He who has been granted the gift of knowledge and yet nurses bitterness, rancor or hatred towards another is like one who pricks his eyes with thorns and thistles. Thus knowledge of necessity has need of love.
Love, by its nature, is a resemblance to God, insofar as this is humanly possible. In its activity it is inebriation of the soul. Its distinctive character is to be a fountain of faith, an abyss of patience, a sea of humility.
He who has been granted the grace of spiritual knowledge and yet harbors resentment, rancour or hatred for anybody, is like someone who lacerates his eyes with thorns and thistles. Hence knowledge must be accompanied by love.
Observe your thoughts, and beware of what you have in your heart and your spirit, knowing that the demons put ideas into you so as to corrupt your soul by making it think of that which is not right, in order to turn your spirit from the consideration of your sins and of God.
Let us consider one another, but not so as to cause rivalry between one another, but provoking one another unto charity. What is the meaning of, to provoke unto charity? Unto loving each other more and more.
Let us avail ourselves of the example of that holy staretz who used to say: 'Depart, evil one; come, beloved!' Once a brother who overheard his words and supposed that the staretz was speaking to another man asked him 'With whom are you conversing, father?' And the staretz answered: 'I am driving away evil thoughts and calling the good ones to my side.' And so, if we are tempted, let us use the words of that staretz, or others like them.
The man who has found love eats and drinks Christ every day and hour and so is made immortal. 'Whoever eats of this bread', He says, 'which I will give him, will never taste death.' Blessed is he who consumes the bread of love, which is Jesus! He who eats of love eats Christ, the God over all, as John bears witness, saying, 'God is love.'
When you intend to do something and see that your thought is perturbed, and if after invoking God's Name it remains perturbed even by a hair's breadth, know from this that the action you mean to commit is from the evil one and refrain from commiting it. For nothing done with perturbation is pleasing to 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.
Love does not reflect. Love is simple. Love never mistakes. Likewise believe and trust without refection, for faith and trust are also simple; or better: God, in Whom we believe and in Whom we trust, is an incomplex Being, as He is also simply love.
