Mere Christianity


In Mere Christianity, C.S. Lewis aims to prove to the sensible skeptic that God does exist and that He sent His son Jesus Christ to redeem the world. The book begins with a logical proof for the Christian God and then transitions into a discussion of the common ground upon which all of those of the Christian faith stand together. Readers at all stages of belief will find that Mere Christianity provides an approachable path to discovering a powerful, rational case for the Christian faith.

This book is a must-read, at some point, for every believer.

How I Use this Book to make disciples

I tried to use this book as a complete read — meaning that I would have the group read the entire book and then review it. However, it seemed that so much truth got lost or misplaced on the way. My wife tried it chapter by chapter basing the amount read each week on how fast her group read. They would review the reading weekly. The results were incredible.

This book requires little extra prep or understanding by the leader. It is complete in its content and biblical support. It is not an easy read (it is written at a high school level or higher) so you need to make sure disciples have time to read and digest the truths. You do not want disciples to miss the content of this work.

Mere Christianity is one of the most comprehensive books ever printed to help the believer understand her faith. It is just that simple.

Real Life Story

Mrs. Porter gave this book to Doug, Sustainable Discipleship creator, in his first year of Christianity. He didn’t have the heart to tell her that it was too hard to read. It was just too much. He put it in a pile. A year or so later, Doug was bored sitting in his “cabana house” as a live-in pool boy for a rich family. He remembers working his way through Mere Christianity and feeling, “I am not alone. He gets me.” Doug tells how the truths began to fuel a better understanding of his faith. Now years and years later, Doug credits Mere Christianity as a foundational block in his faith.
