Some of the masses find it hard to accept new ways and new things, but Revelation 21:5 is something to remember.
"And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful."
Technology is intrinsic to the New Kingdom, anyone that says otherwise is kidding themselves.
Technology created mankind and technology we have today is a gift from the heavens. The world wide web was even prophesied by the Hopi.
Advancement in technology is progression and immature souls have been placed on Earth to grow and progress... we have seen a glimpse of what will be in the New Kingdom with some of the technology we have today... and the New Kingdom is the next step in progression.
Contrary to some new age beliefs, the New Kingdom is not some magical fairy land, with hugs and kisses being the main source of what they think life there might be like. When Earth gains heaven status and the Lord takes his throne, a physical effort is still required by all serving the Crown, and by all citizens.
A monetary system is also required for a Kingdom to flourish. Money can be used as a means of incentive to motivate a person for what will be the greater good of society. Money is not evil, but like all things, when in the wrong hands it can be used by bad people for the purpose of evil. This is why Judgment is necessary... as bad people will not make it to the New Kingdom, only the worthy will.
The next logical step in progression of a monetary system is the above mentioned (original post)... a digital currency backed by gold that eradicates the opportunity to unfairly exploit it.
