There is a prophesy in the book of Revalation where the Lamb of God will be attacked but it can't be defeted. The WT believes that since the real Lamb of God can't be seen or reached, It really means that the bros. and sis. in the org. are the ones who will be attacked around the world and they can't get defeted because the true Lamb of God is with them. So perhaps you will see them attacked yet not to end the JWs. After this, the prophesy continues, it is said that all other religions are them going to get attacked and they will be defeted and completely vanquished from existence due to the lies the teach and the hypocracy they allow. Babilon the Great will fall!
To know if this is the true interpitation of this symbolism means we have to wait and see if this is what happens. Besides, it is human tendancy to try to investigate everything that exists around us using common scientific sence, like the examples of discovering new technology, how things work, the show 'Ghost Hunters', etc. Never in our life have we had this much information out on the world as we have now. Thanks w.w.w.
