I am a Christian, you say, and content yourself with this. This is the first deceit - transferring to yourself the privileges and promise of Christianity, without any care to root true Christianity into yourself; or to ascribe to yourself that which can only be acquired by your strength and inner worthiness. Explain to yourself that it is illusory to hope in a name, that God can raise a son of Abraham from a stone and can take away your promise at any time if the conditions for participating in them are not soon fulfilled. Mainly, clarify to yourself what it means to be a Christian, unite yourself to this ideal, and you will see just how stable is this buttress to your blindness.
It is not possible for any man to draw near to Christ without tribulation, and without afflictions his righteousness cannot be preserved unchanged. If he puts an end to the labors that make righteousness increase, he will put an end to that which guards it, and his righteousness will be like unguarded treasure. And he will be like a gladiator surrounded by enemy ranks and stripped of his weapons, like a ship bereft of its sails and tackle, and like a garden deprived of its source of water.
If you believe in a Divine Providence which determines the earthly fate of everyone and the way by which he is to be saved, you must also believe that the disposition of your life is the most suitable for you in working out your salvation.
A haughty person is not aware of his faults, or a humble person of his good qualities. An evil ignorance blinds the first, an ignorance pleasing to God blinds the second.
If you pile up on one side of the scales all the works demanded by ascetic life, and on the other side-silence, you will find that the latter outweighs the former. Many good counsels have been given us, but if a man embraces silence, to follow them will become superfluous.
Hold faith and humility fast within you; for through them you will find mercy, help, and words spoken by God in the heart, along with a protector who stands beside you both secretly and manifestly.
Faith is the sincere confession that God, Who is worshipped in the Trinity, Who created all things and provides for all, saves us who are fallen, through the power of the death on the Cross of the incarnate Son of God, by the grace of the Most Holy Spirit in His Holy Church. The beginnings of renewal, which are established in this life, will appear in all their glory in the future age, in a way that the mind cannot comprehend nor the tongue express.
We must not think that anyone slips and comes to ruin by a sudden fall; it is rather that he has been deceived by the beginnings of evil habits, or else, by prolonged mental negligence, virtue has little by little withdrawn from him, and vices have thereby grown stronger, and he has come thus to a miserable fall. For Pride goeth before destruction, and the spirit is lifted up before a fall (Prov.16:18 LXX). Just as a house never falls in ruin by a sudden shock unless there has been some long-standing fault in the foundations, or by the prolonged carelessness of the tenants, little driblets at first penetrate through and slowly undermine the walls, which, inconsequence of the old neglect, open in ever wider apertures and crumble away, and then let in the tempest of rain and storm in torrents. For by slothfulness a building shall be brought down, and through the weakness of hands the house shall drop through (Ecclus. 10:19 LXX).
Just as we must beware of overeating, so too we must beware of excessive temperance or abstinence. Excessive temperance weakens the body, destroys wakefulness, coolness and freshness which are indispensable for vigilance, and which fade and weaken when the physical powers succumb and fail. If you force a weak body to labor beyond its powers, you subject your soul to double darkness, and lead it into confusion (and not relief)...
He who knows himself pays no heed to the sins of others, but looks at his own and is always repenting over them; he reflects concerning himself, and condemns himself, and does not interfere in anything apart from his own position.
