I just finished two great missions books: Thinking Outside the Box, by Charles Keen, and The Legacy of William Carey, by Vishal and Ruth Mangalwadi. The first book has some innovative ideas for reaching the world. The second book is a fascinating treatise on how Carey's ministry and influence changed India tremendously for the better. Just one example is how he campaigned for the abolition of "sati," the practice of burning widows alive with their husbands. However, the greatest book in this area I ever read was The Life of Adoniram Judson by his son Edward. I have a first edition from 1883. What is the best missions book you ever read? Are you reading a missions book right now or have you read one recently?
