Certainly worth reading, although I can't make much sense of the new title. (It was first published as 'Promoting the Gospel', which fit the content perfectly.)
The book drives us back to see what the Bible says about the gospel's spread. I didn't agree with all, but loved Dickson's insistence that I go and look at the Bible, rather then rely on what I've always done/thought.
The writing is, as always, smooth and clear.
What's best - the reminder of how great and good is the message of Jesus' ministry, and how great and good God is in providing so many ways to help gospel proclamation.
