The "Young Believer Bible" focuses on "What do believers believe?" This Bible, written for 8-12 year-olds, encourages children to "Never stop believing." I only had the Gospel of John to review; however, there are many commentaries, go-to references, and biblical paraphrases that are easy to read written in a language designed to appeal to young readers.
The "Young Believer 365 Devotional" includes stories, scripture verses, and prayers designed to provide ways for children to consider their Christian faith. The devotions offered are brief, but provide an avenue for journaling, discussion, or further thought.
The "Young Believer Case Files," contain true stories of youth who struggle with preteen problems and solve them through belief and faith in Christ. These stories are designed to help a child think through problems and find solutions prior to encountering them in real life.
These books were interesting, and probably would appeal to the young people to which they are targeted; however, they should not replace the Bible. I feel that authors often "water down" the Bible due to a feeling that it is too hard to understand, too hard to apply. Further, I feel uncomfortable recommending that young people read these materials in the absence of parental input. This type of material, if used in the home, seems appropriate to tackle as a family, or as a one-on-one discussion between a child and parent. I would not recommend just giving these materials to a child to go off on their own to read.
I also feel uncomfortable recommending that a Sunday school teacher or youth pastor be given these materials for use with 8-12 year-olds. These are, in my belief, topics to be discussed by children with parents.
In summary, materials like the "Young Believer" series, should be approached with caution. I would not recommend these materials be given to a 8-12 year-old unless the parent is involved in the reading and resulting discussions.
