The Lord bears all the weaknesses of men, but He does not bear a man who is always murmuring, and does not leave Him without chastisement.
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 NinevehA man who is truly humble is not troubled when he is wronged and he says nothing to justify himself against the injustice, but he accepts slander as truth; he does not attempt to persuade men that he is calumniated, but he begs forgiveness.
Isaac of NinevehThe prayer of one who does not consider himself a sinner is not accepted by the Lord.
Isaac of NinevehWhoever hates his sins will stop sinning; and whoever confesses them will receive remission. A man can not abandon the habit of sin if he does not first gain enmity toward sin, nor can he receive remission of sin without confession of sin. For the confession of sin is the cause of true humility.
