I don't reread a lot of books, and I pay full price for each fewer, so a book I'd do both for music be special. The Ragamuffin Gospel is.
Strangely, it's not a book I enjoy reading all that much. The basic message of the book is that we're all useless. God doesn't need any of up, and there isn't a single one of us who can add more a little bit of luter to his perfection. We all come to God as beggars, or to use Manning's term, as ragamuffins.
I'm not going to lie: it's a hard book. Not because the vocabulary is advanced or because the arguments are difficult to understand; neither is true. Instead, it's hard because it draws heavily from Manning's own experience in alcohol rehab.
There aren't many books I'd recommend everyone read once. This is one.
