“For rebellion is as the sin of witchcraft,…..” 1 Samuel 15:23
The sin of witchcraft is compared to rebellion against God because rebellion against God spiritually opens you up to receive deception and lead others astray.
Manipulative, forceful and a controlling spirit often illustrates the characteristics of such an individual.
For example: God said, do not consult with familiar spirits. Don’t consult with the dead of who you once knew.
Why?
The dead are dead. The dead have completely cease from existence, where there’s no life in them. They are not conscious. Nor are they asleep.
Ecclesiastes 9:5-6
It’s actually, demons masquerading as familiar people or familiar people, spiritually coming to you to deceive you.
Therefore, the act of consulting familiar spirits is in rebellion against God, leading to spiritual deception. And inevitably using it to mislead others.
