This video...it's really pretty funny that they made it. Basically, it's the video that the pastor in the story "Left Behind" creates and leaves in his office for years until he vanishes in the Rapture; it is then found by Bruce (the assistant pastor who was left behind because he didn't actually trust God, even though everyone else thought he was very devout)...the video talks about how they knew what was going to happen, how to prepare for the next steps of the end-times, and how to follow God's plan after all; it's not too late.
Basically, this is a good video (if agree with the Left Behind authors' interpretation of end-time prophesies) to keep on your shelf so that you can let people know what happened to you after it's happened, whether it's in 2 hours or 40 years (Concerning the hour, no man will know except for the Father).
I definitely recommend the book "Are we Living in the End Times?" to explore their viewpoint and hear their take on the prophecies that have been fulfilled already and indisputable and what will be happening in the future (they discuss each view on the Rapture/Tribulation/Second Coming, and the scriptural basis for each, but also why they feel strongly that the interpretation they have is right. It also explains which characters/events from their Left Behind series are entirely fictional and which are based on scripture, and gives an in-depth look at it. A good book to read whichever viewpoint you have as an overview to them all. If you find that you agree with their interpretation, then you may want to get this video to have around the house or church in preparation for the second coming and to explain what happened to those left behind.
