The preacher must live a life of large accumulation. He must not be always trying to make sermons, but always seeking truth, and out the truth which he has won the sermons will make themselves... Here is the need of broad and generous culture. Learn to study for the sake of truth, learn to think for the profit and the joy of thinking. Then your sermons shall be like the leaping of a fountain, and not like the pumping of a pump.
