Instead, they were longing for a better country—a heavenly one. Therefore God is not ashamed to be called their God, for he has prepared a city for them.
My favorite part of this verse is when it says, "Therefore God is not ashamed to be called their God..."
I know that there are times that I have felt ashamed to be hanging around with certain people. When I was out in public with them, I felt a little embarrassed. Maybe it was how they acted, or the way they looked. Whatever it was, my pride hindered me from wanting to be seen with them, because I did not want to be associated with them.
Sometimes that is a good thing. There are certain people who you would most definitely not want to be associated with, but it is not like that with God.
He is not ashamed to "be seen" with us, even though He is so much higher than we are. When we go out in public, He has no problem branding His own name on us. We have sought His city, a heavenly city, therefore He has prepared one for us.
