Woe is he who knowingly chooses to sin with the intention to repent when morning comes, for he knows not what the coming day or the night that precedes it will bring.
Remember, O my soul, the terrible and frightful wonder: that your Creator for your sake became Man, and deigned to suffer for the sake of your salvation. His angels tremble, the Cherubim are terrified, the Seraphim are in fear, and all the heavenly powers ceaselessly give praise; and you, unfortunate soul, remain in laziness. At least from this time forth arise and do not put off, my beloved soul, holy repentence, contrition of heart and penance for your sins.
The Lord commands all men to repent (Matt. 4:17), so that even the spiritual and those making progress should not neglect this injunction and fail to give attention to the smallest and most subtle errors.
Painstaking repentance, mourning cleansed of all impurity, and holy humility in beginners, are as different and distinct from each other as yeast and flour from bread. By open repentance the soul is broken and refined; it is brought to a certain unity, I will even say a commingling with God, by means of the water of genuine mourning. Then, kindled by the fire of the Lord, blessed humility becomes bread and is made firm without the leaven of pride. Therefore, when this holy three-fold cord or, rather, heavenly rainbow, unites into one power and activity, it acquires its own effects and properties. And whatever you name as an indication of one of them, is a token also of another. The first and paramount property of this excellent and admirable trinity is the acceptance of indignity with the greatest pleasure, when the soul receives it with outstretched hands and welcomes it as something that relieves and cauterizes diseases of the soul and great sins. The second property is the loss of all bad temper, and humility as its subsiding. The third and highest degree is a true distrust of one’s good qualities and a constant desire to learn.
True repentance consists of withdrawing from sin and nurturing hatred for it. For, lo, when someone says from his heart: I have hated deceit and been repelled by it - then God accepts him with joy.
In order not to be in daily bondage to the passions and the devil, you must set yourself an object to aim at, have this object constantly in view, and endeavor to attain it, conquering all obstacles by the name of the Lord. What is this object? The Kingdom of God, the Divine palace of glory, prepared for believers from the creation of the world. But as this object can only be attained by certain means, it also is necessary to have such means at one's disposal. And what are these means? Faith, hope, and love, especially the last. Believe, hope, and love, especially love, disregarding all obstacles; love God above everything and your neighbor as yourself. If you have not sufficient strength to preserve in your heart these inestimable treasures, fall down more often at the feet of the God of Love. Ask, and it shall be given you; seek and ye shall find; knock and it shall be opened unto you, for He Who has promised is true. Walking, sitting, lying down, conversing, or working, at every time, pray with your whole heart that faith and love may be given to you. You have not yet asked for them as you should ask - fervently and instantly - with the firm purpose of obtaining them. Say now, 'I will begin to do so henceforth.'
When Abba Agathon went down to the city to sell some of his baskets and to procure a little bread, he found near the market place an old, poor cripple. 'For the love of God, Abba,' the cripple began to plead on seeing the Saint, 'don't you, too, leave this poor wretch unaided. Bring me near to you.' Abba Agathon picked the man up and sat him next to him in the place where he had set up his baskets to sell them. 'How much money did you make, Abba?' the cripple would ask each time that the Elder sold a basket. 'Such and such,' the Elder would tell him. 'That's good enough,' the cripple finally said. 'Won't you buy me a little pie, Abba? That would be good of you, since I have not eaten since last evening.' 'With pleasure,' the Saint told him, immediately fulfilling the cripple's request. Shortly thereafter, the cripple requested some fruit. And then some sweet. Thus, for each basket that was sold, the Saint spent the proceeds, until, thanks to his patronage, all of the baskets and money were gone, without his having kept even two pennies for himself. More importantly, he did this all with great eagerness, even though he knew that he would thus go perhaps two weeks without any bread for himself. Since he had sold his last basket, the Saint got ready to leave the marketplace. 'So you're going?' the cripple asked him. 'Yes, I have completed all of my work.' 'Uh, do me the favor of taking me as far as the crossroads, and you can leave for the desert from there,' the strange old man again pleadingly said. The good Agathon took the cripple on his back and carried him to the place where he wanted to go, though with great difficulty, since he was exhausted from his day's work. As soon as he reached the crossroads and started to put down his living burden, he heard a sweet voice say to him: 'May you be blessed, Agathon, by God, both on earth and in Heaven.' The Saint raised up his eyes to see who it was who had spoken with him. The would-be old man had completely disappeared, since he was an Angel sent by God to test the Saint's love.
The vain desires of this world separate us from our homeland; love of them and habit clothe our soul as if in a hideous garment. We, traveling on the journey of this life and calling on God to help us, ought to be divesting ourselves of this hideous garment and clothing ourselves in new desires, in a new love of the age to come, and thereby to receive knowledge of how near or how far we are from our heavenly homeland. But it is not possible to do this quickly; rather one must follow the example of sick people, who, wishing the desired (health), do not leave off seeking means to cure themselves.
Lift up and stretch out your hands, not to heaven but to the poor; for if you stretch out your hands to the poor, you have reached the summit of heaven. But if you lift up your hands in prayer without sharing with the poor, it is worth nothing... Every family should have a room where Christ is welcomed in the person of the hungry and thirsty stranger. The poor are a greater temple than the sanctuary; this altar the poor, you can raise up anywhere, on any street, and offer the liturgy at any hour.
In words of boastfulness and self-justification there always lie concealed contrariness and pride, from which God turns away. After sinning one ought immediately to 'flee.' But, you will say, where? To the calm haven of heartfelt repentance. Every night before you go to sleep, tell God, the Knower of Hearts, all the sins you have committed in deed, word, and thought, and believe that God receives your heartfelt repentance. At the same time try to render your heart contrite by the memory of sudden death.
