Rees Howells came from a poor family in a Welsh mining village, who more than enything else learnt the secret of prevailing prayer. This book tells how Howells faced the implications of full surrender, learnt to love the unlovely, found the key to prevailing prayer, became the channel of a revival in Africa, founded the Bible College of Wales, was taught the principles of divine healing and became a man who believed that prayer could alter the course of events in time of war.
