"He feels that if ... ponders more deeply about the fundamentals of Divine
Revelation, she will also come to understand the Guardianship. Once the
mind and heart have grasped the fact that God guides men through a
Mouthpiece, a human being, a Prophet, infallible and unerring, it is only
a logical projection of this acceptance to also accept the station of
'Abdu'l-Baha and the Guardians. The Guardians are the evidence of the
maturity of mankind in the sense that at long last men have progressed to
the point of having one world, and of needing one world management for
human affairs. In the spiritual realm they have also reached the point
where God could leave, in human hands (i.e. the Guardians) guided directly
by the Bab and Baha'u'llah, as the Master states in His Will, the affairs
of His Faith for this Dispensation. This is what is meant by 'this is the
day which will not be followed by night.' In this Dispensation, divine
guidance flows on to us in this world after the Prophet's ascension,
through first the Master, and then the Guardians. If a person can accept
Baha'u'llah's function, it should not present any difficulty to them to
also accept what He has ordained in a Divinely guided individual in
matters pertaining to the Faith."
