How many blessed souls have longed for this radiant century, their utmost hopes and desires centered upon the happiness and joy of one such day as this. Many the nights they passed sleepless and lamenting until the very morn in longing anticipation of this age, yearning to realize even an hour of this time. God has favored you in this century and has specialized you for the realization of its blessings. Therefore, you must praise and thank God with heart and soul in appreciation of this great opportunity and the attainment of this infinite bestowal -- that such doors have been opened before your faces, that such abundance is pouring down from the cloud of mercy and that these refreshing breezes from the paradise of Abha are resuscitating you. You must become of one heart, one spirit and one susceptibility. May you become as the waves of one sea, stars of the same heaven, fruits adorning the same tree, roses of one garden in order that through you the oneness of humanity may establish its temple in the world of mankind, for you are the ones who are called to uplift the cause of unity among the nations of the earth.
First, you must become united and agreed among yourselves. You must be exceedingly kind and loving toward each other, willing to forfeit life in the pathway of another's happiness. You must be ready to sacrifice your possessions in another's behalf. The rich among you must show compassion toward the poor, and the well-to-do must look after those in distress. In Persia the friends offer their lives for each other, striving to assist and advance the interests and welfare of all the rest. They live in a perfect state of unity and agreement. Like the Persian friends you must be perfectly agreed and united to the extent and limit of sacrificing life. Your utmost desire must be to confer happiness upon each other. Each one must be the servant of the others, thoughtful of their comfort and welfare. In the path of God one must forget himself entirely. He must not consider his own pleasure but seek the pleasure of others. He must not desire glory nor gifts of bounty for himself but seek these gifts and blessings for his brothers and sisters. It is my hope that you may become like this, that you may attain to the supreme bestowal and be imbued with such spiritual qualities as to forget yourselves entirely and with heart and soul offer yourselves as sacrifices for the Blessed Perfection. You should have neither will nor desire of your own but seek everything for the beloved of God and live together in complete love and fellowship. May the favors of Bahá'u'lláh surround you from all directions. This is the greatest bestowal and supreme bounty. These are the infinite favors of God.
