In “Famous Stories of Sam P. Jones” may be found this bit of wisdom:
A well-trained musician sits down to a piano and sweeps his
fingers over the keys. A cloud gathers on his face as he
recognizes a discord in the instrument. What is the matter?
Three of the keys are out of harmony. These three keys that
are out of harmony are out of harmony with everything in the
universe that is in harmony. I say to that musician, “Close up
that piano and let it alone until it puts itself in harmony.”
He replies, “It is impossible for the piano to put itself in
harmony.” “Who can put it in harmony?” I ask. He replies, “The
man who made the instrument. The instrument is put into the
hands of the man who made it, and in a few hours every key on
the piano is in harmony, and the piano being in harmony with
itself is in harmony with everything else in the universe.”
God alone can put discordant souls into harmony.
