There is an interesting website called Endtime Insights found at
http://www.endtimeinsights.com. The pastor's name is Steve Wholberg and I think he gives the most common sense approach to the end times.
The talks about barcodes are rooted in Jesuit Futurism. What pastor Wholberg tries to communicate is that the Bible is not meant to be interpreted literally like some of the right wing conservative christian fundamentalists are doing. The bible is written in metaphor and needs to be treated as such. That's his point on all of this.
