Good news! There is biology and evolution on our side.
Contrary to what conventional science and religion have been telling us, evolution is neither random nor predetermined, but rather an intelligent dance between organism and environment. When conditions are ripe, either through crisis or opportunity, something unpredictable happens to bring the biosphere into a new balance at a higher level of coherence.
While we often perceive of examples of spontaneous remission as miraculous healings that happen by the grace of God, looking a little deeper we see something else at work. Quite often these fortunate individuals actively participate in their own healing by consciously or unconsciously making a key, significant change in their beliefs and behaviors.
So here is the bad news and the good news. The story of human life on Earth is yet to be determined. Spontaneous evolution will depend on whether we humans are willing to make changes in our individual and collective beliefs and behaviors, and whether we are able to make these changes in time.
For millennia, our spiritual teachers have been pointing us in the direction of relatedness and love. Now science is confirming that ancient wisdom. We are each and all cells in the body of an evolving giant super-organism we call humanity. Because humans have free will, we can choose to either rise to that new level of emergence or, in the manner of dinosaurs, fall by the wayside.
Like it or not, our future depends on the choices we make as a species.
