This whole article is a great big waste of paper. Comparing it to a race? Usually, a race has a finish line. Changing the finish line is as much cheating as it would be for me to take a car to drive to the finish line in a real marathon. Once I reach the finish line, they are cheating if they move it farther ahead. And they moved the finish line ahead so many times--1874 was the original finish line, and if they can push that further ahead and get away with it, then I should be able to drive a car instead of running in the race.
What this does is prepares people to run a 100 meter sprint instead of a race that is going to last their whole lives. Real long distance runners and racers know when to slow down during long races. You look at a marathon--even the best runners have been known to slow down, even walking at times, and take quick breaks when needed. You cannot do that with a short sprint, because you would quickly lose the race before you regained speed. If you try to sprint the whole marathon, you are going to bonk. If you slow down to a sustainable pace so you can finish, the witlesses ridicule you for "slowing down".
And for what? The witlesses run an endless "race", with no real prize. The whole "everlasting life" prize is nothing more than a scam. It takes them away from real life. Most witlesses that stay active until the end have virtually no life outside the religion. They live miserable lives, they know nothing about anything except the religion, and they do nothing worthwhile. They end up getting old and stagnant, destitute, and often before their time. In the end, they are accused of "slowing down" when they are capable of going no farther. Some prize that is.
