If any reader of this book really feels that he has counted the cost, and taken up the cross, I bid him persevere and press on. I daresay you often feel your heart faint, and are sorely tempted to give up in despair. Your enemies seem so many, your besetting sins so strong, your friends so few, the way so steep and narrow, you hardly know what to do. But still I say, persevere and press on. The time is very short.
