The fact that this child felt the need to tell the truth is a great sign though. Im 100% positive God is calling Him to the truth, which would include telling the truth.
I hope he stays on the right path he is being led to. The only way for his salvation is through Christ, and it seems like he might be finding this out now :3
Maybe....... or it could have been someone was getting ready to expose the whole thing & they had to do it. After all the publishing company lost a bundle & may have demanded they confess as part of their settlement.
