Dowsing is a practice employing divinatory implements and methods in order to search out information, such as a site of water, or the nature or location of disease and its proper treatment. Dowsing claims to work through a practitioner's natural sensitivity to nature's geomagnetic phenomena. The influence of dowsing is greater than most people realize and it is even used in the church. People may think that dowsing is harmless but the real dangers in this practice are exposed and a biblical evaluation is shown by the authors.
