Bewildered, agonized and helpless, [humanity] watches this great and mighty wind of God invading the remotest and fairest regions of the earth, rocking its foundations, deranging its equilibrium, sundering its nations, disrupting the homes of its peoples, wasting its cities, driving into exile its kings, pulling down its bulwarks, uprooting its institutions, dimming its light, and harrowing up the souls of its inhabitants.

Shoghi Effendi, The Promised Day Is Come, p. 3

I am however assured and sustained by the conviction, never dimmed in my mind, that whatsoever comes to pass in the Cause of God, however disquieting in its immediate effects, is fraught with infinite Wisdom and tends ultimately to promote its interests in the world. Indeed, our experiences of the distant past, as well as of recent events, are too numerous and varied to permit of any misgiving or doubt as to the truth of this basic principle — a principle which throughout the vicissitudes of our sacred mission in this world we must never disregard or forget.

Shoghi Effendi, Bahá’í Administration, p. 27

Ours rather the duty, however confused the scene, however dismal the present outlook, however circumscribed the resources we dispose of, to labor serenely, confidently, and unremittingly to lend our share of assistance, in whichever way circumstances may enable us, to the operation of the forces which, as marshaled and directed by Bahá’u’lláh, are leading humanity out of the valley of misery and shame to the loftiest summits of power and glory.

Shoghi Effendi, The Promised Day Is Come, p.124

Having said all the foregoing, we pause to assure you of our full awareness of the great burdens you carry and of the ceaseless calls upon you to render services in the absence of adequate resources. Do not despair. Your capacity to respond will match any challenge that may confront you in these troubled times; you have only to act on principle.

The divine promises to your community are certain; the blessings of Bahá’u’lláh are assured as you strive to fulfill His purpose. The wings of the beloved Master remain spread over you that you may succeed in discharging the tasks He has especially entrusted to your care. And our love ever surrounds you and your cherished community, growing stronger at every moment. Step forward then to meet the requirements of the hour with undiminished hope and confidence.

Your concern about the future in these troubled times is understandable. There is every reason to expect that the world will experience travail and testing as never before, but we do not know what form these upheavals will take, when exactly they will come, how severe they will be, nor how long they will last. In a letter dated 30 September 1950 written on behalf of the beloved Guardian to an individual believer, it is stated: He does not feel that fear — for ourselves or for others — solves any problems, or enables us to better meet it if it ever does arise. We do not know what the future holds exactly, or how soon we may all pass through another ordeal worse than the last one. The important aspect for the Bahá’ís is that their attitude and actions in response to the pending catastrophe be correct. We all know that the Cause of Bahá’u’lláh is the world's only salvation, and that our duty is to actively teach receptive souls, and to do our utmost to help in the consolidation of the institutions of the Faith. Only in this way can we contribute our share of servitude at His Threshold, and we should then leave the rest to Him.
