It is one thing to write a good book. It is another thing entirely to write a timely book, and given the choice, most people would settle for the latter. Melani McAlister does not have to make this choice, for with the publication of The Kingdom of God Has No Borders, she has managed to achieve both. She has written an absolutely brilliant and totally absorbing book on American evangelicals at the precise historical moment when American evangelicals and evangelical politics have come under persistent academic and public scrutiny, perhaps the most intense and most searching in a generation. We all know why. This book has suffered a protracted gestation, and the world into which The Kingdom of God is released is, morally and politically speaking, arguably a radically different one from that in which the idea for the book was originally conceived over a decade ago. But I cannot imagine Professor McAlister complaining. Good things usually come to those who wait, and she must surely feel that all that time spent trying versions of different chapters on audiences at workshops, conferences, and public lectures, and importuning an endless list of interlocutors, is justified by the exquisite timing of its eventual release.
