What does the Bible say about being a stranger in the world?

In 1 Peter 2:11, believers are explicitly referred to as strangers and pilgrims, emphasizing their transient status in this world. This concept finds its roots in the experience of the nation of Israel, who were strangers in Egypt, a type representing the world. Once redeemed, they were instructed not to oppress strangers, reflecting an understanding that they, too, had once been outsiders. The apostle Paul highlights this change, stating in Ephesians 2 that those who were once strangers from the covenants of promise are now brought near by the blood of Christ, signifying their new identity as children of God who live in a world that is not their ultimate home.
