By this will 'Abdu'l-Baha was constituted His father's representative and the expounder of His teachings, and the family and relatives of Baha'u'llah and all believers were instructed to turn to Him and obey Him.

By this arrangement sectarianism and division were provided against and the unity of the Cause assured.
Prophethood of Baha'u'llah It is important to have clear ideas of Baha'u'llah's Prophethood.

His utterances, like those of other divine "Manifestations," may be divided into two classes, in one of which He writes or speaks simply as a man who has been charged by God with a message to His fellows, while in the other class the words purport to be the direct utterance of God Himself.
He writes in the Book of Iqan:-- We have already in the foregoing pages assigned two stations unto each of the Luminaries arising from the Daysprings of eternal holiness.

One of these stations, the station of essential unity, We have already explained.

"No distinction do We make between any of them." [Qur'an 2:136] The other is the station of distinction, and pertaineth to the world of creation and to be the limitations thereof.
