There are four great temptations that plague most young men: sloth, lust, love of pleasure, and peer pressure. J C Ryle -- the last of the great Puritans -- tackles each of these subjects with a tenderness and tact which is unsurpassed. First written toward the end of the nineteenth century, it remains to this day the most relevant and helpful book on the subject in print. I was first introduced to Ryle about fifteen years ago, and he remains a favourite teacher on personal holiness.
