"You are the salt of the earth" IS NOT IN THE ORIGINAL TEXT!

[Andrewn]

You quoted 1 Peter 1:23 which includes the phrase "eis ton aiona./unto the aion" Some people argue that aion does not mean "eternity" but really means "age."

The noun "αἰών" means "age."

1Pe 1:23 (Literal Standard Version)
being begotten again, not out of corruptible seed, but incorruptible, through a word of God—living and remaining—throughout the age;

2Ti 4:10 (Literal Standard Version)
for Demas forsook me, having loved the present age, and went on to Thessalonica, Crescens to Galatia, Titus to Dalmatia;

It doesn't make any sense to translate "the present eternity!"

The Greek word for "eternity" is "αιωνιότητα."

The noun "aion" means "age."
1Pe 1:23 (Literal Standard Version)
being begotten again, not out of corruptible seed, but incorruptible, through a word of God—living and remaining—throughout the age;
2Ti 4:10 (Literal Standard Version)
for Demas forsook me, having loved the present age, and went on to Thessalonica, Crescens to Galatia, Titus to Dalmatia;
It doesn't make any sense to translate, "the present eternity!"

It appears you ignored my explanation. If the "seed" that God provides lasts only a limited [aion] age, then it is NOT incorruptible the person perishes. Jesus said it was incorruptible that means forever i.e. eternity shall not perish.
You are aware that words are often used figuratively in the Bible, aren't you? For example, Simon was not literally a stone when Jesus called him Petros which means stone. James and John were not literally sons of thunder when Jesus called them that. Herod was not literally a fox when Jesus called him that. Peter was not literally the devil when Jesus called him Satan. All figurative. A few figurative uses does not change the inherent meaning of a word.
In ten vss Jesus described/defined "aionios" as eternal, everlasting, forever. In John 10:28 Jesus also defines/describes "aion" as eternity.

John 10:28​

(28) I give them eternal [αιωνιον/aionion] life, and they shall never [εἰς τòν αἰῶνα/eis ton aiona][lit. unto eternity] perish; no one will snatch them out of my hand. ​

In this verse Jesus parallels “aiona” with “[not] snatch them out of my hand.” If “aiona” means “age(s), a finite period,” “age(s) is not the opposite of “[not] snatch them out of my hand’” “Aionios life” by definition here means “eternal life.”
…..In the following verses Jesus defines/describes “aionios” as “eternal/for ever/everlasting” by juxtaposition with other adjective/descriptive phrases.

John 3:15​

(15) That whosoever believeth in him should not perish, but have eternal [aionion] life.​

John 3:16​

(16) For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting [aionion] life. ​

In these two verses Jesus parallels “aionion life” with “should not perish,” twice! Believers could eventually perish in a finite period, thus by definition “aionion life” means eternal or everlasting life.
In total Jesus described aionios as eternal etc. in 10 vss.
Luke 1:33, John 6:58, John 8:51, John 10:28, John 3:15, John 3:16, John 5:24, John 3:36, John 4:14, John 6:27
.....There are another 10 vss. where other N.T. writers, Paul, Peter and John described/defined "aionios" as eternal etc.
1 Timothy 1:17, 2 Corinthians 4:17-18, 2 Corinthians 5:1, Hebrews 7:24, 1 Peter 1:23, 1 Timothy 6:16, Galatians 6:8, 1 Peter 5:10, Romans 2:7, Luke 1:33, Revelation 14:11, John 10:28, Ephesians 3:21, Romans 1:20, Romans 5:21, Romans 16:26

It appears you ignored my explanation. If the "seed" that God provides lasts only a limited [aion] age, then it is NOT incorruptible the person perishes. Jesus said it was incorruptible that means forever i.e. eternity shall not perish.

I agree with this. On further study, the expression "εἰς τὸν αἰῶνα" which literally would be "to the age" actually means "forever." The prepositions "to" and "until" do not necessarily indicate that the action stops at the end of the specified period.

Mat 1:25
but kept her a virgin until she gave birth to a Son; and he named Him Jesus.

In ten vss Jesus described/defined "aionios" as eternal,

Certainly the examples you gave make the point. But I understand aionion/eternal to mean "in eternity" or "in the world to come," as suggested by some scholars, rather than "everlasting/forever." IOW, it refers to a timeless state or place rather than to unending time. I don't see anything in these verses to change my mind.

Here is the full definition of aionios from Bauer, Danker, Arndt, Gingrich Geek lexicon which represents 120-160 years of combined scholarship. Please note the 80+ historical sources which the scholars relied on to determine the correct definition.

I will review these verses. I'm open to learning, perhaps they will change my mind.

Thank you for disagreeing without being disagreeable. You mentioned "scholars". The contradicting opinions of scholars without any supporting credible, verifiable, historical, grammatical. lexical etc. evidence is no more compelling than the scribbling on a public facility wall. See e.g. the definition of aionios above. You may note I did not quote or refer to any scholars except for the 4 who published BDAG. BDAG cites 80+ sources which the scholars consulted to determine the correct definition. For one to argue against BDAG they would have to review more than half the sources and show how the scholars were wrong, that includes so-called scholars. To my knowledge that has never been done.
As I show in my post Jesus said three times that "aionios zoe"/"eternal life" means "shall not perish." That is about as close to unending time that I can think of.
ETA: I searched BDAG and could not find the word αιωνιότητα/aioniote'ta anywehere.
