1 John 2:15-17 CJB says, “Do not love the world or the things of the world. If someone loves the world, then love for the Father is not in him; because all the things of the world – the desires of the old nature, the desires of the eyes, and the pretensions of life – are not from the Father but from the world. And the world is passing away, along with its desires. But whoever does God’s will remains forever.”
In this passage, the term “world” is referring to the world system or the ways of Babylon – not people. The phrase “things of the world” is speaking specifically toward the objects and influences that are valued inside this world system. Things that become the idols of men. The Apostle John infers that the act of clinging to the world system is proof that a person is living out of or from their old nature, the sin nature of the flesh. He is admonishing believers to turn away from this pull and commit to our Father in Heaven.
