'World' in the Bible

And when He again brings the firstborn [highest-ranking Son] into the world, He says,“And all the angels of God are to worship Him.”

It was not to angels that God subjected the [inhabited] world of the future [when Christ reigns], about which we are speaking.

For we who believe [that is, we who personally trust and confidently rely on God] enter that rest [so we have His inner peace now because we are confident in our salvation, and assured of His power], just as He has said,“As I swore [an oath] in My wrath,They shall not enter My rest,”[this He said] although His works were completed from the foundation of the world [waiting for all who would believe].

and have tasted and consciously experienced the good word of God and the powers of the age (world) to come,

Now even the first covenant had regulations for divine worship and for the earthly sanctuary.

Otherwise, He would have needed to suffer over and over since the foundation of the world; but now once for all at the consummation of the ages He has appeared and been publicly manifested to put away sin by the sacrifice of Himself.

Therefore, when Christ enters into the world, He says,“Sacrifice and offering You have not desired,But [instead] You have prepared a body for Me [to offer];

(people of whom the world was not worthy), wandering in deserts and mountains and [living in] caves and holes in the ground.
