One thing thatboth had in common was that they were led to live in foreign lands, among foreign people...pulled away from their native homes. And yet, it was precisely in this context that they learned how to listen to God, hear His promise, trust in Him and see Him defend from harm and provide all needs. They became close to God when they were far from home. I think this is an apt picture of our walk with the Lord, as well. As believers in God, through our faith in Jesus Christ, we are surrounded by foreigners who have no such allegiance. And yet this is when we realize our need to depend on Him most and this becomes our opportunity to reflect His reality to others. Our faith is deepened as we face contrast and conflict and then realize the provision and protection of the living God. One outcome in Isaac's life was new covenants of peace that were forged with some of the foreign people who saw the reality of God in him. When we live in a foreign land we are more likely to depend on God rather than ourselves. And we are more likely to reflect Him properly to others.
And our true home is in Heaven!
Genesis 26:3 Live here as a foreigner in this land, and I will be with you and bless you. I hereby confirm that I will give all these lands to you and your descendants, just as I solemnly promised Abraham, your father.
