The Bible is full of references to shepherds and the care of sheep but very rarely dairymen and the care of cows.
In one corner of England, on the edge of the Forest of Dean, Counties worker Tim Cracknell with his wife Katrina are part-time dairy farmers and full-time evangelists and have seen a remarkable mini-revival around them.
The couple, who live on the farm where Tim was born 50 years ago, have just celebrated the eighth birthday of a local church which, in 1999, had effectively died.
