I ask this because I've read an exceptionally powerful visionary dream where the Patriarch Adam, Abel, Lot and Jonah give a gifted Christian a powerful series of messages that sure are needed at this time. I do believe that it is entirely different for the deceased to speak to somebody in a dream or vision than if they conjured the dead in some sort of a seance. Rick Joyner, The Call: We also need to have hope for the future and not be deceived into thinking that the earth will be destroyed in a nuclear war. https://www.near-death.com/experiences/exceptional/howard-storm.html#a04 You can also listen to this book if you choose: The message from Adam is just after 1:07:22
Deuteronomy 18:10 "There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch, Or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer. For all that do these things are an abomination unto the LORD: and because of these abominations the LORD thy God doth drive them out from before thee." I believe that the vision of Moses and Elijah that was given to Messiah Yeshua - Jesus and three of his disciples is also a totally different type of thing than a seance. https://www.blueletterbible.org/nkjv/mat/17/4/s_946004
