In case anyone is still interested in this - based on ray's version and brian's suggestions, this is what I think dwight is singing

Went to church the other day,
For to hear them sing and pray
Put your hand to the plow and hold right on

Hold on, hold on
Put your hand to the plow and hold right on

Preacher said we had to repent,
So right down the aisle I went

Never been to heaven but I've been told
It's a first class city and its features gold

Paul and Silas bound in jail
Had no one to go their bail

Paul and Silas began to shout
The jail bust open and they walked out

There stood Peter all nice and neat
Wouldn't let the saviour wash his feet

Peter got anxious and he said,
Wash my feet my hands and head

Got my hand on the gospel plow
Wouldnt pack a-nothing for my journey now
