Just one issue with it though.
At around the 7:35-7:38 time marks on this video he states that he has told millions then probably billions of people about the generation that wouldn't pass away.
There are very few people on this earth that have ever reached a billion people with any message (or even songs etc)
If he gave talks in every Kingdom Hall in the world and spoke at every Assembly/Convention, the most he would reach would be between maybe 7-14 million people.
Then add in every single person he could have possibly talked to in field service and I can grant you it would fall far short of the one Billion mark, much less Billions.
I think he got caught up in it and said billions by mistake but the rest of what I heard in the video sounded spot on and would like to say thanks for posting it and sharing your experience(s).
