Is there any way the world can live in peace?

In October 1985 the Universal House of Justice at the Bahá'í World Centre issued a statement to The Peoples of the World that can answer this question. The statement is entitled The Promise of World Peace. Here is an extract:

"... The Bahá'í Faith regards the current world confusion and calamitous condition in human affairs as a natural phase in an organic process leading ultimately and irresistibly to the unification of the human race in a single social order whose boundaries are those of the planet. The human race, as a distinct, organic unit, has passed through evolutionary stages analogous to the stages of infancy and childhood in the lives of its individual members, and is now in the culminating period of its turbulent adolescence approaching its long-awaited coming of age.

A candid acknowledgement that prejudice, war and exploitation have been the expression of immature stages in a vast historical process and that the human race is today experiencing the unavoidable tumult which marks its collective coming of age is not a reason for despair but a prerequisite to undertaking the stupendous enterprise of building a peaceful world. That such an enterprise is possible, that the necessary constructive forces do exist, that unifying social structures can be erected, is the theme we urge you to examine.

Whatever suffering and turmoil the years immediately ahead may hold, however dark the immediate circumstances, the Bahá'í community believes that humanity can confront this supreme trial with confidence in its ultimate outcome. Far from signalizing the end of civilization, the convulsive changes towards which humanity is being ever more rapidly impelled will serve to release the "potentialities inherent in the station of man" and reveal "the full measure of his destiny on earth, the innate excellence of his reality".
