When the intellect is pure, sometimes God Himself approaches and teaches it; and sometimes the angelic powers, or the nature of the created things that it contemplates, suggests holy things to it.
There are three things that move us to the good: natural tendencies, the holy Powers, good choice. The natural tendencies - as, for instance, when what we wish men would do for us, we likewise do for them; or, when we see someone in sore straits, we then naturally have pity. The holy Powers - as when moved to some fine deed, we experience their good assistance and prosper. Good choice - when, for example, discerning good from evil, we choose the good.
Patience reigns quietly and fruitfully in the life of the man who does not harm or endanger anyone, who is content with little and is obedient to the commandments of the Heavenly Father.
Suffering cleanses the soul infected with the filth of sensual pleasure and detaches it completely from material things by showing it the penalty incurred as a result of its affection for them. This is why God in His justice allows the devil to afflict men with torments.
The outcome of every affliction endured for the sake of virtue is joy, of every labor rest, and of every shameful treatment glory; in short, the outcome of all sufferings for the sake of virtue is to be with God, to remain with Him for ever and to enjoy eternal rest.
Someone may say: 'I have faith, and faith suffices for salvation.' St. James gives him the answer: 'Even the demons believe, and shudder. Faith without works is dead.' (James 2:17-19)
Even a pious person is not immune to spiritual sickness if he does not have a wise guide -- either a living person or a spiritual writer. This sickness is called prelest, or spiritual delusion, imagining oneself to be near to God and to the realm of the divine and supernatural. Even zealous ascetics in monasteries are sometimes subject to this delusion, but of course, laymen who are zealous in external struggles (podvigi) undergo it much more frequently. Surpassing their acquaintances in struggles of prayer and fasting, they imagine that they are seers of divine visions, or at least of dreams inspired by grace. In every event of their lives, they see special intentional directions from God or their guardian angel. And then they start imagining that they are God's elect, and often try to foretell the future. The Holy Fathers armed themselves against nothing so fiercely as against this sickness -- prelest.
If you have received from God the gift of knowledge, however limited, beware of neglecting charity and temperance. They are virtues which radically purify the soul from passions and so open the way of knowledge continually.
All Christians, clergy, laity and monks, when rising from sleep must first think of and remember Christ. They must offer this remembrance to Christ as a sacrifice and first-fruits of every thought (Hebrews 13:15). For we must remember, before every thought, Christ Who saved us and has loved us so greatly, for we are, and are called, 'Christians'. We put him on by divine Baptism (Gal. 3:27), and we were sealed with His Chrism. We have partaken, and do partake, of His holy Body and Blood. We are His members (I Cor. 12:27) and His temple (II Cor. 6:16). Him do we put on, and He dwells in us. For this reason we are obliged to love Him and remember Him always. Wherefore, let everyone devote time, according to his ability, and have a certain amount of this prayer as an obligation. And this suffices concerning this matter, for this is a sufficient amount of instruction for those who seek concerning it.
Some temptations bring men pleasure, some grief, some bodily pain. The Physician of souls by means of His judgments applies the remedy to each soul according to the cause of its passions.
A man of good sense, realizing how beneficial are the judgments of God, thankfully endures the tribulations they bring him, holding none guilty but his own sins. But a foolish man, when he sins and is punished, regards as the culprit of his ills either God or men, not discerning the wisdom of Divine Providence.
To those who do not long for it, wisdom is fear, because of the loss which they suffer through their flight from it; but in those who cleave to it, wisdom is loving desire, promoting an inner state of joyous activity. For wisdom creates fear, delivering a person from the passions by making him apprehensive of punishment; and it also produces loving desire, accustoming the intellect through the acquisition of the virtues to behold the blessings held in store for us.
Do not lend your ear to the tongue of the slanderer, nor your tongue to the ear of him who likes malicious talk, speaking or listening with enjoyment to words against one's neighbor. Cut yourself off from them, lest you fall away from love of God and find yourself exiled from eternal life.
If someone is judged worthy to receive the gift of knowledge but allows his heart to be full of bitterness or rancor or aversion to another, it is as if he had been struck in the eye by a thornbush. That is why knowledge is no good without charity.
