Just as our Lord is solicitous about our salvation, so too the murderer of men, the devil, strives to lead a man into despair... Judas the betrayer was fainthearted and unskilled in battle, and so the enemy, seeing his despair, attacked him and forced him to hang himself; but Peter, a firm rock, when he fell into great sin, like one skilled in battle did not despair nor lose heart, but shed bitter tears from a burning heart, and the enemy, seeing these tears, his eyes scorched as by fire, fled far from him wailing in pain.
The evil one cannot comprehend the joy we receive from the spiritual life; for this reason he is jealous of us, he envies us and sets traps for us, and we become grieved and fall. We must struggle, because without struggles we do not obtain virtues.
Leave off all evasions, bend your neck to humility and obedience, and you will receive mercy. If you practice with humility and obedience what you hear from the fathers, God will grant you His blessed help not only in the work you are doing, but will make all your works successful, for He protects the path of those who fear Him and watches their progress.
When the enemy tempts you with thoughts of faithlessness, with all your heart say, I believe completely whatever the Church believes, whatever Christ says in the Holy Gospels, whatever the Holy Apostles and the Holy Fathers said. 'I don't, however, believe you, devil, for you are a liar and a thief.'
For as merchants on a voyage, though they find a wind to suit them and the sea calm, but have not yet reached the haven, are always subject to fear, lest suddenly a contrary wind should stir and the sea rise into billows, and the ship be in peril, so Christians, even if they have in themselves a favorable wind of the Holy Spirit blowing, are nevertheless yet subject to fear, lest the wind of the adverse power should rise and blow on them, and stir disturbance and billows for their souls. There is need therefore of great diligence, that we may arrive at the haven of rest, at the perfect world, at the eternal life and pleasure, at the city of the saints, at the heavenly Jerusalem, at the church of the firstborn (Heb. xii. 23.). Unless a man gets through these measures, he is under much fear, lest in the meantime the evil power should effect some fall.
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.
No matter what misfortune might befall you, no matter what unpleasantness might occur, say 'I will endure this for Jesus Christ's sake!' Just say that, and you will feel better, for the Name of Jesus Christ is powerful. Before It, all difficulties abate, and demons disappear. Your annoyance and faintness of heart will abate when you repeat His most sweet Name. Lord, grant unto me to see my transgressions. Lord, grant unto me patience, magnanimity, and meekness.
Wherever we are and whatever our circumstances, the enemy always tries to prevent us from actively responding to the call. Pray for help. For help that you may never fail to respond. And beware lest, having received help and having done the right deed because of it, you should grow proud and acquire the habit of condemning others, in the secret chambers of your heart. Beware! For this would make all the fruits of your good works wither.
Most men not only bear Satan's burden willingly in their hearts, but they become so accustomed to it that they often do not feel it, and even imperceptibly increase it. Sometimes, however, the evil enemy increases his burden tenfold, and then they become terribly despondent and fainthearted, they murmur and blaspheme God's name. The usual means that men... take to drive away their anguish are... entertainments... But such means afterwards increase still more the anguish and weariness of their hearts. If, happily, they turn to God, then the burden is removed from their heart, and they clearly see that previously the heaviest burden was lying on their heart, though frequently they did not feel it.
Often when someone throws a rock at a dog, rather than rushing at the person who threw the stone, the dog will run and bite the stone. We do the same thing. The tempter uses someone else to tempt us, either in word or deed, and, rather than deal with the tempter who threw the stone, we bite the rock, our fellow man that the hater of the good used against us.
The enemy constantly endeavors to awaken in the abyss of the human heart a great turmoil about trifles. This is one of his tricks to blind our soul to the sun of truth, Christ our Lord, hidden in the heart's core of every one of our neighbors.
Beware of the counsels of the evil one, if he should come in the guise of one professing truth to beguile you and lead you into deceit. Even if he should come to you as an angel of light, do not believe him or obey him: for he is apt to fascinate the faithful by the attractive semblance of truth.
And the opinion, extremely popular in our times, that 'it's all the same which church you go to; after all, God is one' is in agreement with this tendency. Yes! God is one, but, you know, He also gave us one faith; He created one Church for us, not many different faiths and 'churches.' This is confirmed by the holy Apostle Paul when he says, 'One Lord, one faith, one baptism, one God and Father of all,' and so we Christians should form 'one body and one spirit,' as we are called to 'in one hope of our calling' (Eph. 4:4-6). If there is only one true faith and only one true Church, then as a consequence all other faiths and 'churches' are false, not true. How then can anyone say that all faiths and 'churches' are of equal value and that 'it is all the same which church you go to.' Therefore one can and must speak not of the ecumenical unification of everyone for the creation of some new Church, but only of the restoration of union between all who have fallen away and the one true Church of Christ to which Christ the Savior Himself gave the great and sure promise that 'the gates of hell will not prevail against it' (Matt. 16:18).
'Behold, Satan hath desired to have you, that he may sift you as wheat' (Lk. 22:31). It is he who so greatly distracts our thoughts in the temple during Divine Service and at home during prayer; it is he who draws away your thoughts from God, from our souls and the souls of others, from heavenly and eternal things; it is he who occupies us with early trifles or with earthly vanity, with earthly nothingness, with earthly allurements, with food, drink, dress, houses, etc. We must pray for each other that our faith should not fail as the Savior prayed for Peter.
