Some great teaching can be found on YouTube, some not so great. I like Chuck Missler among many others.
Chuck Missler is a good teacher and we have found a couple of teachers we keep up with. As I tell my students, drink the soup but spit out the bones. One very relevant, weekly prophecy update we enjoy is Pastor J.D. Farag out of Hawaii Calvary Chapel. He takes Scripture and applies it to today’s Headlines...very relevant.
