1 John 2:15-16 reads, “Do not love the world or the things 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 sin nature] and the desires of the eyes [which relates to the warped perspective we sometimes have] and pride in possessions—is not from the Father but is from the world.”
