Do not condemn today as base and wicked the man whom yesterday you praised as good and virtuous, changing love to hatred, because he has criticized you, but even though you are still full of resentment, commend him as before, and you will soon recover your same saving love.
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.
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.
Unless curbed by the fear of God that accompanies the practice of the virtues, spiritual knowledge leads to vanity; for it encourages the person puffed up by it to regard as his own what has merely been lent to him, and to use his borrowed intelligence to win praise for himself. But when his practice of the virtues increases concomitantly with his longing for God, and he does not arrogate to himself more spiritual knowledge than is needed for the task in hand, then he is made humble, reduced to himself by principles which are beyond his capacity.
It is no small struggle to be freed from self-esteem. Such freedom is to be attained by the inner practice of the virtues and by more frequent prayer; and the sign that you have attained it is that you no longer harbor rancor against anybody who abuses or has abused you.
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.
Restrain the excitable power of your soul by love; mortify the desiring power by self-mastery; give wings to the thinking power by prayer, and the light of your mind will never be dimmed.
Trials are sent to some so as to take away past sins, to others so as to eradicate sins now being committed, and to yet others so as to forestall sins which may be committed in the future. These are distinct from the trials that arise in order to test men in the way Job was tested.
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.
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.
The one who engages in a pursuit of wisdom out of devotion and stands prepared against the invisible forces should pray that both the natural discernment (with its proportionate light) and the illuminating grace of the Spirit remain with him. The former trains the flesh in the acquisition of virtue through asceticism while the latter illuminates the mind to select the companionship of wisdom before all others, according to the Scripture, 'He works the destruction of the strongholds of evil & of every pretension which raises itself up against the knowledge of God' (2 Cor. 10:5).
