What if you were fourteen and you found out your father was one of the twelve disciples that's alive now and worse of all he does not remember meeting Christ?
Well for Wendy Wolfson that's the case well in a short version.
It's up to her to find out why he does not remember being a disciple and he may not be the only one alive either.
Heaven High the Bible is alive in modern times, how and why?

It is a unique idea, angelsword. However it could be a bit touchy to write. It would take a lot of research, I'm guessing. But if you could pull it off, it would make a very intriguing and interesting read.

I have that figured out but can not reveal that yet.

There is the disciple that Jesus said would not taste death before the kingdom of heaven came in power. I think it was John. *hopes he didn't botch the verse*

No, you were right:

"This saying therefore went out among the brothers, that this disciple wouldn't die. Yet Jesus didn't say to him that he wouldn't die, but, "If I desire that he stay until I come, what is that to you?" - John 21:23

However Jesus didn't say He definitely wouldn't taste death, but it makes for an intriguing storyline. The book "So You Don't Want to Go to Church Anymore" by Wayne Jacobson has a storyline that vaguely includes a similar idea to this.
