What are the prophecies that predict a golden age?

This page expands on a number of prophecies and visions, some contemporary, some centuries old, which state that there will be a third age of humanity, a time when we will live together in peace and love. But the transition from the current second age will be a time of great suffering as our civilization is destroyed, billions die, and those who remain are forced into lives of pure, desperate survival. However, the suffering will not be just suffering. It will be the necessary crucible in which the future human is formed.
