God often permits virtuous men to be tried by something: He permits temptations to rise up against them on all sides... Whether these trials come from men, demons or flesh, let it be a cause for thanksgiving. For God cannot show his favor to a man who desires to dwell with Him, except by sending him trials for the sake of truth; just as no man can become worthy of this greatness... without the grace of Christ... St. Paul plainly calls it a gift... 'For unto you it is given in behalf of Christ, not only to believe in Him, but also to suffer for His sake' (Phil. 1:29).
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 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.
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.
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.
Let us love silence till the world is made to die in our hearts. Let us always remember death, and in this thought draw near to God in our heart--and the pleasures of this world will have our scorn.
A small affliction borne for God's sake is better [before God] than a great work performed without tribulation, because affliction willingly borne brings to light the proof of love.
It is impossible for the soul to be liberated from turbulent thoughts without the virtue of non-possessiveness. And without peace of the bodily senses it is impossible for the soul to have a peaceful intellect. And if it does not come into temptations it will not acquire wisdom of the Holy Spirit. And without laborious and persistence in reading, it will not come to the discernment of thoughts. And without the stillness of thoughts, the intellect cannot move to seek the hidden mysteries of God.
The key to Divine gifts is given to the heart by love of neighbor, and, in proportion to the heart's freedom from the bonds of the flesh, the door of knowledge begins to open before it.
