The Biblical understanding is much different from this. Like the rest, we were by nature objects of wrath. Children are not born with a hunger for God. We have to teach a child to pray, to respect, to share, to love. It all comes naturally.
Every child is a potential savage.
Any child, if left to their own devices could become the next playground killer. Children need to be instructed in Godliness. It does not come naturally. They figured when their children got older they could more accurately choose. But that is nonsense.
