Show us in detail where you get that idea, it just isn't there. And I repeat, it was scripture where Jesus told the disciples some things that they needed to do and not do when spreading the gospel...nothing more. He didn't ell them to not take money for the reason you say because their money could have been spent, it was for another reason, but whatever it was, it had nothing to do with a prophecy.
It appears some hotshot preacher or whoever, attached that somehow to a future cashless society when it doesn't even come close to being connected to that.
Next thing we know we're calling the dude that made that up, a prophet and start hanging on his every word, when in reality, he's just someone who makes things up/twists the word of God....how dangerous could that be?
And those that pass that type thing along to others are certainly guilty of changing the word of God as well, something I don't think some of us take nearly seriously enough, when we know the penalty for that.
We all, including myself, need to be more careful.
