The Cause of Baha'u'llah is the same as the Cause of Christ. It is the
same Temple and the same Foundation. Both of these are spiritual
springtimes and seasons of the soul-refreshing awakening and the cause of
the renovation of the life of mankind. The spring of this year is the same
as the spring of last year. The origins and ends are the same. The sun of
today is the sun of yesterday. In the coming of Christ, the divine
teachings were given in accordance with the infancy of the human race. The
teachings of Baha'u'llah have the same basic principles, but are according
to the stage of the maturity of the world and the requirements of this
illumined age.
