I am really amazed that anyone is amazed that Jerry Hicks died. Folks, he was in his eighties. "Eighty-Year-Old Dies of Cancer" .... Folks, does that really strike you as headline news? Even the Buddha died, even Jesus died, and Sai Baba, the modern miracle-maker of our times, died this year.
Firstly, while all things are possible with the Law of Attraction (and indeed, all things that exist come into existence because of the Law of Attraction), this does not mean that you can do all things. It only means that you can do all things, to the extent that you are able to control and shape your thoughts and beliefs about them.
The belief in death is very deep-rooted. Do you think it is easy to uproot this belief? It is not easy, even if your wife happens to be a channeller.
Secondly, if you have listened to Abraham teachings about what death is all about, and if you believe in those teachings, you will see that death is not a scary thing, it isn't feared and avoided at all costs. You live your life here on planet earth; you do your best to make it a good one; and when the time comes, you go on to play somewhere else.
If you can accept that death isn't scary, that death is just a door to another kind of life, then do you see? When you are quite old and lying there on a hospital bed and feeling quite ill, maybe you may well decide that you're going to quit the "fight" and just go to the next better place.
