And if they ask regarding your belief in Bahá’u’lláh, you should reply that we consider Him as the foremost Teacher and Educator of the world in this age, and make clear, explaining in detail, that these teachings regarding universal peace and other subjects were revealed by the pen of Bahá’u’lláh fifty years ago and have already been published in Persia and India and spread abroad throughout the whole world. In the beginning all were incredulous about the idea of universal peace, considering it an impossibility. Further, speak of the greatness of Bahá’u’lláh, of the events that took place in Persia and Turkey, of the astonishing influence that He exerted, of the contents of the Epistles which He addressed to all the sovereigns, and of their fulfilment. Also speak of the spread of the Bahá’í Cause. Associate with the Committee of Universal Peace at The Hague as much as possible, showing them every courtesy.

My hope is that the divine confirmations may continually assist thee....
