Rick,
Without a doubt, the central focus of any preaching ministry should be on the more positive elements of the Gospel. Just as I look down on preachers who preach nothing but love (no call for repentance, etc.), I also look down on preachers who preach nothing but fire. A church requires a balance in order to remain healthy. Your approach is the correct one.
