Every true believer, if he is to deepen in his understanding
of the Cause of Bahá'u'lláh must needs combine profound faith in the unfailing
efficacy of His Message and His Covenant, with the humility of recognizing that
no one of this generation can claim to have embraced the vastness of His Cause
nor to have comprehended the manifold mysteries and potentialities it contains.
