"This event loses more ad more credibility as each year passes, I wonder how much longer it can be believed?"
For those that never saw the event, the event never had any significance to begin with. For those that believe the event occurred based on a teaching without any proof of the event can stop believing for any reason at any time For those convinced that the event did occur in 1914 do not need any more evidence to be convinced, or to make the event any more of a fact. They know. The problem for these later ones is what they concluded from the evidence that they saw and see. They concluded that they would be in a paradise earth in a couple of years and that ain't happening. The Jews did not need to see any more manna coming down from heaven or Moses hitting any more rocks to give them water, they saw that all of the time. They wanted relief.The people that experienced the evidence from Jesus signs did not need to see any more to believe, they were convinced but they still needed to know " when will these things be" and they still got their heads chopped off and killed and died like everybody else (yet even as they were dying, they knew what they knew to be a fact.) The churches that Jesus spoke to recorded in the book of Revelation also had all the evidence to know that the events were facts and they were still getting into trouble -because it is not about evidence Once again, it is not about credibility, it is about relief, the realization of the reward. That is why people loose faith.
