Legalistic religion is dangerous. Here's how you can detect and avoid the poison of a religious spirit.
After Elisha watched Elijah ascend into heaven, the prophet went to the city of Jericho and performed his first miracle. The men of that city faced an environmental crisis: Their water was toxic, most likely because of the sulphur and other chemicals that had rained down upon nearby Sodom and Gomorrah years earlier. This poison had made the land barren (see 2 Kings 2:19-22) and it was probably affecting people and animals as well as plant life.
So Elisha performed a bold, prophetic act. He threw salt in the water and proclaimed: "Thus says the Lord, ‘I have purified these waters; there shall not be from there death or unfruitfulness any longer'" (v. 21, NASB). His proclamation brought immediate cleansing.
