Proverbs 22:6 is referenced, along with John 3:16 and Philippians 4:6-7.   One character states he follows Jesus now---and it certainly seems to be true, considering his actions & behavior.  Another thinks to himself how he's been a "Christian" since he was five (presently he's 15).  Two characters pray rather passionately on behalf of another.

Overall, it was a cute, super easy read---only 46 pages.  While it's certainly geared for those around the ages of 8/9ish to 12 or so, there are some themes that may seem both too mature and/or too childish.

I will say one thing in regards to the strong Christian theme:  One character reminisces on that he was saved at the age of five, implying that he raised his hand after saying "the prayer"---this could give young readers the wrong idea of salvation in that one needs only to pray in order to be saved, when in truth, one must simply believe.  I'm not saying that the character wasn't saved, only that his thinking can influence and/or certainly relate to others.  He saw the good 'fruit' of his transformed cousin, and I believe it was a point in this short story that he was perhaps just "going through the motions" as a generational Christian compared to his radically changed cousin, who would've previously been considered a troubled kid/rebel.  All that said, it is probably that particular theme that would seem a bit over the heads of young readers.

To conclude, it's a clean & easy read for the targeted group. :]
