About the mark of the beast:
Rev13:17
the no 6 is "of man" - re:doctrine/teaching/conscience
1st 6 - man made doctrine revolving around matters of material substance(abstinance as according to 1Tim4
2nd 6 - man made doctrine around perversion of intersexual relationships causing fornication by hypocritical use of abstinance
3rd 6 - man made doctrine that perverts God's freely given stewardship of all fruits of the earth and knowledgability
the phrase "on the right hand" directly and absolutely means THE WORKS OF ONES HANDS having the conscience of these three man made doctrines.
"on the forehead" literally means IN THE MIND AND THINKING OR BELIEF OF ONE containing the directives and what is known as the ABOMINATION OF DESOLATION of which Jesus spoke of when he mentioned these times we are living in.
About "buying and selling":
When you look what is called the "transact" you see two things, a giving and a recieving.
The bible has it written and revealed to us, that "Giving is more blessed than receiving" in that "AS EVERYONE IS GIVING, ALL ARE RECEIVING".
The spirit of the world tries to perpetuate a FEAR of "non reception" that truly is A FIGMENT OF ANY'S IMAGINATION.
hence why also the bible reveals to us THE PURPOSE OF BEING even in the, or ANY SENSE OF HAVING sating (2Cor8:14)-"your abundance is a supply for their lack and their abundance is a supply for your lack"
This means that THERE IS NO FEAR IN "SEEKING TO GIVE", and "THERE IS NO HOPE without people(made in Gods Image) seeking to give".
The world, (babylon that harlot city-Rev17/18/19) simply tries to IMPLY(fearfully) tht there may seem to be some sort of restriction in any reception or giving, which is IMPOSSIBLE for anything to function EVEN FOR THE HYPOCRICY of the transact of which it politicalt FEEDS on giving and receiving.
The world's spirit of mammon tries to constrain one from any other kind of action or doings tht reffer to STRICTLY GIVING.
The fear attempts to operate against anyone receiving anything.
I.e.
Freely giving (1)
Giving having something to receive as well(2)
Receiving and having something to give(3)
Freely receiving(4)
The world tries to say:
-(1)-->>(only2&3only)<<--(4)-
HAVIN (2&3) as a POLICY and "norm"
The REALITY and WHAT GOD HAS SET AS STANDARD:
--(1)--(2)--(3)---(4)---
All together are norm begining with Jesus Saying "IT IS MORE BLESSED TO >>GIVE<< THAN RECEIVE"
For worldly refference of knowledge, there is such known as "Modern Money Mechanics", a documentation of the IMF given as to the basic fundamentals of "Reserve Banking" of which ALL is entirely based on the value of scarcity(inadequacy).
Anything getting a value from NOT BEING THERE or ANY GETTINGS OF VALUE FROM 'NON EXISTENCE' is blasphemouse hypocricy to any reality of identification for whatsoever said value is applied.
true stewardship and its across the board application of wisdom is given in 2 Corinthians 8:14 (your abundance is a supply for their lack and their abundance is a supply for your lack).
The immense destruction, invalidity and construct of the community confusion and desolate chaos from the conscience of scarcity is apparent across the face of the earth as we know it just as is written in the book of revelation about the fall of this ancient evil.
Gods word is sound towards the redemption of all mankind in His giving of His Son both in death and especially resurrection FOR ALL so that all come to repentance and HAVING OF ETERNAL LIFE IN HIM.
