Leaf by Niggle by Tolkien Posted on January 7, 2013 by budderpopcorn 6 Leaf by Niggle, by J.R.R. Tolkien. Tim Keller mentions it — and carries its imagery throughout his book even — in Every Good Endeavor. Scot McKnight wrote about it in 2009 as a wonderful tale showing us a Christian way to view work. I read it. It is wonderful. And for some of us, even perhaps, relatable!
