“An angel of God never has wings. Some will say that they have seen a spirit; that he offered them his hand, but they did not touch it. This is a lie. First, it is contrary to the plan of God; a spirit cannot come but in glory; an angel has flesh and bones; we see not their glory. The devil may appear as an angel of light. Ask God to reveal it; if it be of the devil, he will flee from you; if of God, He will manifest Himself, or make it manifest.”
