Having the peace of God is not enough

Question: "Suppose you have the peace of God. Will not that quiet you?"
Answer: "No, I must have the God of peace; as the peace of God, so the God of peace; that is, I must enjoy that God that gives me the peace; I must have the Cause as well as the effect; I must see from whence my peace comes and enjoy the Fountain of my peace, as well as the streams of my peace."
