In the same manner, the mantle of the Holy Spirit that came upon Jesus in the Jordan River came upon the Church in the upper room on the Day of Pentecost. Therefore, the mantle is the power of the Holy Spirit. Elisha now has power over the water. In 2 Kings chapter 5, Elisha sends Naaman to the Jordan, and he dipped seven times, and Naaman was healed. God is about to reveal this power over the waters to His prophets.
Water gives life.
Jesus gives living water. The living water that produces everlasting life. Satan comes to pollute the living water and set up strongholds in the waters of the world to keep people from the living waters of God. The mystery now being revealed is that he has assigned spirits to at least some locations to dwell in the waters as a position of spiritual authority from which to influence the people of the world. Verse 5 refers to the angel of the waters.
