Gospels for Asia are offering a free hard book back called Revolution in World Missions by Dr. K.P. Yohannan. There is a video below of Francis Chan giving a ringing endorsement for why you should just get and read this book.
I’ve ordered mine, here is the synopsis given on the website:
Step into the story of missionary statesman Dr. K.P. Yohannan and experience the world through his eyes—from the villages of India to the shores of Europe and North America. Watch out: His passion is contagious!
With fascinating true stories and eye-opening statistics, you’ll be challenged to examine and change your lifestyle in view of millions who have never heard the Gospel.
