Head versus Heart

Psalm 23
Some years ago at a social event, a great actor who was an honored guest was asked to recite something for the pleasure of his fellow guests. He consented, and asked if there was anything special that his audience would like to hear.
After a moment's pause, an old clergyman present said: "Could you, sir, recite to us the twenty-third Psalm?"
A strange look passed over the actor's face. He paused for a moment, and then said: "I can and will, upon one condition; and that is, that after I have recited it, you, my friend, will do the same."
"I?" said the clergyman, in surprise. "But I am not an elocutionist. However, if you wish it, I will do so."
Impressively, the great actor began the psalm. His voice and his intonation were perfect. He held his audience spellbound, and as he finished a great burst of applause broke from the guests.
Then as it died away the old clergyman arose and began the psalm. His voice was not remarkable; his intonation was not faultless. When he had finished no sound of applause broke the silence—but there was not a dry eye in the room, and many heads were bowed.
The actor rose to his feet again. His voice shook as he laid his hand upon the shoulder of the old clergyman and said: "I reached your eyes and ears, my friends; he reached your hearts. The difference is just this—I know the twenty-third Psalm, but HE KNOWS THE SHEPHERD!"
Reader, do you? Can you say, "The LORD is MY Shepherd?"
