As a teenager, John was called to serve God in mission and, as a result, he trained in medicine. But when he eventually embarked on his calling, his personal circumstances called into question the whole idea. Shouldn't God's servants be "walking in victory"? This is the story of how God can and does use flawed, weak persons in His own mission. Have you thought of volunteering to work in poor ports of the world? Many people do, it's a chance to "give something back." But there are many obstacles to overcome. This book explores many of the issues that one person faced, honestly describing both highs and lows. The author thought his medical skills would be useful, but he found he had to be flexible, doing what was needed in each circumstance. A key early task was working with "street children" in Brazil and this opened doors to quite different work which took him to the far-flung corners of the globe.
