The Son of God speaks: "When there is a fire in the house, it is necessary to have a venthole through which the smoke can go out so that the inhabitant may enjoy the warmth. Thus, for everyone who desires to keep my Spirit and my divine grace, frequent confession is useful so that through it, the smoke of sin may escape. For although my divine Spirit is in itself unchangeable, nevertheless it quickly withdraws from the heart that is not guarded by humble confession."
