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.
The more wood you pile on a fire the more heat you get, and thus it is with God - the more you think on Him the more you are fired with love and fervor towards Him. He who loves the Lord is always mindful of Him, and remembrance of God begets prayer.
When you are praying alone, and your spirit is dejected, and you are wearied and oppressed by your loneliness, remember then, as always, that God the Trinity looks upon you with eyes brighter than the sun; also all the angels, your own Guardian Angel, and all the Saints of God. Truly they do; for they are all one in God, and where God is, there are they also. Where the sun is, thither also are directed all its rays. Try to understand what this means.
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.
Only to the humble does the Lord reveal Himself in the Holy Spirit, but if we do not humble ourselves we shall not see God. Humility is the light in which we may behold the Light which is God, as the Psalmist sang: 'In Thy light we shall see light.'
When the first order of angels fell from the angelic glory and became demons, the other nine orders humbled themselves and worshipped the All-holy Trinity, and remained in their place and rejoice forever. We, too, my brethren, must reflect what an evil thing pride is - that it cast down the devil from angelic glory and he will always burn in Hell - and that humility kept the angels in Heaven, and they rejoice perpetually in the glory of the Holy Trinity. Let us then, my brethren, avoid pride, because it is the first daughter of the devil, is a path that leads to Hell; and let us have humility, because it is angelic—it is a path that leads to Paradise.
An Athonite elder said, 'Blasphemous thoughts are like airplanes that annoy us, against our will, with their noise, and we are powerless to prevent them. The heavy anti-aircraft battery is psalmody, because it is both prayer to Christ and disdain for the devil.'
If you refuse to accept suffering and dishonor, do not claim to be in a state of repentance because of your other virtues. For self-esteem and insensitivity can serve sin even under the cover of virtue.
The Saints in Heaven through the Holy Spirit behold the glory of God and the beauty of the Lord's Countenance. But in this same Holy Spirit they see our lives too, and our deeds. They know our sorrows and hear our burning prayers. When they were living on earth they learned of the love of God from the Holy Spirit: and he who knows love on earth takes it with him into eternal life in the Kingdom of Heaven, where love grows and becomes perfect. And if love makes one unable to forget a brother here, how much more must the Saints remember and pray for us!
The Martyrs won Paradise through their blood; the Ascetics, through their ascetic life. Now you, my brethren, who have children, how will you win Paradise? By means of hospitality, by giving to your brothers who are poor, blind, or lame.
It is a great good to give oneself up to the will of God. Then the Lord alone is in the soul. No other thought can enter in, and the soul feels God's love, even though the body be suffering.
This prayer should never be absent from you: 'Lord Jesus Christ, Son and Logos of the living God, through the Theotokos and all the Saints, have mercy upon me, Thy sinful and unworthy servant.' (This is the actual Jesus Prayer: 'O LORD JESUS CHRIST, SON OF GOD, HAVE MERCY UPON ME, A SINNER.') Always say this prayer both with your mouth and with your mind, day and night, wherever you may be, whether eating, walking, working, or sitting. Always meditate on it, as it benefits you a great deal, frees you here from every evil, delivers you there from eternal Hell, and renders you worthy of going to Paradise, our heavenly country.
Therefore with your whole soul you should acknowledge yourself as worthy of enduring more than you already endure; remember the words which Christ the Savior spoke concerning a good deed done to one's neighbor, words which should apply equally to every offensive word or deed against one's neighbor. Whatever you have done to your neighbor, He says, you have done to Me.
