A man who prays without ceasing, if he achieves something, knows why he achieved it, and can take no pride in it... for he cannot attribute it to his own powers, but attributes all his achievements to God, always renders thanks to him and constantly calls upon him, trembling lest he be deprived of help.
Dorotheus of GazaWhen the devil looks at a man who sincerely desires not to sin, he is not so unintelligent as to suggest to him (as he would to a hardened sinner) that he go and commit fornication or go and steal. He knows we do not want that and he does not set out to tell us something we do not want to hear; but he finds out that little bit of self-will or self-righteousness and through that, with the appearance of well doing, he will do us harm.
Dorotheus of GazaA man obtains the fear of God if he has the remembrance of his unavoidable death and of the eternal torments that await sinners; If he tests himself every evening as to how he has spent the day, and every morning as to how he has spent the night, and if is not sharp in his relations with others.
Dorotheus of GazaOh, Brethren, what is the result of pride? Oh, see what humility can do? What was the need for all these sufferings? For, if from the beginning Man had humbled himself, obeyed God, and kept the commandment he would not have fallen.
