That is what the Scriptures mean when God told him,“ I have made you the father of many nations.” This happened because Abraham believed in the God who brings the dead back to life and who creates new things out of nothing.
All these people died still believing what God had promised them. They did not receive what was promised, but they saw it all from a distance and welcomed it. They agreed that they were foreigners and nomads here on earth.Obviously people who say such things are looking forward to a country they can call their own.If they had longed for the country they came from, they could have gone back.But they were looking for a better place, a heavenly homeland. That is why God is not ashamed to be called their God, for he has prepared a city for them.
