The more a man's tongue flees verbosity, the more his intellect is illumined so as to be able to discern deep thoughts; for the rational intellect is befuddled by verbosity.
As a man cannot remain unscathed who spares his enemy on the field of battle, so a man engaged in spiritual warfare cannot save his soul if he spares his body.
The man who is conscious of his sins is greater than he who profits the whole world by the sight of his countenance. The man who sighs over his soul for but one hour is greater than he who raises the dead by his prayer while dwelling amid many men.
As it is not possible to cross over the great ocean without a ship, so no one can attain to love without fear. The fetid sea, which lies between us and the noetic paradise, we may cross by the boat of repentance, whose oarsmen are those of fear. But if fear's oarsmen do not pilot the ship of repentance whereby we cross over the sea of this world to God, we shall be drowned in the fetid abyss. Repentance is the ship and fear is the pilot; love is the divine haven.
The first duty of a Christian, of a disciple and follower of Jesus Christ, is to deny oneself. To deny oneself means to give up one's bad habits, to root out of the heart all that ties us to the world; not to cherish bad desires and thoughts; to quench and suppress bad thoughts; to avoid occasions of sin; not to do or desire anything from self-love but to do everything out of love for God. To deny oneself means, according to the Apostle Paul, to be dead to sin and the world, but alive to God.
Whenever in your path you find unchanging peace, beware: you are very far from the divine paths trodden by the weary feet of the saints. For as long as you are journeying in the way to the city of the Kingdom and are drawing near the city of God, this will be a sign for you: the strength of the temptations that you encounter. And the nearer you draw close and progress, the more temptations will multiply against you.
Faith and love which are gifts of the Holy Spirit are such great and powerful means that a person who has them can easily, and with joy and consolation, go the way Jesus Christ went. Besides this, the Holy Spirit gives man the power to resist the delusions of the world so that although he makes use of earthly good, yet he uses them as a temporary visitor, without attaching his heart to them. But a man who has not got the Holy Spirit, despite all his learning and prudence, is always more or less a slave and worshipper of the world.
Not every man is wakened to wonder by what is said spiritually and has great power concealed in it. A word concerning virtue has need of a heart unbusied with the earth and its converse.
If you have no works, do not speak on virtues. Afflictions suffered for the Lord's sake are more precious to Him than every vow and sacrifice; and the odor of their sweet surpasses every fragrance.
