First the Lord rescued John's family from sin and bondage to demons. Then he sustained them through some of the most desperate circumstances anyone has ever gone through. It's an amazing testimony to God's power and love. Not that John saw it at every step, but he trusted the Lord and the Lord provided for him. Even when he wasn't obeying the Lord, God never forsook him. It's just a beautiful testament of forgiveness.
Never do they sugar coat the Gospel. Sin called sin. Repentance is handled Biblically. The Gospel is given fully. It was very refreshing to find all of those in a new Christian biography.
One of the most encouraging things about the whole book is the reliance on God's written Word. It was so precious to them through everything. They truly were Bereans; testing everything by the Word.
You should really read it. I can't think of a better way to explain this book than to quote form the preface.
'John’s story is not just about John. “If you tell them anything, Lilly, tell them what Jesus has done.” For that reason, this book is also the story of God as told through his people. It is the story of the God who rescues and saves. It echoes of Moses and the Israelites narrowly escaping the waters, of David taking down Goliath, and of Jesus tearing down the tables in the temple. It is a story of biblical proportions and, as with all the stories of the Bible, it reaches its height and discovers its depth with the one who gives the story meaning--Jesus the Word Incarnate. That Word, spoken thousands of years ago, is the Word that was spoken to John and his brothers and sisters in Sudan. It is the same Word that is spoken to us, no matter who or where we are. It is the same Word that speaks to us in this particular moment, no matter where the moment may fall, “I have come so that you may have life and have it to the full” (Jn 10:10)."'
