Do not oppose the thoughts, which the enemy sows in you, but rather cut off all converse with them by prayer to God. We have not always strength enough so to oppose hostile thoughts as to stop them; on the contrary, in such attempts they frequently inflict us with a wound that is long in healing.
A life of spiritual endeavor is the mother of sanctity; from it is born the first experience of perception of the mysteries of Christ--which is called the first stage of spiritual knowledge.
The Lord’s most important commandments are 'Judge not, and ye shall not be judged; condemn not, and ye shall not be condemned; forgive, and ye shall be forgiven.' Moreover, those desirous of salvation should always keep in mind the words of St. Peter Damascene, that creation takes place between fear and hope.
You know that evil entered into us through the transgression of the commandments. Hence it is obvious that by keeping them, evil departs from us. But without the doing of the commandments we should not even aspire or hope for purity of soul, because at the very outset we do not walk on the path that leads us to purity of soul. Do not say that God can give us the grace of purity of soul even without our keeping the commandments.
A brother asked Abba Isidore the priest, 'Why are the demons so frightened of you?' The old man said to him, 'Because, ever since the day I began practicing ascesis, I have striven to prevent anger from reaching my lips.'
A holy elder, seeing with his own eyes a certain brother fall into deep sin, not only did not judge him, but wept and said: 'He fell today; without doubt I will fall tomorrow. But he certainly will repent, whereas for myself, I am not so sure of this.'
When the holy Abba Anthony lived in the desert he was beset by boredom, and attacked by many sinful thoughts. He said to God, 'Lord, I want to be saved but these thoughts do not leave me alone; what shall I do in my affliction? How can I be saved?' A short while afterwards, when he got up to go out, Anthony saw a man like himself sitting at his work, getting up from his work to pray, then sitting down and plaiting a rope, then getting up again to pray. It was an angel of the Lord sent to correct and reassure him: 'Do this and you will be saved.' At these words, Anthony was filled with joy and courage. He did this, and he was saved.
Fasting is the champion of every virtue, the beginning of the struggle, the crown of the abstinent, the beauty of virginity and sanctity, the resplendence of chastity, the commencement of the path of Christianity, the mother of prayer, the well-spring of sobriety and prudence, the teacher of stillness, and the precursor of all good works. Just as the enjoyment of light is coupled with healthy eyes, so desire for prayer accompanies fasting that is practiced with discernment.
'Grace always precedes temptations.' He knew that grace always precedes temptations as a forewarning preparation. As soon as you perceive grace, gird yourself and say: 'Here comes the call to battle! Beware, attend, O Clay, to where the wicked on will strike the battle. Many times it comes quickly, and many times after two or three days. In any event, it will come, and the earthworks must be firm. Confessions every evening, Obedience to the elder, humility and love towards all. By these means lighten the affliction.' Grace is divided into three stages: purifying, enlightening, and perfecting. So also are deeds: natural, supernatural, contranatural. According to these three stages on ascends and descends. The great gifts one receives are also three: contemplation, love, dispassion.
