Documentaries have long been affective in reaching an audience. Documentaries about culture, religion, science, conspiracies, etc. have been a hit with people. Some documentaries take massive amounts of funding and production, but if one has a good video camera, then perhaps a 20- or 30-minute documentary on a topic would not be too difficult. An example could be "What is a woman?" or a documentary on a religious figure. One could also create documentaries specifically on Christian men who changed the world to show men of the kingdom what we should be doing.
