Some people are drawn to crystals for healing. It is described as benevolent or white magic which sounds good and there is power in it. However, God wants us to wholly turn to Him for His comfort and strength when you need healing. Through His prophet Ezekiel He warns of entrapment when you rely on pagan magic (Ezekiel 13:17-21). Moses and his brother Aaron proved God's power as being stronger than the Egyptian sorcerers (Exodus 7:10-12). Apostle Paul warns us in his Second Letter to the Thessalonians (2:9-10) that Satan "will use all sorts of displays of power through signs and wonders that serve the lie". Apostle John describes in Revelations (16:13-14) how the world will get deceived by 3 evil spirits that look like frogs which perform miraculous signs. Let's stick close to God and His power to avoid being deceived. Remember Jesus warned His disciples on earth that "there shall arise false Christs and false prophets and shall show great signs and wonders insomuch that, if it were possible, they shall deceive the very elect". Be very careful.
