We pay a heavy price for our fear of failure. It is a powerful obstacle to growth. It assures the progressive narrowing of the personality and prevents exploration and experimentation. There is no learning without some difficulty and fumbling. If you want to keep on learning, you must keep on risking failure all your life.
One of my less pleasant chores when I was young was to read the Bible from one end to the other. Reading the Bible straight through is at least 70 percent discipline, like learning Latin. But the good parts are, of course, simply amazing. God is an extremely uneven writer, but when He's good, nobody can touch Him.
