Absolutely!
Each and everyone of the four examples are not relevant to the OP. The context of these are not the same as the context of eternal damnation.
6 I went down to the bottoms of the mountains;
The earth with her bars was about me for ever:
Yet hast thou brought up my life from corruption, O Lord my God.
Had God not brought him up, he would still be there, exactly as is said. God changed this situation.
4 Howbeit the Lord God of Israel chose me before all the house of my father to be king over Israel for ever: for he hath chosen Judah to be the ruler; and of the house of Judah, the house of my father; and among the sons of my father he liked me to make me king over
God chose that David would be King forever, but what did David do to change that?
Not one of these examples change the meaning of forever. One must not "cherry pick" a particular part of a scripture to define it's meaning.
All the questions being talked about can be offered up, but they will not change the meaning of the words being discussed. Not only would it be a waste of time, but a waste of broadband.
Merely speculation for what one wishes to believe, which counters God's being just.
What's good for the goose is not good for the gander?
So you have cleasrly stated that you believe that every single place in English Bible it says "forever, everlasting" that is literally means that!
Yet you did not properly explain those 4 verses, because I have shown that everlasting even meant 40 years.
Another example, Jeremiah predicted that God would kindle a fire in the gates Jerusalem's palaces that would "not be quenched". See Jer 17 :27. This prediction was fulfilled by Babylonian King Nebuchadnezzor when he burnt the palaces of Jerusalem. See Jer 52:12-13. The fires although unquenchable are not still burning today. The results are irreversible, not the process.
This is not to say that the fires of gehenna will not burn for a period of time. The Greek word for "eternal" and "forever" (aionios) denotes a period of time. If Strongs Concordance on the word "ever" is consulted, you will notice that the Greek word means "an age, a period". Under the word "aionios" in the Analyical Greek Lexicon p.11 we have the following words, "a period, era, age. . . indeterminate as to duration." The latter phrase is critical. "Forever" denotes periods of time which are indeterminate and unspecified as to beginning or end.
So when the bible speaks of "eternal fire" it must be understood in the context of all it says on the subject. The fires of Sodom and Jerusalem burnt and it says "eternally" (that is a period), and the period in which it burnt brought about results that were complete in their purpose. Hence the fires of Gehenna will burn for a time and ultimately produce "destruction",that is annihilation. See Matt 10:28 where Jesus says that both soul and body will be destroyed (annihilated, Greek apolummi) in gehenna! The fires will burn until Satan and his followers will be brought to ashes and be no more.
And you didn't explain Edom. Let me show you what it says about Edom:
Isaiah 34:6-11
6 The sword of the LORD is bathed in blood,
it is covered with fat—
the blood of lambs and goats,
fat from the kidneys of rams.
For the LORD has a sacrifice in Bozrah
and a great slaughter in the land of Edom.
7 And the wild oxen will fall with them,
the bull calves and the great bulls.
Their land will be drenched with blood,
and the dust will be soaked with fat.
8 For the LORD has a day of vengeance,
a year of retribution, to uphold Zion’s cause.
9 Edom’s streams will be turned into pitch,
her dust into burning sulfur;
her land will become blazing pitch!
10 It will not be quenched night or day;
its smoke will rise forever.
From generation to generation it will lie desolate;
no one will ever pass through it again.
11 The desert owl and screech owl will possess it;
the great owl and the raven will nest there.
God will stretch out over Edom
the measuring line of chaos
and the plumb line of desolation.
The English Bible clearly says the fires of Edom will not be quenched night or day; its smoke will rise forever. Now you said that definitely evertime Bible says forever that it literally means forever. So how come Eden is not burning today and how come the smoke is not eternally going?
