Editor's note: This is the second installment of a three-part series by Dakotafire Media on the changing face of faith in rural Dakotas. The United Church of Christ in Gackle, N.D., is a traditional church building with angels in its stained glass windows. A few blocks away, Grace Baptist Church has a more modest style and could blend in with the residences around it if not for the steeple on the rooftop. But despite their differences, the two churches share one thing: the Rev. Tim Blackman's presence on Sunday mornings.
