Love 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 NinevehJust as a strongly flowing fountain is not blocked up by a handful of earth, so the compassion of the Creator is not overcome by the wickedness of his creatures.
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 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 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 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.
