The concept of living as foreigners is a recurring theme throughout the Bible, reflecting the transient and pilgrim nature of the believer's journey on earth. This theme is deeply rooted in the understanding that Christians, while living in the world, are not of the world, and their ultimate citizenship is in heaven.

Old Testament Foundations

The idea of living as foreigners is first introduced in the Old Testament with the patriarchs. Abraham is a quintessential example, as he was called by God to leave his homeland and live as a foreigner in the land of Canaan. In Genesis 23:4, Abraham refers to himself as "a foreigner and a stranger among you" when negotiating for a burial site for his wife Sarah. This acknowledgment of his status as a foreigner underscores his faith in God's promises, looking forward to a future inheritance.

The Israelites' experience in Egypt further illustrates this theme. They lived as foreigners in a land not their own, which is highlighted in Exodus 22:21, where God commands, "You must not exploit or oppress a foreigner, for you were foreigners in the land of Egypt." This commandment serves as a reminder of their own past and a call to empathy and justice.

New Testament Teachings

In the New Testament, the theme of living as foreigners is expanded to encompass the spiritual journey of all believers. The Apostle Peter addresses this directly in his first epistle: "Beloved, I urge you as foreigners and exiles to abstain from the desires of the flesh, which war against your soul" (1 Peter 2:11). Here, Peter emphasizes the temporary nature of the Christian's earthly existence and the call to live a life set apart from worldly desires.

The Apostle Paul also speaks to this theme, particularly in Philippians 3:20: "But our citizenship is in heaven, and we eagerly await a Savior from there, the Lord Jesus Christ." This verse highlights the believer's true identity and allegiance, which transcends earthly nationalities and affiliations.

Practical Implications

Living as foreigners has practical implications for how Christians conduct themselves in the world. It calls for a lifestyle that reflects the values and principles of God's kingdom rather than conforming to the patterns of this world (Romans 12:2). Believers are encouraged to live with an eternal perspective, investing in what is lasting and eternal rather than temporary and fleeting.

Moreover, this perspective fosters a sense of hope and anticipation for the future. Hebrews 11:13-16 speaks of the heroes of faith who "acknowledged that they were strangers and exiles on the earth" and "were longing for a better country—a heavenly one." This longing for a heavenly homeland inspires believers to persevere through trials and challenges, knowing that their ultimate reward is with God.

Community and Witness

The concept of living as foreigners also influences how Christians interact with the broader community. As ambassadors of Christ (2 Corinthians 5:20), believers are called to represent the values of God's kingdom, serving as a light to the world (Matthew 5:14-16). This involves showing love, compassion, and hospitality to others, including those who are themselves foreigners or marginalized in society.

In summary, living as foreigners is a profound biblical theme that shapes the identity, conduct, and mission of believers. It calls Christians to live with a heavenly perspective, embodying the values of God's kingdom while journeying through this temporary world.
