How does the concept of the world passing away affect Christian behavior?

The acknowledgment that the world and its desires are transient encourages Christians to live in light of eternity. In 1 John 2:17, John states that the world is passing away, along with its desires, but whoever does the will of God abides forever. This truth serves as a reminder to believers that their hope and identity are rooted not in the fleeting success or pleasures of this world but in their eternal relationship with Christ. This perspective shifts priorities, urging Christians to invest in eternal treasures and engage in righteous living that glorifies God. By aligning their behavior with God's will rather than worldly standards, believers reflect their true citizenship in heaven and demonstrate the transformative power of the gospel.
