they are so delicately hung upon hinges. The hinges of
the doors of life are made not of brass or iron, but of love.

When, in a little while, you leave this church you will take hold of a
knob and pull open the door. The doors of life have knobs. Those knobs
are called courtesy. You can open well nigh any door you choose if only
you will use the knob courtesy.

What about the lock? Yes, doors have locks. So also have the doors of
life. Can you guess what locks the door of life? It is faith. If you
have faith, faith in God, faith in the Saviour, faith in things that are
true and pure, you need never fear that your house of life will be
broken into by burglars. You are secure if you have the lock of faith.
Now here is a strange paradox, namely--you lock your door only by
opening it. Open your door to the Master.

MEMORY VERSE, _Revelations_ 3: 20

"Behold, I stand at the door and knock; if any man hear my voice
and open the door, I will come in to him, and will sup with him
and he with me."

CHEAPEST AND BEST

A business man would not consider this subject a very good
advertisement. He believes that the best things are never cheapest.
There are a few instances however in which that is not the case.

First, the air we breathe. It does not cost us anything, it isn't
metered out to us, so we have a saying, "as free as air." You go down to
the drug store and buy a bottle of perfume. A good perfume will cost not
less than a dollar a bottle. The air we breathe is infinitely purer and
better than the costliest perfume.

Second, the water we drink. Do you like ice cream soda? I am sure you
do. If you do not you are not a normal girl or boy. How much do you have
to pay for a good ice cream soda? That depends; some places it is ten
cents and some fifteen cents. You think you might like to have ice cream
soda every meal, but you would soon tire of it. The water you drink is
necessary, and it costs you nothing.

Third, a book, that is this book, the Bible. If you wish to buy an
up-to-date book of fiction it will cost you anywhere from $1.00 to
$3.00. But here is a book, the most popular, the most wonderful book
that was ever written. You can buy a Bible for a few pennies, and if you
do not have the pennies there is a great Bible Society that will give
you a copy, that none may be without the Word of Life.

Finally, the things that are cheapes
