One 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.’"

Vance 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 the track"
