I am sure Christianity is first, last, and foremost an encounter with the supernatural, the risen Jesus Christ, although much of what passes for Christianity is merely cultural. I am also sure that much of what passes for Hinduism, Islam, etc., is also cultural. But are there also supernatural elements in these religions also? And if so, what should we think about them?
Shamanism, or tribal religion claiming to be in touch with a higher power, is commonly dismissed by some educated folks as superstition. Others think differently. Sitting Bull was the great shaman of the Sioux/Dakota tribe, and he was the Indian I most admired as a boy. Whether he did miracles or not, I do not know. Perhaps he was just a very wise person. I interviewed a very Godly minister in Sweetwater, Tn, and we spoke of spiritual matters. He mentioned a neighbor who had supernatural powers not of God. He was a shaman, in other words. When I asked him to tell me some things he did, he declined, saying he did not want to glorify Satan.
1 Samuel 28.3-25 tells us that King Saul consulted a medium/witch, who then brought up the prophet Samuel from the dead. Whatever we may think of this passage, it did Saul no good whatsoever, and brought much distress to him. Nor did the witch benefit from this trick either. In Acts 16, Luke records that a slave girl had a spirit of divination that brought much money to her owners. When she followed Paul yelling for many days, Paul cast out the spirit in the name of Jesus Christ. Her owners were much annoyed (because they lost money ), and lobbied until Paul and Silas were thrown in jail.
The leader of a large ( and rapidly diminishing) denomination in the USA was also much annoyed at the story, claiming that Paul took away her special gift, and did her a disservice. Actually, she was freed to follow Jesus Christ, and her greedy and evil owners were freed to make an honest living without exploiting a poor girl! Now if the leader would ever get supernaturally converted to Jesus, her cultural bias would be kaput!
So the Bible teaches that spirits exist, and people can put themselves under the influence of a higher power in different cultures. When that power is the Holy Spirit, he is subject to the prophet or other person who is in dwelt by this spirit. In other words, we do not run around barking like dogs or having manic laughter unless we are possessed by evil spirits (or just trying to entertain idiotic folks) . The only spirit I want around me is the Holy Spirit, who is the third person of the Trinity, is perfect love, and who always brings glory to Jesus Christ. As someone said, “It is not how high you jump that matters, but his straight you walk when you hit the ground.” The Holy Spirit guides us to walk straight with Jesus Christ in holiness, and to reject any spirit or logic or feeling or cultural norm that does not do that.
