Heb 11:15, 16
And if indeed they had been mindful of that country from which they went out, they would have had opportunity to return. But now they desire a better country, that is, a heavenly: wherefore God is not ashamed of them, to be called their God; for he hath prepared for them a city.

                God has prepared a city in heaven for His people. All that died in faith were looking for this heavenly city, for if they were looking for their own country they would have had time to return to it. They looked to the eternal things rather than to the temporal ones. The implication is that this world is temporary. The impact is that I should not place my hopes in this world but in the world to come. My prayer is that we will not be attached to this temporal world but to the eternal promised by God.
