Do children belong to their parents? Do they belong to the state? Do they belong in collectives to be raised by strangers?
None of the above despite what some might think.
Children belong to their Creator, not anyone else.
Children are on loan to parents but they are not the property of anyone but their Maker. It is up to parents to raise and nurture children in accordance with that truth realizing there will be an accounting.
Humans go pretty far off the path when they insist on inventing their own ideas of what is right and wrong.
