How can Christians demonstrate they do not love the world?

In John 6:29, Jesus emphasizes that the work of God is to believe in Him whom He has sent. This belief manifests itself through obedience to God's will, which becomes the criterion by which believers demonstrate their commitment to Christ and rejection of worldly values. By actively engaging in doing the will of God—seen through a life committed to faith, obedience, and transformation—Christians illustrate that their hearts are aligned with God's kingdom rather than the transient pleasures of this world, as affirmed in 1 John 2:17, where it is promised that those who do the will of God abide forever.
