Some years ago, musicians noted that errand boys in a certain part of London all whistled out of tune as they went about their work. It was talked about and someone suggested that it was because the bells of Westminster were slightly out of tune. Something had gone wrong with the chimes and they were discordant. The boys did not know there was anything wrong with the peals, and quite unconsciously they had copied their pitch.

So we tend to copy the people with whom we associate; we borrow thoughts from the books we read and the programs to which we listen, almost without knowing it. God has given us His Word which is the absolute pitch of life and living. If we learn to sing by it, we shall easily detect the false in all of the music of the world.
