Found out about this book through a quote that a friend posted on Facebook:
“If you are a white Christian wanting to be a missionary in this day and age, and you have never had a nonwhite mentor, then you will not be a missionary. You will be a colonialist. Instead of taking the gospel message into the world, you will take a [Western] version of the gospel.” (Soong-Chan Rah, The Next Evangelicalism, p.162)
Wow! I would love to read that book.
