That's one way to look at it. Why is it so hard to see that the word of God is not concerned with the political nations of this world and the buying and selling has to do with the gospel not worldly goods?
Proverbs 23:23 Buy the truth, and sell it not; also wisdom, and instruction, and understanding.
When Christ comes on the last day it will be like a thief in the night. It will be business as usual .If there is to be a famine it will be for the hearing of the gospel. Christ begged the question in Luke.... when he comes will he find faith in respect to the Holy unseen place of God revealed by His written law or men walking after the temporal, seen in the imaginations of their hard hearts ?
Knowing we are not that which we will be I would think according to the descriptor based on 2 Corinthians 4:18 it indicates something that is spiritual .
The mark or seal can represent a person that has no faith (atheist) and therefore no rest coming from the sacrifice of the lamb of God slain from before the foundation of the world. Just as below(
Ezekiel 9:3-5) it can be used to identify the generation of Christ the spiritual unseen seed.
Ezekiel 9:3-5 King James Version (KJV) And the glory of the God of Israel was gone up from the cherub, whereupon he was, to the threshold of the house. And he called to the man clothed with linen, which had the writer's inkhorn by his side;And the Lord said unto him, Go through the midst of the city, through the midst of Jerusalem, and
set a mark upon the foreheads of the men
that sigh and that cry for all the abominations that be done in the midst thereof.And to
the others he said in mine hearing, Go ye after him through the city, and smite: let not your eye spare,
neither have ye pity:
The 666 mark works the same way as describing those whos appose the gospel. The generation of men.
Six is the day God created mankind from the dust of the field as the generation of Adam natural man .
Six hundred and sixty six represents dust as innumerable or every human he created and breathed in the temporal spirit of life.
God forbids the numbering of His people. He desires we walk by faith the unseen; "His Holy Place".
No exact numbers are ever given in that way. He is our hiding place or city of refuge. People would be quick to fill in the number. Like that of the Jehovah Witnesses that number their special ones under the number 144,000...... ran out years later. 144,000 is a number that represents the generation of Christ, a called out generation His eternal chaste virgin bride .
I would offer numbers are to be used as metaphor words in parables to give the gospel the spiritual understanding of our father in heaven... hiding it from those who add or take away from His book of law, the Bible. .
Six hundred and sixty six represents natural unconverted man as a restless wanderer like Cain. Esau another marked man who sold his spiritual birth rite to Jacob for a cup of soup. Seeing not value in the spiritual unseen... just as Cain whose punishment (no sabbath rest) was more than he could bear. .
Genesis 13:16 And I will make thy seed as the dust of the earth: so that
if a man
can number the dust of the earth,
then shall thy seed also be numbered.
666 represents temporal seed as dust that cannot be numbered "the flesh as that seen" the generation of Adam and not the spiritual unseen Spirit of Christ as the generation of Christ (believers) 144,000 .
Revelation 13:18 Here is wisdom. Let him that hath understanding count the
number of the beast: for
it is the
number of a
man; and his
number is
Six hundred threescore and six.
It
is the number of man.
Six hundred threescore and six would appear to represent the innumerable. It is the number of natural unconverted man. It would seem either buy that truth or sell it .
