Case for Christ for Kids by Lee Strobel
This is a kids book similar to The Case for Christ, by the same author. It's a good book and covers some basic questions - who was Jesus? Did he fit the Messiah picture? Did his friends tell the truth? Can a dead man really come back to life? Then the last few chapters are about young people sharing their faith through common encounters.
I think for where Matthew is in his faith, this book is a little young. Which is not to say that it's young for many 10 yos! Matthew is just very mature in his faith.
Recommended - yes.
