No one can sense his own weakness is at least a small temptation is not allowed to afflict either his body or his soul. Then, comparing his weakness to the help of God, a man comes to know its magnitude. But whoever does not know that he needs God's help, let him make many prayers. Insofar as he multiplies them, in that measure will he be humbled.
Isaac of NinevehIt is impossible to draw near to God without sorrows, without which human righteousness cannot remain unchanged... If you desire virtue, than give yourself to every affliction, for afflictions produce humility. If someone abides in virtue without afflictions, the door of pride is opened to him.
Isaac of NinevehThe soul that loves God has its rest in God and in God alone. In all the paths that men walk in in the world, they do not attain peace until they draw nigh to hope in God.
Isaac of NinevehIf, at the time when the mind is praying it is distracted by any extraneous thought or worry about anything, then this prayer is not called pure.
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.
