The person who loves God cannot help loving every man as himself, even though he is grieved by the passions of those who are not yet purified. But when they amend their lives, his delight is indescribable and knows no bounds.
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).
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.
We must not only put bodily passions to death but also destroy the soul's impassioned thoughts. Hence the Psalmist says, 'Early in the morning I destroyed all the wicked of the earth, that I might cut off all evil-doers from the city of the Lord' (Ps. 101:8) - that is, the passions of the body and the soul's godless thoughts.
Humility and ascetic hardship free a man from all sin, for the one cuts out the passions of the soul, the other those of the body. This is what the blessed David indicates when he prays to God, saying, "Look on my humility and my toil, and forgive all my sins" (Ps. 25:18).
...the Lord said as He drew near His passion, 'Now is the Son of man glorified, and God is glorified in Him. If God is glorified in Him, God will also glorify Him in Himself; and He will glorify Him at once' (Jn. 13:31-32). From This it is clear that divine gifts follow sufferings endured for the sake of virtue.
