The watchful sobriety helps man more than the external works. How someone could really dominate the bodily desires - release, anger, gluttony - and not to acquire the sweetness? If it is exercised with discretion, the posting of all, the refusal of the body comfort and the opinions of others follow; if for God's sake, someone welcomes diligently and joy that makes him evil, he is pure in his heart (Mt 5,8). And if he does not despise anyone, it really is free. Do fed not hate the sinner, because we are all guilty. If, for the love of God, you blame, cry over him. Why do you hate him? These are sins that need to hate, while praying for him, if you want to be like Christ: far from being indignant against sinners, he prayed for them (Le 23:34). You who are only a man, why despise the sinner? Is it because he lacks your virtue? But where is your virtue if you lack of charity?
