If a man has some spiritual gift and feels compassion for those who do not have it, he preserves the gift because of his compassion. But a boastful man will lose it through succumbing to the temptations of boastfulness.
Those who have sinned must not despair. Let that never be. For we are condemned not for the multitude of evils, but because we do not want to repent...
When tested by some trial you should try to find out not why or through whom it came, but only how to endure it gratefully, without distress or rancor.
He who wants to cross the spiritual sea is long-suffering, humble, vigilant and self-controlled. If he impetuously embarks on it without these four virtues, he agitates his heart, but cannot cross.
Hence, in whatever state a person is, he sometimes finds himself making pure and intense prayers. For even from that first and lowest sort, which has to do with recalling the future judgment, the one who is still subject to the punishment of terror and the fear of judgment is occasionally so struck with compunction that he is filled with no less joy of spirit from the richness of his supplication than the one who, examining the kindnesses of God and going over them in the purity of his heart, dissolves into unspeakable gladness and delight. For, according to the words of the Lord, the one who realizes that more has been forgiven him begins to love more.
Temptations are sent for improvement when God delivers his righteous ones to various temptations, humiliating them for some slight and unimportant offense, or to increase their purity, in order that every uncleanliness of thought, or... dross which He sees they have harbored in secret, may be burnt away in this present life, and that so He may bring them, as it were pure gold, to the future judgment...
It is impossible for the mind to escape disturbing thoughts, but it is possible, for any who take sufficient care, either to admit them or reject them.
Sometimes, when we are overcome by pride or impatience and are unwilling to amend our ill-conditioned and disordered way of life, we complain that what we need is solitude, as though in solitude, meeting with no provocation, we should find there the virtue of patience, making excuses for our slackness, and laying the blame of our agitation not upon our own lack of patience, but ascribing it to the faults of our brethren, whereas so long as we impute to others the causes of our own faults, we shall never be able to reach the goal of patience and of perfection.
Blessed are the pure in heart, for they shall see God. Everything we do, our every objective, must be undertaken for the sake of this purity of heart. This is why we take on loneliness, fasting, vigils, work, nakedness. For this we must practice the reading of the Scripture, together with all the other virtuous activities, and we do so to trap and to hold our hearts free of the harm of every dangerous passion and in order to rise step by step to the high point of love.
