In the book The Vance Havner Devotional Treasury, the author wrote, "I shall never forget Dr. R.A. Torrey saying to me as a young preacher, 'Young man, make up your mind on one thing and stick to it.'" Havner comments, "The Christian life should be like a sword with one point, not like a broom ending in many straws. Such a single purpose forgets the past, reaches toward the future, and presses on. There is no time or place for side issues, diversions to the right or to the left. There is no place for hands on the plow with eyes looking back. Paul was a one-track man, but you can go a long way on one track!"
