It was Mr. Spurgeon, I believe, who used to say to young men – “If you can do anything else do it. If you can stay out of the ministry, stay out of the ministry.” I would certainly say that without any hesitation whatsoever. I would say that the only man who is called to preach is the man who cannot do anything else, in the sense that he is not satisfied with anything else. This call to preach is so put upon him, and such pressure comes to bear upon him that he says, “I can do nothing else, I must preach.”
