When 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 GazaIf a man really sets his heart upon the will of God, God will enlighten a little child to tell that man what is His will. But if a man does not truly desire the will of God, even if he goes in search of a prophet, God will put into the heart of the prophet a reply like the deception in his own heart.
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 GazaIn the measure that we pay attention and take care to carry out what we hear, God will always enlighten us and make us understand His will.
Dorotheus of GazaIf you cannot be merciful, at least speak as though you are a sinner. If you are not a peacemaker, at least do not be a troublemaker. If you cannot be assiduous, at least in your thought be like a sluggard. If you are not victorious, do not exalt yourself over the vanquished. If you cannot close the mouth of a man who disparages his companion, at least refrain from joining him in this.- St. Isaac the Syrian
Dorotheus of Gaza
