Hypnotism results in an altered state of consciousness where the mind becomes susceptible to outside influence and is less able to tell what is real and what is not. For example, the mind can refuse to acknowledge the reality of pain in the body. It also leaves the mind – the gateway to our spirit – open to far more dangerous and subtle influences, which can bring us into the realm of the occult. The Bible warns strongly against “charmers and enchanters” Deut 18:10-12. The Old Testament heathen practice of what has recently become acceptable in medicine and psychiatry as hypnosis.
The Word is clear on this. We are to love the Lord out God “With all of your heart, with all your soul, and with all your mind.” Matt 22:37 God has given us a “sound mind” 2 Tim 1:7 and we should not lose control of any part of it at any time. Our minds must be set on things “above” Col 3:1-2, fully concentrated on the Lord (Isaiah 26:3). sober (to be in your right mind – Titus 2:6) and fully committed to and open to His suggestions.
The potential dangers of this practice are such, that the Christian would be well advised to steer clear of it!
