Rejoice in the Lord always: and again I say, Rejoice.…
If you go into Steinway's manufactory and strike certain chords of the powerful instruments, the chords of the other instruments, though they are covered up and apparently mute, will sound. Such are the correspondences which exist between them, such is the sympathy which is communicated from one to the other by the air, that when one vibrates, all vibrate. Though the sound be low and almost inaudible, it is there. When the grandeur, beauty, and love of the Divine nature are presented to a man, they draw some response from every part of his nature which corresponds to that which is presented. When the hearts of men are drawn towards the heart of God there begins to be an interplay between them; and thus Christian rejoicing, while only possible, is inevitable, "in the Lord."
(H. W. Beecher.)
