les, or as far as from
New York City to Des Moines, in the state of Iowa, or from New York City
down to the Gulf of Mexico.

I think you will now be able to understand what a wonderful little steam
engine and pump each of us has within our own breast. And it may
surprise you when I tell you that Dr. Buck says that the heart at each
throb beats with a power equal to 100,000 pounds.

An ordinary engine or pump would soon wear out, but this little engine
of the heart goes on beating day and night from the time we are born
until we are 70 years of age, if we live to be that old, and even while
we rest in sleep, the heart never stops for a moment. Is it any wonder
that David said that "We are fearfully and wonderfully made"?

I might tell you many other wonderful things about the heart, but this
will have to suffice.

If the natural heart in these bodies of ours is so wonderful, how much
more wonderful still is that heart which is the seat of the moral life
and character? As the natural heart is hidden away in these bodies of
ours, so the spirit or the soul is spoken of in the Bible as the heart,
because it is hidden away in the life which we have in these bodies of
ours; and it is this moral character and spiritual life to which the
Bible refers when it says, "Keep thine heart with all diligence, for out
of it are the issues of life."

QUESTIONS.--How did David say we are made? Does
the machinery in a great factory make much noise?
Are our bodies like a factory in this respect?
How can we hear the noise inside of our body?
Where is the heart located? What does the heart
do? Can you tell how water is supplied for a great
city? Is the blood carried to all portions of our
body in a similar way? How much blood is pumped by
the heart in twenty-four hours? What does the
Bible say is the allotted years of a person's
life? How long a string of teams would it require
to carry all the blood which the heart ordinarily
pumps in seventy years? Does the heart keep on
pumping while we sleep? What is still more
wonderful than the physical heart? Can we see
either the physical heart or the spiritual heart?
Does the fact that you cannot see them prove that
you do not have them? Are both necessary to your
complete being and existence?
