This is only my vague interpretation from what I know so far. And please understand that I have limited knowledge as of this time.

The time will come when we will no longer have the choice to hate and be at odds with other humans. It is anticipated that we will NEED to love and share in order to survive. It has little to do with beliefs or philosophies but simple survival. We will know that our survival and the survival of our planet will depend upon our cooperation as a species and our interdependence.

This is the main thread of it. It's pretty simple.
