What does the Bible say about Christians being strangers and pilgrims?

In 1 Peter 2:11, the Apostle Peter exhorts believers as 'strangers and pilgrims' in this world. This terminology emphasizes that Christians have a different allegiance and home, which is in heaven rather than on earth. Just as pilgrims do not settle permanently in a foreign land, believers are called to live with the understanding that this world is not their ultimate home. Our true citizenship is in heaven, as the Apostle Paul states in Philippians 3:20, reminding us that we are merely sojourners on our way to our eternal dwelling with God.
