Charles Leiter (author of the book Justification and Regeneration - the top seller on the Monergism website) also visited Denmark recently with Paul Washer and had plenty of godly wisdom to impart. The subject of church discipline is HUGE. Many churches either don't do it or don't do it biblically. Tolerating sin in the camp is both a reproach on Christ and an unloving way to treat an unrepentant church member. This video is worth hearing for the wonderful illustrations Charles gives - including the story of when he had to subject his own daughter to biblical church discipline.
