Galatians 4:1-3

Think of it this way. If a father dies and leaves an inheritance for his young children, those children are not much better off than slaves until they grow up, even though they actually own everything their father had. They have to obey their guardians until they reach whatever age their father set. And that’s the way it was with us before Christ came. We were like children; we were slaves to the basic spiritual principles of this world.
