I don't have the video anymore, but basically a young Christian around college age doubts his faith and comes to his parents with his doubts. They are the usual doubts. The parents who are missionaries in the Philippines say well they have the doubts too, but they noticed after spending all their lives teaching others about their personal relationship with God that the native people were better off and happier since they came there. So even though they have a personal relationship with God and God speaks to them, they still doubt it and have to interact with the people to know the person they have a relationship with is real.
