In the next two Hidden Words Bahá’u’lláh tells of His fears for us, and He reminds us that He will not be with us in this world forever.
“O MY CHILDREN! I fear lest, bereft of the melody of the dove of heaven, ye will sink back to the shades of utter loss, and, never having gazed upon the beauty of the rose, return to water and clay.”[Bahá’u’lláh, The Hidden Words, No. P13.]
“O SON OF SPIRIT! The time cometh, when the nightingale of holiness will no longer unfold the inner mysteries and ye will all be bereft of the celestial melody and of the voice from on high.” [Bahá’u’lláh, The Hidden Words, No. P15.]
