The friends and handmaids of the Merciful must render service to the oneness of the human world and show love and fellowship towards all people. They must deal with all kindreds, religions, and creeds with the utmost sincerity, goodwill, love, and kindness. They must consider how the tree of their existence may bring forth good fruit, and no fruit is greater than love and fellowship with all humanity. Bahá’u’lláh, addressing the world of humanity, saith: “Ye are all the leaves of one tree and the fruits of one branch.” Such being the case, the existence of bonds of kinship, brotherhood, sonhood, and fatherhood amongst all human beings is proven and established. Strive ye, then, with heart and soul to conduct yourselves in accordance with these teachings of Bahá’u’lláh. Be a shelter and refuge to every oppressed one, and a helper and supporter to every vanquished one. Be a skilled physician to every sick one, and a healing balm to every wounded one. Offer a safe haven to every fearful one, and bring comfort and solace to every dismayed one. Gladden the heart of every sorrowful one, and bring joy to every tearful one. Be as refreshing water to every thirsty one, and as heavenly food to every hungry one. Become the cause of glory to every abased one, and the source of blessings to every poor one.
