Cold Steel, you are talking about something completely different than the rest of the posters on this thread. The majority of posters here are talking about a fictional event that the WT promises and the rank and file JWs look forward to. You are talking about a fictional event that the Bible talks about and that you look forward to. Totally different things.
But as SBF rightly says, JWs are growing faster than the population.
More correct would be to say that the JW's rate of growth is greater than that of the population, which isn't relevant. In real numbers, there are far, far, FAR more "worldly" people born each year than convert or are born into the JW religion. The number of babies born is nearly 1000 TIMES greater than the number of increase in the JWs annually.
