So according to the most pessimistic calculations (which, surprisingly enough, were presented by me) we only have ~1½ years left before the **** is going to hit the fan.
The question is: what should we exactly do? Pray a lot and hope for the best? Stock up toilet paper for 7 years? I'm clueless upon things of this magnitude. I'm only able to deal with tragedies like a loss of job, a break-up etc... but this is a bit too much. I really do not know.
May God help us. 
Well, on Thursday I was scanning the paper for spiritual meetings in my area. I found there's an event called "From Broken To Whole" at certain prayer house. It was in the opposite end of the city (iow. about an hour away), but as I found the theme interesting, I decided to go anyway.
After some hymns and Bible reading it was the time for prayer. I requested prayer and told I'm feeling very uncertain about the future, and that I'd like to receive some wisdom on how to go about things. So, a woman laid her hands on me and started praying. I was extremely surprised at the things she said. She saw two visions about me with her spiritual eyes. In the first one I was carrying a torch and marching. A lot of people were following me. I was going forward (possibly leading people into a battle) with braveness and determinaton, without any fear. In the second one she saw me as a small child, sitting on the floor surrounded by unopened presents. Then I started opening the presents one by one. I was being extremely delighted, as I was receiving the kind of presents I thought I'd never get. The intercessor explained the presents were spiritual gifts. Then she said she sensed I should read about Gideon in Judges (very unsure of himself, lesser tribe of Manasseh, weakest clan in tribe, least in father's house, but chosen to deliver Israel), for my situation was very similar to his. She said I'm going to have a big role in God's future plans and that God is going to change my life in a totally unimaginable way.
Like I said, I was very surprised at what I heard. My initial thoughts were something like: "well... Father, I'm flattered and all, but I'm not sure about this whole torchbearer thing. How I'm supposed to pull it off? How about if I just continue playing bass guitar in the worship band, and you go find someone more competent for the job?" As if the intercessor had read my mind, she continued with "You're not going to pull it off. Not on your own. But with God, everything is possible. God is going to do it through you."
I left the place feeling greatly relieved. All this "end of the eon" stuff still concerns me, but now at least I believe I'm in good hands.
