I hope that places you comfy, particularly since you aren’t even utilizing them for divination.
Technically goat intestines, bone/cola nut/coin/and so forth. tossing, sticky/slippery disk rubbing, pendula, cube, dousing rods and plenty of others that derive sequential “sure/no” values are additionally completely different media of the identical “lot drawing” idea. Gazing (water, mirror, oculus, crystals), Guiding (Ouija planchette, dousing, pendulum), and Channeling (opening to obtained information through clair-audience/voyance/utterance/sentience) are those which can be forbidden because of considerations of possession throughout opening. You’re almost definitely not doing something not-biblical, to those that truly perceive the phrases within the textual content. 
Many church buildings do get overzealous, so do not be stunned once they persist though they’re in translation err.
Prophesy is technically not dangerous divination per se. Neither is dream deciphering. These are seen because the divine intentionally speaking to the human, not the human risking opening as much as attain the divine. The latter is perceived as exposing one human to “the astral” unguided and unprotected, which may find yourself with a ‘cellphone name’ answered by anybody in between, who could have sick intent. Hope that helps!
(Sure, there have been USA Christian communities who forbade D&D due to the cube, however allowed its early lot drawing of chits. No, do not ask me to sq. that spherical peg. Simply settle for that some persons are persnickety in literal interpretation.
