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 GazaTherefore, we know about God that He loves and shows pity on His creatures, and also that He is the source of wisdom and knows how to govern everything concerning us. Nothing is impossible for Him, but everything is subject to His will. We must also realize that everything He does is for our benefit and we must accept it with thankfulness...as from a benefactor and a good lord even if is troublesome. For everything is done with right judgment, and God, Who is merciful, does not overlook even the smallest sadness that we suffer.
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
