When spirits are in this second state, they actually look exactly the way they were inwardly in the world. The things they had done and said in secret are made public, too, because now, since outward factors are not restraining them, they say the same things openly; and they keep trying to do the same things without any of the fear for the reputations that they had in the world. Further, they are then led into many states of their evils, so that they look to angels and good spirits like the people they really are.
This is how hidden things are opened and covert things are uncovered according to the Lord’s words, “Nothing is hidden that will not be disclosed or concealed that will not be recognized. What you have said in darkness will be heard in the light, and what you have spoken in the ear in closets will be proclaimed on the rooftops” (Luke 12:2–3); and again, “I tell you, every idle word people have spoken, they will give an account of it on the day of judgment” (Matthew 12:36).
