Duet. 18: 10-12…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:
Communicating or consulting with Spirit’s outside of God Himself is the sin of necromancy. Necromancy is a claimed form of magic that involves communication with the deceased.
There are modern trends, certain movements, and various religious concepts around the globe that allow communication with the dead.
This very dangereous and mystical form of enchantment goes on around the globe in this modern era. It takes people away from the truth about man’s personal relationship with God through Christ and gives a false impression and false hope.
Communication with God is simply talking to God or making your requests known to God, prayerfully. A clean heart that comes from Christ is the element that connects man spiritually and permits communication with God.
