When preaching in Chicago, Dr. Monro Gibson once asked in the inquiry
meeting, "Now, how can we find out who is thirsty? I was just thinking
how we could find out. If a boy should come down the aisle, bringing
a good pail full of clear water and a dipper, we would soon find out
who was thirsty. The thirsty men and women would reach out for water;
but if he should walk down the aisle with an empty bucket, we wouldn't
find out. People would look in and see that there was no water, and
say nothing. So," said he, "I think that is the reason we are not more
blessed in our ministry; we are carrying around empty buckets, and the
people see that we have not anything in them, and they don't come
forward."
