The Bible says:  "For the living know that they shall die:  but the dead know not any thing, neither have they any more reward; for the memory of them is forgotten."  Ecclesiastes 9:5.  Evil angels will come to us in the form of dead loved ones...  To deceive if possible the very elect:  "And no marvel; for Satan himself is transformed into an angel of light."  2 Corinthians 11:14.  Beware.
