Be dead in life, and you will not live in death. Let your soul die strenuously, and not live in weakness. Not only those who suffer death for the sake of faith in Christ are martyrs; but also those who die because of their observance of His commandments.
Isaac of NinevehIf a man does not argue with the thoughts that the enemy secretly sows in us, but by prayer to God uproots conversation with them, this is a sign that his mind has attained wisdom, and that he has found a short path.
Isaac of NinevehSpeech is the organ of this present world. Silence is the mystery of the world to come.
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 NinevehNo 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 NinevehWithout temptations, it is not possible to learn the wisdom of the Spirit. It is not possible that Divine love be strengthened in your soul. Before temptations, a man prays to God as a stranger. When temptations are allowed to come by the love of God, and he does not give in to them, then he stands before God as a sincere friend. For in fulfilling the will of God, he has made war on the enemy of God and conquered him.
