Mark Baker suggests that just as car companies test automobiles under severe conditions to uncover weaknesses, North American Christians may detect fallacies in their "gospel" by examining how it plays out under the challenges of poverty, injustice, and entrenched religiosity. Baker's test case is drawn from his ten-year missionary experience in Tegucigalpa, Honduras, at churches born out of North American mission work.

Baker observes Honduran church life, draws parallels to the dangers of religion in the North American church and mines from Galatians exciting possibilities of robust Christian grace and freedom. The result is a bracing and refreshing approach to Christian community for laypersons, pastors, missionaries, and mission strategists.
