If you are truly merciful, then when what is yours is unjustly taken, don't be sad inside, and do not tell of our loss to your neighbor. Let a better loss, inflicted by those who insult you, be absorbed by your mercy.
Isaac of NinevehLove sinners, but hate their deeds, and do not disdain sinners for their failings, so that you yourself do not fall into the temptation in which they abide... Do not be angry at anyone and do not hate anyone, neither for their faith, nor for their shameful deeds... Do not foster hatred for the sinner, for we are all guilty... Hate his sins, and pray for him, so that you may be made like unto Christ, who had no dislike for sinners, but prayed for them.
Isaac of NinevehWhy do you increase your bonds? Take hold of your life before your light grows dark and you seek help and do not find it. This life has been given to you for repentance; do not waste it in vain pursuits.
Isaac of NinevehThe beginning of divine wisdom is clemency and gentleness, which arise from greatness of soul and the bearing of infirmities.
Isaac of NinevehWhen you want to direct someone toward the good, first put him at peace bodily and honor him with words of love. For nothing inclines such a man to shame and induces him to cast of his vice and be changed for the better as do bodily goods and honor, which he sees in you. Then, with love tell him a word or two, and do not be inflamed with anger toward him. Do not let him see any cause of enmity toward you. For love does not know how to lose its temper.
