Query: Great man, great book

There needs to be a God, and there needs to be a heaven if just to reward someone like Pop Buell. A great man who should be studied. A very interesting read. The book was worth the search. No, you can't have my copy. Anyone who considers himself a Christian or a humanitarian can learn from Buell's example of true selfless service.
