What Does It Mean To Be In The World But Not Of The World?
Understanding “In the World, But Not Of the World”
One of the most intriguing and often-quoted biblical concepts is the idea that believers are called to live “in the world, but not of the world.” This phrase encapsulates a profound theological truth about the Christian’s relationship with society, culture, and personal holiness. But what does Scripture really teach on this subject? Let’s explore the biblical foundations, practical implications, and encouragements for living out this calling.
The Biblical Foundation
The phrase itself is not a direct Bible quote, but its meaning is deeply rooted in Jesus’ own words. In His high priestly prayer, Jesus prays for His disciples:
I have given them thy word; and the world hated them, because they are not of the world, even as I am not of the world. I pray not that thou shouldest take them from the world, but that thou shouldest keep them from the evil one. They are not of the world even as I am not of the world. - John 17:14–16 ASV
Here, Jesus distinguishes His followers from “the world”—not geographically, but spiritually and morally. He emphasizes that while His disciples remain present in the world, their identity and allegiance are no longer governed by the world’s system, values, or priorities.
What Is “The World” in Scripture?
In the New Testament, “the world” (kosmos in Greek) can refer to:
- Humanity in general (John 3:16 ASV)
- The created order (Acts 17:24 ASV)
- The fallen moral and spiritual system opposed to God (1 John 2:15–17 ASV)
When Jesus and the apostles warn about “the world,” they refer to this last sense—the system of values, beliefs, and behaviors that are contrary to God and His kingdom.
Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him. - 1 John 2:15 ASV
Living “In” the World
Believers are clearly called to remain in society—not to withdraw or isolate themselves. Jesus Himself was known as a friend of sinners (Luke 7:34 ASV). The apostle Paul affirms the same, urging Christians not to separate completely from unbelievers, for then they “must needs go out of the world” (1 Corinthians 5:10 ASV). Instead, Christians are called to be “salt” and “light” (Matthew 5:13–16 ASV), influencing the world for Christ.
Not “Of” the World
While present in the world, Christians are not to adopt its sinful patterns:
And be not fashioned according to this world: but be ye transformed by the renewing of your mind, that ye may prove what is the good and acceptable and perfect will of God. - Romans 12:2 ASV
This call to transformation means resisting worldly values such as materialism, pride, immorality, and self-centeredness. Instead, believers are to reflect Christ’s character and priorities.
The Centrality of Christ
The key to living “in the world, but not of the world” is union with Christ. Jesus did not simply give rules for outward separation—He prayed for our inward transformation. Through faith in Christ, believers receive a new nature (2 Corinthians 5:17 ASV) and the indwelling Holy Spirit, empowering them to live distinctively.
I have been crucified with Christ; and it is no longer I that live, but Christ liveth in me: and that life which I now live in the flesh I live in faith, the faith which is in the Son of God, who loved me, and gave himself up for me. - Galatians 2:20 ASV
Practical Implications
- Engagement, not Escape: Believers are called to engage their culture as witnesses, building relationships, serving others, and sharing the gospel (Matthew 28:19–20 ASV).
- Discernment, not Conformity: Christians must prayerfully evaluate media, entertainment, and cultural trends, holding fast to biblical truth (Philippians 4:8 ASV).
- Holiness, not Legalism: Separation from the world is not about legalistic rules, but pursuing Christlikeness out of love and gratitude (1 Peter 1:15–16 ASV).
Encouragement for the Christian Life
Being “in the world, but not of the world” is challenging, but God provides all we need for faithfulness. Jesus promises His presence and protection (John 16:33 ASV). Our hope is not in escaping the world, but in shining for Christ within it, awaiting the day when He will make all things new.
