Yeah exactly
I guess sort of like angels, as in just as the position of servant rather than a son. In a certain sense they were always His children, in the sense of creation, but not in like, a legal heirship sort of thing if that makes sense. For example, John 1:12 talks about those who believe being given the power to become sons of God, implying they weren't before they believed. And the born again thing wouldn't necessarily mean that we're part of God's family, it's talking about being born of the spirit, because we've inherited a dead spirit from Adam. But that's not necessarily the same as having the role of a son.
Exactly. God didn't have to save us, but He did. But I bring up that example because it shows how the son would have returned to his father, but at a lower status than sonship. The father however chose to welcome him back as a son.
It's kind of a nuanced difference, but I really don't think God had to give us the position of sonship once we were saved.
