We see that water gravitates from the mountains to low-lying areas; so too, the grace of God is poured out from the Heavenly Father upon humble hearts.
Without humility no other virtue is possible, for if man does not fulfill virtue in a spirit of humility, he will inevitably fall into God-opposing pride, and will fall away from God’s mercy.
Our enemies (demons) fell because of their pride, and call us to follow them, and bring us feelings of praise. And if your soul accepts that praise, then grace will depart, until the soul becomes humble again. And so all your life you must learn the humility of Christ.
If we cut off the causes of the passions for only a short while, and occupy ourselves with spiritual contemplation without making it our sole and constant concern, we easily revert to the passions of the flesh, gaining nothing from our labor but theoretical knowledge coupled with conceit. The result is a gradual darkening of this knowledge itself and a complete turning of the intellect towards material things.
It is not the clever, the noble, the polished speakers, or the rich who win, but whoever is insulted and forebears, whoever is wronged and forgives, whoever is slandered and endures, whoever becomes a sponge and mops up whatever they might say to him. Such a person is cleansed and polished even more. He reaches great heights. He delights in the theoria of mysteries. And finally, it is he who is already inside paradise, while still in this life.
We are told to draw the waters of life from the sources of the Divine Writings which alone can extinguish the passions that plague us and set us on the road to intellectual truth.
No man, wise in his own opinion, because he has studied all the sciences and is learned in external wisdom, will ever penetrate God's mysteries or see them unless he first humbles himself and becomes foolish in his heart, repudiating his self-opinion together with his acquirements of learning. For a man who acts thus and follows with undaunted faith those who are wise in things Divine, is guided by them and with them enters into the city of the living God, and, taught and enlightened by the Holy Spirit, sees and knows things which no one else can see or know. Thus he becomes taught of God.
The humility which in due time and by God's grace, after many struggles and tears, is given by heaven to those who seek it is something incompararably stronger and higher than the sense of abasement felt by those who have lapsed from holiness. This higher humility is granted only to those who have attained true perfection and are no longer under the sway of sin.
The best medicine for pride, man’s greatest sickness of soul, is humility. Words cannot describe or explain it, but the Fathers say that he who strives hard to live according to the precepts of our Lord, and is fully aware of his own sins, acquires it steadily. Therefore be very careful never to think yourself good, or the least bit better than others.
