"Partners with God" joke

(I don't know where this joke comes from originally; I heard it from
my father, who says he heard it many years ago and doesn't remember
from whom.)
A farmer purchases an old, run-down, abandoned farm with plans
to turn it into a thriving enterprise. The fields are grown over with
weeds, the farmhouse is falling apart, and the fences are collapsing
all around.
During his first day of work, the town preacher stops by to
bless the man's work, saying, "May you and God work together to make
this the farm of your dreams!"
A few months later, the preacher stops by again to call on the
farmer. Lo and behold, it's like a completely different place-the
farm house is completely rebuilt and in excellent condition, there is
plenty of cattle and other livestock happily munching on feed in
well-fenced pens, and the fields are filled with crops planted in neat
rows. "Amazing!" the preacher says. "Look what God and you have
accomplished together!"
"Yes, reverend," says the farmer, "but remember what the farm
was like when God was working it alone!"
