I think this is a topic that needs to be discussed in all churches. Pastors need to be informed and they should be informing their congregations about this development in the world. People are getting a chip in their hands that allows them to pay for things and navigate the world. I'm not going to come out and say definitely that this is the Mark of the Beast, but I know that this is absolutely the inception of such.
There is no reason to think such technology will be sequestered to Sweden and that this is just an isolated incidence that will not proliferate. This is merely a big step in new financial technology that will be promoted globally in the not too distant future. Please discuss this topic at your group meetings and within your greater congregations, especially your church leaders. The discussion can be as simple as:
1) "Did you hear what happened in Sweden?"
Response: Yes/No
2) "Approximately 3500 people got a chip in their hand that allows them to pay for things..."
If they've read Revelation at all, specifically Revelation 13:16-17, a conversation over this dire important topic should easily be had.
P.S. Merry Christmas
