Jerry Hicks Cancer not unlike Jane Roberts Illness
If Jerry Hicks does indeed have cancer, this is not unlike the situation with Jane Roberts who channeled Seth.
Although Seth gave Jane Roberts advice regarding ways she could improve her health, her illness ended up prematurely taking her life. This is no way reflects upon the Seth material itself...teachings that for many have passed the test of time with flying colors.
Clearly, knowing about the law of attraction, beliefs and about how we each create our own reality, does not necessarily translate into complete and total mastery of intentional manifestation...not to mention, as you say, we can't know what's in someone elses vibration.
I personally don't see how a human beings inability to fully practice the advice given in a channeled message has anything to do with the validity of the message itself. I agree completely with your summation on Jerry Hicks Cancer and how this in no way reflects on the validity of the Teachings of Abraham or the integrity of Jerry of Esther Hicks.
The online critics seem to be saying also that since Jerry and Esther Hicks don't seem interested in sharing all aspects of Jerry Hicks cancer with the public, that they are therefore obviously guilty of perpetrating a scam. This is ridiculous.
Jerry and Esther Hicks are human beings and as such, will be having their own personal responses to Jerry Hicks Cancer and all that it likely entails.
I imagine that in due time, Esther/Abraham will comment on this issue, but its extremely unfair for anyone to use the silence surrounding Jerry Hicks Cancer (or we should say, alleged cancer) to tear apart the entirety of the Abraham-Hicks teachings.
If a yoga teacher pulls a muscle and cannot perfectly perform each pose that she teaches, does that mean that the entirety of all that she's taught has been rendered fraudulent? I don't think so. It is the same with this issue about Jerry Hicks Cancer.
Simply because Jerry might fall out of the vortex at times like any normal human, (and even this is a speculation) does not mean that the message within the teachings of Abraham is wrong, false or fraudulent...like you say in your article, it just means that Jerry Hicks is human.
