A recent sermon from fundamentalist evangelist Tom Farrell offers an example of the use of social action in missions. Speaking of a missions trip to Thailand with an optometrist, Farrell said that the work of the doctor "gives us an opportunity to share our faith."
My sense is that fundamentalists more consistently connect social action with the proclamation of the gospel message than folks in the neo-evangelical stream, but that's simply my perception based on no scientific data. I think that's the mission Farrell is describing here:
What God is allowing us to do with our ministry and with Operation Renewed Hope is touch the body to touch the soul. And we're convinced of this: If we can touch the body of these dear folks, they will be open to the presentation of the gospel.Listen to his message, "Let's Be a Barney," here.
