I Corinthians 1:26-29
New International Version
Brothers, think of what you were when you were called. Not many of you were wise by human standards; not many were influential; not many were of noble birth. But God chose the foolish things of the world to shame the wise; God chose the weak things of the world to shame the strong. He chose the lowly things of this world and the despised things—and the things that are not—to nullify the things that are, so that no one may boast before him.

The Soul of the Firm (p. 147), Harper Business
… one last word of advice: build on the ordinary and expect the extraordinary. Build your team of people around the talents and skills of the ordinary person, not just around the special skills and talents of those few extraordinary people. After all, there are many more ordinary people - more to select from; more potential to develop; more opportunity for commitment and loyalty to the common mission of the firm; and more potential to understand, serve, and sell the customer - most of whom, by the way, are also ordinary people.
