Hypnotism is the inducement of a sleeplike state during which an individual remains responsive to outside suggestion. In other words, a person under hypnosis temporarily loses full control over his thought processes and his actions.
Christians should never to be involved in any such practices! The Bible says, “Gird up the loins of your mind” (I Pet. 1:13). We are to control our EVERY THOUGHT so that it is in obedience to
Jesus Christ (see II Corinthians 10:5). This would be impossible to do in a trancelike condition during which one’s mind can be manipulated by outside suggestion.
Rather than purposely allowing our minds to become blank and giving control to others, we are told to fill our minds with those things that are true, honest, pure, lovely, and of good report (see Philippians 4:8). God gives His people the spirit of a sound mind (II Tim. 1:7).
