In a passage in which we might not even suspect what the intention of the author really is, the author of Hebrews, says,
“For
he didn’t subject the world to come, whereof we speak, to
angels.”
Heb 2:5 WEB
The word world here is a word for the inhabited world (oikomen?). Of course most of the references to “earth” are of this present earth, with absolutely no doubt as to its meaning.
“God
said, “Let the earth bring forth living creatures after
their kind, …”
Gen 1:24 WEB
Or many other passages.
On others usages we might have to think a while.
Jesus says,
“You
are the salt of the earth, but if the salt has lost its
flavor, with what will it be salted? …”
Mtt 5:13 WEB
It
does seem to speak of this present earth. Also in the very next verse
He says,
“You are the light of the world. A city located
on a hill can’t be hidden.”
Mtt 5:14 WEB
Again it seems to speak of our present world. But then let’s look at an earlier verse.
“Blessed
are the gentle,
For they shall inherit the earth.”
Mtt 5:5
WEB
Now of which earth is Jesus speaking? In one sense it seems to apply to this present world, and passages like,
“For
such as are blessed by him shall inherit the land. Those who are
cursed by him shall be cut off.”
Psa 37:22 WEB
This indicates the wicked have a tendency to die off, and those God favors end up living on. All of which is true in a general sense, however there are many senses in this world when the gentle do NOT seem to inherit everything. And Jesus clearly asserts that this present universe will pass away.
“For
most assuredly, I tell you, until heaven and earth pass away, not
even one smallest letter or one tiny pen stroke shall in any way pass
away from the law, until all things are accomplished.”
Mtt 5:18
WEB
So when you have prophecies of
the “earth”
you may have questions to ask.
Often times the context will clearly give the answer. We clearly know, if we are attuned to Scripture at all, that this present earth will NOT last forever.
“10
And,
“You,
Lord, in the beginning, laid the foundation of the earth.
The
heavens are the works of your hands.
11
They will perish, but you continue.
They all will grow old like
a garment does.
12
As a mantle you will roll them up,
And they will be
changed;
But you are the same.
Your years will not
fail.””
Heb 1:10-12 WEB
So when we have a long passage like Isaiah 24 which talks of the earth being laid waste Isa 24:1, and being polluted Isa 24:5, and then it says,
“The earth shall stagger like a drunken man, and … shall fall, and not rise again.”
Isa 24:20 WEB
Well then we can be pretty sure is speaking the final end of this present earth.
