Is the goal to grow numbers, or faith?  Maybe those sermons will inspire someone to volunteer at the local food shelf, or offer help to the elderly person next door, or contribute more generously to charity.  I'm less concerned with filling seminaries than I am about how people perceive and treat each other.  That's where sin comes from -- refusing to see the face of Christ in each other, or worse, claiming to see the face of Christ and still to ignore or abuse or walk away.
