Easy to say. Another thing to prove. Can you prove the "aionion" fire (Jude 1:7) that burned Sodom burned forever? Is Sodom still burning? If that fire was temporary & not "eternal", why must the use of the same words, aionion fire, in Matthew 18:8 & 25:41 mean the fire is "eternal"? Is Love Omnipotent an eternal sadist infinitely worse than what Satan, Hitler & Stalin have done combined?
By that logic one day Jesus being with the disciples "will one day expire", since Jesus said:
teaching them to observe all things, whatever I commanded you. And behold, I am with you all the days, until the completion of the age. (Mt.28:20)
You have merely asserted that, but provided no evidence, argument, reasoning or proof that what you allege is true and not false.
No. Is Jesus being with us only temporary since He said:
teaching them to observe all things, whatever I commanded you. And behold, I am with you all the days, until the completion of the age. (Mt.28:20)
How much more will the blood of the Annointed, who through a Spirit of That Age* offered himself unblemished to God, purify our conscience from dead observances, for worship of a living God! (Heb.9:14, DBH, * "An aeonian Spirit.")
Through the Spirit of that age, e.g. the Holy Spirit that will reign in the millennial age of 1000 years, or the Holy Spirit of this present age, Jesus "offered himself". Does that mean this present age or the millennial age will last forever? No. Does that mean the Holy Spirit will die when those ages end? No. No more than Jesus' words in Mt.28:20 mean He will only be with His disciples in this age & not after this age.
Is Jesus being with His disciples temporary since He said:
teaching them to observe all things, whatever I commanded you. And behold, I am with you all the days, until the completion of the age. (Mt.28:20)
And having been perfected he became a cause of salvation in the Age for all who are obedient to Him (Heb.5:9, DBH).
"salvation in the Age", e.g. the millennial age kingdom. Those who are not "obedient to Him" will not partake of that salvation. Does that limit salvation to only the millennium age? No, for the saved will also have immortality, incorruption, always be with the Lord, pain will be no more, etc (Lk.20:36; Rev.21:4; 7:14-17; 1 Cor.15:42-57, 1 Thess.4:17, etc). Eventually all will have salvation that never ends, for God will be "all in all" (1 Cor.15:22-28; Rom.5:18-19; Phil.2:9-11; etc).
Not by blood of goats and calves, but by his own blood, he entered once and for all into the Holy of Holies, having obtained an emancipation payment for the Age (Heb.9:12, DBH).
Those that obey Him (Heb.5:9) obtain redemption in "the Age" (Heb.9:12). Those that don't obey Him will not, though even they will be eventually saved along with the saints, as referenced above.
The same words, aionios kingdom, are used of Satan's kingdom. Are you going to argue that Satan's aionios kingdom is "eternal"? Early church father Chrysostom wrote that Satan's aionios kingdom will end:
"For that his[Satan's] kingdom is of this age,[αἰώνιος] i.e., will cease with the present age[αιώνι] ..." (Homily 4 on Ephesians, Chapter II. Verses 1-3).

Will Christ's aionios kingdom of the millennial aion (=eon/age) last forever? Obviously not.
Blessed and holy is the one who has a part in the first resurrection; over these the second death has no power, but they will be priests of God and of Christ and will reign with Him for a thousand years. (Rev.20:6)
For thus the entrance into our Lord and savior Jesus the Annointed's Kingdom in the Age shall be lavishly provided you (2 Peter 1:11, DBH).
And they came to life and reigned with Christ for a thousand years. (Rev.20:4b)
Does that mean they only live for 1000 years & their life is temporary? Does that mean they reign only for 1000 years and their reign is temporary?
to whom the honor and might of the Age; amen (1 Tim.6:16b, DBH)
The power of Jesus in the millennial Age no more denies His power after that age or in this present age than your teenage years deny your adult years. Just because your teenage years ended, that doesn't mean you ended. That God is the God of Abraham or Israel does not deny that He is the God of all the earth. To say that God is the Sovereign God of this present wicked age does not mean He is temporarily God or will cease to be God after this present eon ends.
God's glory of that Age. Same idea as 1 Tim.6:16 above.
Now we know that, if the tent that is our earthly home is destroyed, we have a building from God, a home of the Age, in the heavens, not made by hands. (2 Cor.5:1, DBH*).
Paul already told the Corinthians, in his first epistle to them, that the resurrected body will be "immortal" & "incorruptible" (1 Cor.15). To repeat that again in 2 Cor.5:1 would be redundant.
The "heavens" (2 Cor.5:1) are not eternal, but will pass away. So why assume that "the Age" (2 Cor.5:1) is eternal? After the millennial Age ends the heavens will pass away (Rev.20). That doesn't mean the immortal body will pass away. Obviously it cannot.

More examples of aionios as a finite duration in Koine Greek:
Two Questions
Does aionios always mean eternal in ancient Koine Greek? (paradise, Gospel, hell) - Christianity - - City-Data Forum
If Jesus wished to express endless punishment, then He would have used expressions such as "endless", "no end" & "never be saved" as per:
How Scripture expresses endless duration (not aion/ios) (paradise, hell, punishment) - Christianity - - City-Data Forum
Jesus didn't use the best words & expressions to describe endlessness in regards to punishment, because He didn't believe in endless punishment.
ENDLESSNESS not applied to eschatological PUNISHMENT in Scripture:
could an 'eternal punishment' simply mean that once instituted it will not change?
