Satan
Satan has many workers in this world that stir up confusion among the people. There are gonna be many that say here is christ there is christ, this is all prophecied and a very big part of showing we are at the end days. In the end there will be no atheist, no cults, no satanist, and no man made religions. They that did not accept Jesus Christ will know that He is God. He is the only God, and He is eternal.
