Welcome to the forum Brother Prince. You have already received valuable information and advice from the others. You can learn much from the experiences of these members and the sites and books they have
recommended. I see that you don't know too much about the history of the world in general. We, the world in general, may be having bad times but conditions in the past have been much worse that what we face
today except for maybe a nuclear war. You need to educate yourself and make your own decisions. Forget about when the end will come. If/when it comes, it comes. My advice is to live for today because that is all you
have. As for what the WBTS has to gain, as the others have stated, Money and Power over these millions of people are great motivators.
