This book has been written by someone who sincerely wants to spell out what Jesus meant when he said, Unless . . . you cannot be a follower of mine and You cannot be be a follower of mine unless . . . As such it is a profoundly disturbing read. In just a few pages (it is a short paperback), Macdonald makes it very clear as to what Jesus requires of a Christian, going on to give live examples of people who have taken Jesus at his word. This book shocked me out of complacency, and was the beginning.
