I think the author does an average job of making D.L. Moody's biography compelling, while knitting together all of the disparate locations and people that were involved in or touched by Moody himself while he was alive.
I rate this book 3 stars instead of higher because of the moderately terse prose. However, it is not as bad as some biographies I have read, and in writing a biography I feel that an author has to constantly fight against a habit of just listing out names, dates, places and years, but instead turning them into a narrative and finding ways to correlate key events across time and place to put them in relation to other well-known people and events so that the biography becomes more relatable to the average reader.
The best part of this biography is about the first 1/4 of the book, recounting Moody's early life and his strong entrepreneurial urges and good, innate business acumen. Moody comes up as an assistant to a shoe salesman, and learns some hard lessons along the way that resonate deeply with him. It seemed clear to me, as a reader, that Moody was a very self-motivated individual who wanted to be the best at whatever it was he did in life, and while a young man he wanted to become the most successful shoe salesman he could be in Chicago. One of Mr. Moody's coworkers influenced D.L. to accept Christ into his heart and become saved. From then on, the repeated line is the theme of this biography and of Moody's life: "The world has yet to see what God can do with one man wholly committed to Him." D.L. literally pours his entire physical, mental and spiritual strength into serving God, especially through ministry to young children in the city of Chicago, and later, in ministry and evangelism throughout the world. During this time period, where travel across the Atlantic between the U.S. and Europe was possible but still time consuming and relatively dangerous, I became concerned for Moody's physical well-being as he continually pushed himself onward to reach more people in more places. I am conflicted about Moody and George Whitefield in particular, in that perhaps they should have learned more self control or better paced themselves to protect their physical health. And yet, Moody lived to be 62, dying in 1899, and George Whitefield lived to 55 in 1770, despite physical ailments during their lifetimes.
I think that Moody's coming to Christ through a child-like, basic understanding, is what enabled him to be so successful an evangelist to peoples and cultures around the world - he understood that keeping the message simple but true and relevant, was the key to imparting God's love to the world.
