Excellent thread. Thank you all.

Valor is stability, not of legs and arms, but of courage and the soul. ~Michel de Montaigne

Courage is not the absence of fear, but rather the judgement that something else is more important than fear. ~Ambrose Redmoon

Every man has his own courage, and is betrayed because he seeks in himself the courage of other persons. ~Ralph Waldo Emerson

Raymond Irving Lindquist

Best known for the quote "courage is the power to let go of the familiar," Raymond Lindquist was the pastor at the Hollywood Presbyterian Church in Hollywood, California for many years. The author of the book Notes for Living (Philadelphia: Lippincott, 1968), Dr. Lindquist is said to have had the following about his profession: "Every great preacher had better be manic-depressive. He or she needs to be high at 11:00 on Sunday morning, preaching with all the confidence of divine authority. And that preacher had better be low by 2:00 on Sunday afternoon, or he will be impossible for his wife to live with the rest of the week."
