If you consider yourself a first world missionary and you haven’t read Roland Allen’s Spontaneous Expansion of the Church and The Causes Which Hinder It, then you really need to get cracking.

I discovered the text of the book today on Steve Addison’s site in PDF format. (Steve has a stash of really good stuff!)

This is a gem.

I am also reading Christianity Rediscovered at the moment. It is another great missionary book, where Vincent Donovan explores what the gospel looks like for the Masai people.
