In biblical theology, "this world" often refers to the present age or the earthly realm in contrast to the eternal kingdom of God. It is characterized by temporal concerns, material pursuits, and spiritual challenges that stand in opposition to the divine order and eternal truths of God's kingdom.

Nature and Characteristics

"This world" is frequently depicted as a place of moral and spiritual conflict. It is under the influence of sin and is often associated with values and systems that are contrary to God's will. In 1 John 2:15-17, believers are admonished, "Do not love the world or anything in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the desires of the flesh, the desires of the eyes, and the pride of life—is not from the Father but from the world. The world is passing away, along with its desires; but whoever does the will of God remains forever."

Spiritual Warfare

The New Testament frequently highlights the spiritual battle between the forces of this world and the kingdom of God. Ephesians 6:12 states, "For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this world's darkness, and against the spiritual forces of evil in the heavenly realms." This passage underscores the reality that the challenges faced by believers are not merely physical or social but are deeply spiritual.

Separation from the World

Believers are called to live in this world but not be of it. Jesus, in His prayer for His disciples, said, "I have given them Your word, and the world has hated them, for they are not of the world, just as I am not of the world" (John 17:14). This call to separation is not a withdrawal from society but a distinctiveness in values, priorities, and conduct that reflects the character of Christ.

Transformation and Renewal

Romans 12:2 exhorts believers, "Do not be conformed to this world, but be transformed by the renewing of your mind. Then you will be able to discern what is the good, pleasing, and perfect will of God." This transformation involves a renewal of the mind and spirit, aligning one's life with God's purposes rather than the fleeting patterns of this world.

Hope and Future Glory

While "this world" is marked by impermanence and decay, Scripture points to a future hope and glory that transcends the present age. In 2 Corinthians 4:4, the apostle Paul refers to "the god of this age" who blinds the minds of unbelievers, yet he also speaks of the eternal weight of glory that awaits those who are in Christ (2 Corinthians 4:17-18). This future hope encourages believers to persevere in faith and righteousness, looking forward to the new heaven and new earth where God's kingdom will be fully realized.

Conclusion

The concept of "this world" in the Bible serves as a reminder of the temporal nature of earthly life and the spiritual realities that believers must navigate. It calls Christians to live with an eternal perspective, prioritizing their relationship with God and their witness to His truth in a world that often stands in opposition to His ways.
