Hypocrites, They not only block themselves from the kingdom of heaven but block off others too.
Whats so silly is that 1. They took the 144,000 number literally in the first place. It was probably a hatred of Christendom that made them think that only a few would make it (themselves, of course). And 2., that once their numbers were growing and they were reaching 100,000, they thought, whoops! Let's invent another class of people here who aren't going to heaven. Let's hype up the paradise so some will find it appealing before making the announcement.
Pretty similar to what they've done with the interpretation of 'generation' in the last few decades. Conveniently receiving 'new light' just before things get too far along. Seriously, what a joke of a religion.
