I guess we are lucky that we have the opportunity to see these other gospels now.
As to what Jesus said about loving ones neighbour being tied to having eternal life, I would tend to agree with that through this line of reasoning.
Now I figure that there is a balance on the planet and in general energy gets shifted around rather than disappearing because if it always just disappeared then slowly the world would just evaporate and since it hasn't done that, well there must be a general system of conservation.
Even with something like the hole in the ozone layer - the space that was ozone has just become something else - things transform. And yeah, you could stretch this outside the planet to the universe as well I would suppose - but for simplicity of argument lets assume that things recycle on the planet.
What happens to our flesh - well that gets turned into dirt basically, pushing up daisies and what not. That is tangible and we can see that process. However, I'm inclined to think that there is also a level of energy associated with the human body that does not decay.
I say this because I think of scientific evidence of the ability to do things like remote viewing, which involves telepathically connected to the mind of another person and drawing what they are looking at. A couple of physicists did these experiments at Stanford University, under rigorous controlled experiments and the results were very convincing.
Then there have been my own experiences, were I was successful in just directing my thoughts to a couple of people, putting a suggestion in their mind that they followed through on (without any words being said and quite particular requests that were completely filled), dreams that ended up connecting to real places and numbers of relevance to persons in my dreams and also the odd occasion of astral travelling, where you find yourself walking around your house at night, seeing everything clearly, then starting to wonder why you are there, realizing you've left your body and snapping back into it quick smart with a start. That is a really weird sensation - one minute you are moving about and the next, when back into the body, you are locked in it and it takes a bit of effort to get it to move and wake up. Not an experience I can say I am fond of.
Now you might think - astral travelling, what rubbish? But actually, a lot of stories, particularly by people who had near death experiences or floated up out of their bodies on the operating table and watched what was going on and told the doctors what they saw the doctors doing afterwards (in a manner like there was NO WAY the patient could have seen what they saw). I remember one such story about this, where someone was being operated on and they ended up outside of the building but quite a few floors up and they saw a shoe sitting on a ledge - a ledge I might add that was nowhere near where they had been in the hospital and obviously quite unnoticed by people in general. When the hospital staff went to check it out - there was the blimmin' shoe.
So yeah, I do think there is an energy inside of our bodies that we can actually direct beyond the bounds of our bodies, which clearly says to me that it is something more than body matter that decomposes, it is a different kind of energy and my guess is that this energy gets recycled, I don't know whether just into other humans, whether in whole or in part, basically I don't know HOW it is recycled but I do think it is perpetual and in that sense has an immortality that our body lacks.
So I guess the thing to learn from what Jesus said is to love your fellow man because you might die tomorrow and some part of you becomes part of his child born 9 months later, or some such. What I am trying to get at is that we've all got to share this energy, this immortality is possessed by us collectively, so if we shit on the next person in a sense we are shitting on ourselves and perhaps putting our own immortality at risk (you know, like we end all exterminating each other and then there is nowhere for our energy to go).
Actually, thinking on it a bit more, it must be that this type of energy doesn't just come from humans but all manner of things that have life. That is because our population keeps growing while other living things die off, so we must be consuming their animation.
