Can “all be vanity” (literally)?

The Bible states in Ecclesiastes 1:2

“Vanity of vanities, saith the Preacher; vanity of vanities, all is vanity.”

Is it true, “literally”?
Yes!

How?
Because “all” of “all created things” ( = “all things” in short) ain’t gonna last “forever” in the “current state”. Even the heavens and the earth will be made “new”. See these verses which declare this “literally” too:

“and for new heavens and a new earth according to His promise we do wait, in which righteousness doth dwell;” (2 Peter 3:13)

“And I saw a new heaven and a new earth, for the first heaven and the first earth did pass away, and the sea is not any more;” (Revelation 21:1)

“For, lo, I am creating new heavens, and a new earth, And the former things are not remembered, Nor do they ascend on the heart.” (Isaiah 65:17)

Is it true?
God has declared to make “All things New!” in the verse below (which will take place into the “ages to come” – Ephesians 2:7):

“And He who is sitting upon the throne said, ‘Lo, new I make all things; and He saith to me, ‘Write, because these words are true and steadfast;'” (Revelation 21:5)

Really, can we trust His Word?

I repeat, “…And He saith, Write: for these Words are Faithful and True.” (Revelation 21:5)

To Him be the Glory and Dominion into the ages of Ages and beyond!
Blessed God Truly!
