A Necessary Evil?

We've all heard money referred to as a "necessary evil!"  Nobody ever admits to loving it, yet Scripture clearly says it is the love of money that is the root of all evil.  It doesn't say eating the forbidden fruit, or telling your husband to sleep with your slave girl; It says the "love of money!"  With that fact established, the next point to ponder is the concept of a necessary evil.  Is evil ever necessary?

The reason I ask this question, is the desensitization that can come from equating evil or pain with being necessary.  I remember when "medicine had to taste bad to be good."  And now nobody likes Obamacare . . . I don't know of a child who hasn't attempted to hide under office furniture to avoid a vaccination.  Now look at the reports!  The continual programming and desensitizing has resulted in many negative returns and damage that cannot be undone.

YHWH has created within each of us a way to make a life, make a living, and the ability to negotiate trades.  It is the steadfast prayer of this author that those of the kingdom would step on in to the kingdom economy.  Just like the coming cashless society, the kingdom economy doesn't run on money, HOWEVER; unlike the coming cashless society, the currency of heaven's kingdom is time and talents.

Since buying and selling is referenced for the mark, will the term "it's a necesary evil" be used to justify and rationalize?

And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.  Rev. 13:16,17
