I can't tell if this question is trying to be funny or what. But if you are looking for a legit answer here it is. There are no "secrets" about the Bible. There are things that you may not find in the Bible like other history information. The Bible isn't meant to be a secret nor is it meant to be about ending child sacrifice. I have no idea where you got that from.
The Bible tells us about the Lord God, history, God's plan, and much more. The Bible also acts as an authoritative source. Besides the 4 gospels, Acts, and the book of Revelation, pretty much every other book in the New Testament is authoritative. The Bible is also meant to help us go through struggles through faith.
I hope everything I have said makes sense. If I have said anything wrong, I hope that my peers can help explain it better.
