Only in heaven will be known the effect that prayer has had in speeding the work of world evangelization. We may discover that it was the most powerful force exerted by the church in making a difference in this world. Ajith Fernando, National Director, Youth for Christ, Sri Lanka. A number of fundamental assumptions have been made in compiling this book. We realize that we will never satisfy all readers, but we trust that we have been sensitive to other theological and political points of view beyond our own. The people directly involved in the composition of this volume represent over 10 nationalities, 3 generations and 20 denominations. Even this is only a tiny proportion of the vast diversity in the body of Christ. Our own perspectives inevitably influence the selection of material and opinions expressed, and for these we must accept responsibility. All views here expressed are our own and not necessarily those of the publishers or of any organization mentioned in this book. We cherish constructive advice for future revisions and always endeavour to engage in fruitful dialogue with our critics. A number of these have eventually become some of our more helpful correspondents! - Operation World website.
