This video is from one of the "revival" meetings in Lakeland, Florida:
"Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world" (1 John 4:1).
There was a quote in "And the Shofar Blew" that fits this video well. It was a conversation about how a church was growing so rapidly and one of the people stated something along the lines of "God must be in this...look how many people have joined." The older gentlemen responded to the comment by saying, "Just because something grows doesn't mean it's good. Cancer grows."
