For the Lord operates by means of the Internal man upon the External; and, because there is evil residing in the External, a conflict takes place. For, to the External man, which is called the flesh, spirits from hell are admitted, who are called the devil, and the Lord with the man fights against this devil, and, if the man also fights as from himself, conquers; and in so far as the devil is overcome, room is made for goods from the Internal man to enter. So, step by step, the man becomes new, and is regenerated.
