This is one of those rare books that you should buy even if you know all the basic facts in it already -- and if you've read Tekton material for any length of time, you do. Richards and O'Brien give us the rundown on all those cultural facets of the Biblical world -- like honor and shame, collectivism, patronage, and so on -- that make it so vastly different than the world of the West.
What makes Misreading Scripture with Western Eyes special is that the authors have spent a good deal of time ministering in Indonesia, which gives them the chance to illustrate some of those differences with real-life examples from a parallel culture. Therefore, even if you do know all the factual material, it's worth having the book for these examples.
There's one more reason to buy it: It will encourage IVP and other publishers to produce like it. Encourage them to do so -- buy a wheelbarrow, then fill it with copies of this.
