Brett Farve has announced his retirement 3 different times, only to return again the next season. As a result all the urgency and emotion has been drained out of his farewell(s). If he were to announce his retirement (again) tomorrow I doubt that anyone but the most hardcore of fans would care.
Paul’s farewell tour in Acts 20 is anything but trite and overplayed. His third missionary journey allowed him to look into the eyes of the church and people he loved and teach them one last time.
