Not My People, adopted

"I will say to Not My People, ‘You are my people’;" - Hosea 2:23

I wonder what we would do if this read "I will say to the Gentiles, 'you are my children';"? Would we respond differently if it was spelled out for us?
How often do we realize just how big of a deal it is that before Jesus we were just "Not My People." We we're the child of an unfaithful wife. Now because of who the Lord is, because of His overwhelming love for us, we're his children.

And he knew this all along. His plan was to die for us even back when our forefathers were living lives of unfaithfulness.
