Bro. Fred Carlson spoke with me about his 30+ years of involvement in the mission field. He personally served as a missionary pilot and church planter in various countries. Currently he is teaching missions classes in a college setting.
In this interview he explains a bit about his ministry on the foreign field and tells about some of the missions classes he teaches. I was surprised, in a good way, by one of his answers to my question about which classes someone should focus on while preparing to be a missionary on a college level.
