In context
15Do not love the world or anything in the world. If anyone loves the world, the love of the Father is not in him. 16For 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. 17The world is passing away, along with its desires; but whoever does the will of God remains forever.
