Accordingly if the devil should say, 'Do not drink,' you should reply to him, 'On this very account, because you forbid it, I shall drink, and what is more, I shall drink a generous amount. Thus one must always do the opposite of that which Satan prohibits. What do you think is my reason for drinking wine undiluted, talking freely, and eating more often, if it is not to torment and vex the devil who made up his mind to torment and vex me.
Even like as St. Paul was converted, just so are all others converted; for we all resist God, but the Holy Ghost draws the will of mankind, when he pleases, through preaching.
In Romans 7, St. Paul says, "The law is spiritual." What does that mean? If the law were physical, then it could be satisfied by works, but since it is spiritual, no one can satisfy it unless everything he does springs from the depths of the heart. But no one can give such a heart except the Spirit of God, who makes the person be like the law, so that he actually conceives a heartfelt longing for the law and henceforward does everything, not through fear or coercion, but from a free heart.
