To wage war only with the sins that make their appearance as actual deeds would be just as unsuccessful as cutting down weeds in a garden instead of digging them up at the root and throwing them out. Sins appear as inevitable outgrowths from their roots, the passions of the soul.
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.
If we cut off the causes of the passions for only a short while, and occupy ourselves with spiritual contemplation without making it our sole and constant concern, we easily revert to the passions of the flesh, gaining nothing from our labor but theoretical knowledge coupled with conceit. The result is a gradual darkening of this knowledge itself and a complete turning of the intellect towards material things.
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.
Charity, temperance, contemplation, and prayer please God; gluttony, licentiousness, and what multiplies them, please the flesh. Therefore they who are in the flesh cannot please God. And they that are Christ’s have crucified their flesh with the passions and concupiscences.
Nothing is more unsettling than talkativeness and more pernicious than an unbridled tongue, disruptive as it is of the soul’s proper state. For the soul’s chatter destroys what we build each day and scatters what we have laboriously gathered together.
When the intellect begins to advance in love for God, the demon of blasphemy starts to tempt it, suggesting thoughts such as no man but only the devil...could invent. He does this out of envy, so that the man of God, in his despair at thinking such thoughts, no longer dares to soar up to God in his accustomed prayer. But the demon does not further his own ends by this means. On the contrary, he makes us more steadfast. For through his attacks and our retaliation we grow more experienced and genuine in our love for God.
Just as the human word which proceeds naturally from the mind is messenger of the secret movements of the mind, so does the Word of God, who knows the father by essence as Word knows the Mind which has begotten it (since no created being can approach the Father without Him), reveal the Father whom He knows. As the Word of God by nature, He is spoken of as the 'messenger of the great plan of God'.
Do not measure yourself by the standard of weaker men, but strive rather to apply yourself to the commandment of love. In measuring yourself by the former you fall into the pit of presumption, in striving for the latter you advance to the heights of humility.
If in time of trial a man does not patiently endure his affliction, but cuts himself off from the love of his spiritual brethren, he does not yet possess perfect love or a deep knowledge of divine providence.
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.
Do we forgive our neighbors their trespasses? God also forgives us in His mercy. Do we refuse to forgive? God, too, will refuse to forgive us. As we treat our neighbors, so also does God treat us. The forgiveness, then, of your sins or unforgiveness, and hence also your salvation or destruction, depend on you yourself, man. For without forgiveness of sins there is no salvation. You can see for yourself how terrible it is.
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.
Almsgiving heals the soul's incensive power; fasting withers sensual desire; prayer purifies the intellect and prepares it for contemplation of created beings. For the Lord has given us commandments which correspond to the powers of the soul.
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.
