this one would be worth a try.
So of course I had to read it and make an assessment.
THere are, naturally, 4 sessions (to correspond with 4 Advent Sundays). Though the study would likely start in November to finish by mid December for scheduling purposes. The 4 sessions essentially correspond to the 4 ghosts: Bah humbug deals with Marley; The Remembrance of Christmas Past with the Ghost of same; The Life of Christmas Present; The Hope of Christmas Future which also looks at the closure of the story and how Scrooge is transformed and Redeemed.
It looks like it would make a good study. It gives a new way to look both at the Advent season of preparation and Christmas through the lens of a beloved Christmas story. There are times where the links to the Scrooge story are a bit more tangential than a focal point but on the whole it works. Not sure how it will translate into a worship series but the story of transformation is a clear part of the trory of Christmas.
I think it is worth a try. Only way to find if it works -- right?
