Our feature guest this week, as you'd know, is Ronald Sider. Ron's book Rich Christians in an Age of Hunger has been described by Rob Seiple, the former President of World Vision in the United States, as “The most pivotal book in my Christian journey.” I know it’s been influential for a number of others too.

It got us thinking: Apart from the Bible (which most of us could mention!), what is the book that’s changed your life? It may have changed your approach, outlook or direction in life, challenged your way of thinking, or even opened your eyes to an issue that you never knew existed.

Tell me about the book that changed your life. What book was it, and how were you impacted?
