University to go to the library and pick out the
books on his subject (midwifery) that were no longer needed. His reply
to the librarian was this:

"Take every text-book that is more than ten years old and put it down
in the cellar."

Sir James Simpson was a great authority only a few years ago: men came
from all parts of the earth to consult him; and almost the whole
teaching of that time is consigned by the science of to-day to
oblivion. And in every branch of science it is the same. "Now we know
in part. We see through a glass darkly." Knowledge does not last.

Can you tell me anything that is going to last? Many things Paul did
not condescend to name. He did not mention money, fortune, fame; but
he picked out the great things of his time, the things the best men
thought had something in them, and brushed them peremptorily aside.
Paul had no charge against these things in themselves. All he said
about them was that they would not last. They were great things, but
not supreme things. There were things beyond them. What we are
stretches past what we do, beyond what we possess. Many things that
men denounce as sins are not sins; but they are temporary. And that is
a favorite argument of the New Testament. John says of the world, not
that it is wrong, but simply that it "passeth away." There is a great
deal in the world that is delightful and beautiful; there is a great
deal in it that is great and engrossing; but

IT WILL NOT LAST.

All that is in the world, the lust of the eye, the lust of the flesh,
and the pride of life, are but for a little while. Love not the world
therefore. Nothing that it contains is worth the life and consecration
of an immortal soul. The immortal soul must give itself to something
that is immortal. And the only immortal things are these: "Now abideth
faith, hope, love, but the greatest of these is love."

Some think the time may come when two of these three things will also
pass away--faith into sight, hope into fruition. Paul does not say so.
We know but little now about the conditions of the life that is to
come. But what is certain is that Love must last. God, the Eternal
God, is Love. Covet, therefore, that everlasting gift, that one thing
which it is certain is going to stand, that one coinage which will be
current in the Universe when all the other coinages of all the
nations of the world shall be useless and unhonored. You will give
yourselves to many things, give your
