I was raised Church of Christ. When I was about 14, my parents bought me my first Bible. The basic attitude seemed to be "Here's the Bible, you figure it out, be downstairs for dinner later". Not sure if that's a Church of Christ policy or a My Parents policy. But either way, that was the policy.
It was some easy English version meant not just for kids. But (probably) for stupid kids, specifically. I forget the exact name of the translation but it takes a LOT of liberties with the text. "Life Application Bible" or some such. It had some kind of cheesy interludes with (allegedly real) high school students talking about life, the universe and everything. The applicability of several of those "Here's What I Did" interstitials was dubious even in the best cases. Overall, I don't recommend this as something for children.
Needless to say, it was a bit of a struggle. Began with Genesis and right around the time I got to Deuteronomy, I'd kind of lost the plot. If I ever had it. Which is 50/50, really. So I figured I'd skip ahead to St. Matthew's gospel.
Mind. Blown.
To this day, it's always been a bit of a struggle to invest myself into the Old Testament. Psalms, Proverbs and that stuff are fine. But other books therein can be a bit of a slog sometimes.
