“The greatest courage in the world is not the courage of an optimist. An optimist has courage because he believes the best will happen. The greatest courage in the world is the courage of the pessimist because he knows the worst is going to happen and is willing to go anyway.”

(John MacArthur, GTY “Matthew and Thomas Part 2” 6/8/07 – this quote is in the context of the pessimism of Thomas, the apostle, and his devotion to Christ))
