Superstition, psychics, and mediums are useless and those who rely upon them have no judgment. Not only that, but reliance upon them is inconsistent with a reliance upon the Holy Spirit. And so it should come as a surprise that born-again Christians are just as likely to employ the services of a psychic or a medium as non-Christians.
What do you think about superstition, psychics, and mediums and what should we do about it?
Most commercial psychics and mediums would be pure bunkum anyway. Those who really do possess abilities generally cannot control it enough to make it function efficaciously either 24/7 or on a whim or on demand. But that would be beside the point and off topic.
What about those in Christian circles who treat "the prophetic" as their own personal divine fortune cookie, or who try to discern "what the Lord says" by opening a Bible at random and sticking their finger in it without looking to pick a verse? Both these things end up being forms of divination and come from a superstitious mindset. They do not suddenly become "holy" because the language and praxis used to express this superstitious mindset happens to be "Christianese" instead of something else.
What about Christians avoiding those things not from a trust in Christ and an awareness of the truth but rather from a superstitious fear? Does that make avoiding those things holy, to do so not because one trusts God for all things but because one fears the devil, or fears spiritual contamination? Think about it. Some have the attitude of "whatever works" -- but scripture seems pretty clear that a spirit of fear does not come from God, but rather power, love, a sound mind -- a rational and calm basis for decisions, not a fearful reactionary one. Should we NOT be concerned if the basis of our decisions, even seemingly "right" ones, has come from the wrong spirit? Hmmmm.
Exercises in discernment for Christians would be, IMO, much better and effectively employed in discerning things liable to trip up Christians -- not things they would be avoiding anyway. For example, most Christians don't need to spend hours discussing why they would avoid performing black magick rituals ... but most Christians have no clue that every time they push their judgment of someone as the truth about that person, or every time they wag their little tongues in covert operations of social engineering, consensus-perception deck-stacking, etc., especially in combination with spiritual pride (crusade zeal), they have, like it or not, engaged in a low-level version of black magick. Now that would be something they ought to spend time sorting out.
