'Of the World' in the Bible

They [who teach twisted doctrine] are of the world and belong to it; therefore they speak from the [viewpoint of the] world [with its immoral freedom and baseless theories—demanding compliance with their opinions and ridiculing the values of the upright], and the [gullible one of the] world listens closely and pays attention to them.

We [who were with Him in person] have seen and testify [as eye-witnesses] that the Father has sent the Son to be the Savior of the world.
