"By faith Abraham, when he was called, obeyed by going out to a place which he was to receive for an inheritance; and he went out, not knowing where he was going. By faith he lived as an alien in the land of promise, as in a foreign land, dwelling in tents with Isaac and Jacob, fellow heirs of the same promise; for he was looking for the city which has foundations, whose architect and builder is God." Hebrews 11:8-10
Just like Abraham we need to be living in this world like a stranger in a foreign land. This world is not our home. we have a home eternal in the heavens.
"They are not of the world, even as I am not of the world." John 17:16We need to realize that we are only here on this earth only temporarily and live with our eyes set on our real home, heaven.
