Most families go wrong, each in its own predictably unpredictable way. Even parents’ best attempts at forming a healthy family usually backfire because of the arbitrary ways humans respond. Try to be caring and children feel smothered. Let them roam freely and they feel abandoned. Model respect and love and children will pick up a perfectionist vibe and conclude imperfections are not tolerated.
Family is a real challenge. Family is the place where we long to be most safe, yet it is also where we are most vulnerable and most dangerous. And most hurt.
So why should we imagine that it's "good news" that God has a family?
