Not only should we observe moderation with food, but we must also abstain from every other sin so that just as we fast with our stomach, we should fast with our tongue. Likewise, we should fast with our eyes; i.e. not look at agitating things, not allow your eyes freedom to roam, not to look shamelessly and without fear. Similarly, arms and legs should be restrained from doing any evil acts.
Dorotheus of GazaNo one who lies is linked to God. God is the truth. He says, 'I am the Way, the Truth and the Life' (Jn. 14:6). See how we sort ourselves out and what position we take up through lying ? clearly on the side of the evil one. If, therefore, we want to be saved, we must with all our hearts love the Truth and guard ourselves from every kind of falsehood so that we may not be separated from truth and from life.
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 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 GazaA 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 GazaHe answered, "The woman whom You gave to be with me" (Gen 3:9-12), he did not say, "the woman deceived me," but "The woman whom You gave to me," as if he wanted to say: "This catastrophe has come upon me because of You." So it is, brethren, since Man is not accustomed to blame himself. He does not hesitate to consider even God as the cause of evil.
