled with light; and when it has reintegrated its passible aspect, it redirects this aspect towards God, filling it with an incomprehensible and intense longing for Him and with unceasing love, thus drawing it entirely away from worldly things to the divine.

Theology without practice is the theology of demons

For him who is perfect in love and has reached the summit of dispassion there is no difference between his own or another's, or between Christians and unbelievers, or between slave and free, or between male and female. But because he has risen above the tyranny of the passions and has fixed his attention on the single nature of man, he looks on all in the same way and shows the same disposition to all. For in him there is neither Greek nor Jew, male nor female, bond not free, but Christ who 'is all, and in all' (Col. 3:11; cf. Gal. 3:28).

Inasmuch as you pray with all your soul for the one who has slandered you, so much will God reveal the truth to them who have believed the slander.
