Baha'u'llah writes:
 
            " Consider the sun. were it to say now,' I am the sun of yesterday, ' it would  speak
              the truth. And should it, bearing the sequence of time  in mind, claim  to  be  other 
              than that sun, it still would speak the truth. In like manner, if it be  said  that all the
              days are but one and  the  same, it  is  correct  and  true. And  if  it  be  said , with
              respect to their particular names and designations, that  they  differ, that  again is  
              true. For though they are the same, yet one doth  recognize  in  each  a  separate
              designation , a  specific  attribute, a  particular  character . Conceive  accordingly
              the distinction, variation , and  unity  characteristic  of  various  Manifestations  of
              holiness, that  thou mayest comprehend all allusions  made  by  the Creator of all
              names, and attributes  to the mysteries of distinction and unity, and  discover  the
              answer to  thy question  as  to  why  that everlasting  beauty  should  have, at the
              sundry times, called Himself by different names and titles.  "
