For your Sunday sermon - The Drum Major Instinct by Martin Luther King

the source of my old signature line
"everybody can be great, (Everybody) because everybody can serve. (Amen) You don't have to have a college degree to serve. (All right) You don't have to make your subject and your verb agree to serve. You don't have to know about Plato and Aristotle to serve. You don't have to know Einstein's theory of relativity to serve. You don't have to know the second theory of thermodynamics in physics to serve. (Amen) You only need a heart full of grace, (Yes, sir, Amen) a soul generated by love. "
as well as the controversial quote at the MLK memorial
"Yes, if you want to say that I was a drum major, say that I was a drum major for justice. (Amen) Say that I was a drum major for peace. (Yes) I was a drum major for righteousness. And all of the other shallow things will not matter. (Yes) I won't have any money to leave behind. I won't have the fine and luxurious things of life to leave behind. But I just want to leave a committed life behind. (Amen) And that's all I want to say."
