Acts of charity, almsgiving and all the external good works do not suppress the arrogance of the heart; but noetic meditation, the labor of repentance, contrition and humility -- these humble the proud mind.
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.
How are we to come to this saving humility, leaving behind us the deadly swelling of arrogance? By exercising ourselves in it in all things, and by keeping in mind that there is nothing which cannot be a danger to us. For the soul becomes like the things it gives itself to; and takes the character and appearance of what it does. Let your demeanor, your dress, your walking, your sitting down, the nature of your food, the quality of your bed, your house and what it contains aim at simplicity. And let your speech, your singing, your manner with your neighbor, let these things also be more in accord with humility than with vanity. In your words let there be no empty pretence, in your singing no excessive sweetness, in conversation be not ponderous or overbearing. In everything refrain from seeking to appear important. Be a help to your friends, kind to the ones who live with you, gentle to your servant, patient with those who are troublesome, loving towards the lowly, comforting to those in trouble, visiting those in affliction, never despising anyone, gracious in friendship, cheerful in answering others, courteous, approachable to everyone, never speaking your own praises, nor getting others to speak them, never taking part in unbecoming conversation, and concealing where you may whatever gifts you possess.
If therefore holy men, even when they do mighty things, think themselves worthless, what must be said of those who, without fruit of virtue, are yet swollen with pride? But any works, although they be good, are as nothing unless seasoned with humility. A great deed done boastfully, lowers rather than uplifts a man. He who would gather virtue without humility, carries dust in the wind; and where he seems to possess something, from the same is he blinded and made worse.
The virtue opposed to pride is humility. But as far as pride is loathsome and abominable, so welcome and lovely is humility to God and men. God Who is great and exalted looks on nothing so lovely as on an humble and compunctionate heart. Whence even the Most Holy Theotokos says of herself, For He hath regarded the low estate of His handmaiden. (Luke 1:48).
Whence is it that we are Christians? Through our faith, would be the universal answer. And in what way are we saved? Plainly because we were regenerate through the grace given in our baptism.
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.
In so much as you sincerely compel yourself to do God's commandments, an understanding of the infirmity of your being will be born in you, and in as much as you have this understanding, one of the basic Christian virtues, humility, will in turn be born. God's grace is given only for humility, not for works, although humility is engendered by works. This is the law of true asceticism.
The Lord does not reveal Himself to many because of their intellectual pride; yet they think that they have much knowledge. But what is their knowledge worth, if they know not the Lord, know not the grace of the Holy Spirit, know not how this grace comes and wherefore it is lost? But let us humble ourselves, brethren, and the Lord will show us all things, as a loving father shows all things to his children.
When we are incapable of scaling the peaks of virtue, all we have to do is to descend into the ravine of humility. Our humility is our surest intercessor before the face of the Lord.
As soon as a man becomes humble, mercy is not slow to envelop him. Then the heart is aware of God’s help, and acquires a certain power of assurance (in God) which arises in it. And when a man is aware that God’s help is actually assisting him, his heart becomes filled with faith in very truth.
