There are true believers gathering in true churches, but often with imposter leaders. The sin of tolerating these leaders is a destructive force preventing growth in the knowledge of Jesus Christ and God who sent him. It is just like the times scripture records of the prophet Elijah, and of Jezebel with her husband King Ahab. The sin of Jezebel was so famously revealed by Elijah on Mount Carmel. Yet it took great courage and moral fortitude for the people in the palace of Jezebel and Ahab to throw down Jezebel. Today the true believers lack this fortitude and courage. Warmongers, imposters, false leaders are tolerated too long. They blot out the light from the fellowship. The light, which once shone bright on Carmel, is hidden from the true believers, so, though they have the Holy Spirit, their growth in Christ is hindered. This is like the letters of resurrected Jesus Christ in the Book of Revelation. The false ones need to be expelled, not tolerated.
