Today, this Servant has assuredly come to vivify the world and to bring into unity all who are on the face of the earth.

That which God willeth shall come to pass and thou shalt see the earth even as the Abha (Most Glorious) Paradise .-- BAHA'U'LLAH, Tablet to the Ra'is.
Conflict versus Concord During the past century scientists have devoted and immense amount of study to the struggle for existence in the plant and animal world, and, amid the perplexities of social life, many have turned for guidance to the principles which have been found to hold good in the lower world of nature.

In this way they have come to regard rivalry and conflict as necessities of life, and the ruthless killing out of the weaker members of society as a legitimate or even necessary means of improving the race.
Baha'u'llah tells us, on the other hand, that, if we wish to ascend the scale of progress, instead of looking backward to the animal world, we must direct our gaze forward and upward, and must take not the beasts, but the Prophets as our guides.

The principles of unity, concord and compassion taught by the Prophets are the very antithesis of those dominating the animal struggle for self-preservation, and we must choose between them, for they cannot be reconciled.

'Abdu'l-Baha says:-- In the world of nature the dominant note is the struggle for existence--the result of which is the survival of the fittest.
