If 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 GazaBy keeping the Commandments the soul is purified and the mind too is enlightened, and starts to function as nature intended it to. 'The command of the Lord gives light and enlightens the eyes' (Ps. 19:8).
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 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 GazaSelf-indulgence takes many forms. A man may be self-indulgent in speech, in touch, in sight. From self-indulgence a man comes to idle speech and worldly talk, to buffoonery and cracking indecent jokes. There is self-indulgence in touching without necessity, making mocking signs with the hands, pushing for a place, snatching up something for oneself, approaching someone else shamelessly. All these things come from not having the fear of God in the soul and from these a man comes little by little to perfect contempt.
