I'm one of Jehovah's Witnesses.
Tadaa it all makes sense now.
I'm very content with my religion. It's a very active one, so it takes up quite a lot of time. But that's really worth it, it keeps us awake and we really learn a lot about the bible and the coming Kingdom on earth.
As you can see, we are quite normal people. We even post on gaming forums!
Why do we visit you at home? Because Jesus tells us to do so in the bible. We don't earn money with it. Today, the work is totally paid by voluntary gifts. We personally don't keep the money you'd give us, it's used to finance the printing of the reading matter and stuff.
We believe we can save lives with this work.
Like most religions, we truly believe it's the right one.
A thing I like about my religion, is that we have 'family' everywhere. Last year I moved to another town for university, and right away I had really good friends.
