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 NinevehThe wisdom of the Holy Spirit is much greater than the wisdom of the entire world. Within the wisdom of the Holy Spirit, silence prevails; the wisdom of the world, however, goes astray into idle talk.
Isaac of NinevehBehold, for years and generations, the way of God has been leveled by the cross and by death. How is this with thee, that thou seest the afflictions of the way as if they were out of the way? Doest not thou wish to follow the steps of the saints? Or doest thou wish to go a way which is especially for thee, without suffering? the way unto God is a daily cross. No one can ascend unto heaven with comfort, we know where the way of comfort leads.

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.
