Heathen,
This is their current teaching. From your post I wasn't sure if you thought this was a past teaching or not. They used to teach that Abaddon was satanic or Satan himself and that the locusts were demonic coming up out of the abyss. That is pretty much how most theologians interpret it. Back a while ago, the Watchtower switched their teaching (another complete flip flop) to the opposite and teach that Abaddon is Jesus and that the locusts are JWs.
It's nuts. If you look at the bible and other references to the abyss, nothing good ever comes out of the abyss. The beast is said to come out of the abyss and the demons that Jesus sent into the swine were begging Jesus not to send them to the abyss.
This should just show people how way out the organization is and how they have no clue who Jesus is and they don't have anything else right either. It's like they are throwing a bunch of crap at the wall and seeing what sticks. How can anybody actually trust anything they say?
