I was thankful to hear Dr. Billy Graham say, when addressing some six hundred ministers in London in November, 1970, that if he had his ministry all over again he would study three times as much as he had done. “I’ve preached too much and studied too little,” he said. The following day he told me of Dr. Donald Barnhouse’s statement: “If I had only had three years to serve the Lord, I would spend two of them studying and preparing.”
