I have my reservations that Baha'u'llah was All-Powerful or All-Knowing or All-Wise.
Did Baha'u'llah ever make any such claims? If not I think it is just your personal opinion.
I can believe that he was Sovereign, because God gave Him sovereignty upon this earth, at least during His dispensation, until another Manifestation of God appears.
And further We have said: "That which God hath ordained as the sovereign remedy and mightiest instrument for the healing of the world is the union of all its peoples in one universal Cause, one common Faith. This can in no wise be achieved except through the power of a skilled, an
all-powerful, and inspired Physician. By My life! This is the truth, and all else naught but error. Each time that Most Mighty Instrument hath come, and that Light shone forth from the Ancient Dayspring, He was withheld by ignorant physicians who, even as clouds, interposed themselves between Him and the world. It failed therefore, to recover, and its sickness hath persisted until this day. They indeed were powerless to protect it, or to effect a cure, whilst He Who hath been the Manifestation of Power amongst men was withheld from achieving His purpose, by reason of what the hands of the ignorant physicians have wrought.
(Baha'u'llah, Epistle to the Son of the Wolf, p. 62)
"O King! I was but a man like others, asleep upon My couch, when lo, the breezes of the All-Glorious were wafted over Me, and taught Me the
knowledge of all that hath been. This thing is not from Me, but from One Who is Almighty and All-Knowing. And He bade Me lift up My voice between earth and heaven, and for this there befell Me what hath caused the tears of every man of understanding to flow. The learning current amongst men I studied not; their schools I entered not. Ask of the city wherein I dwelt, that thou mayest be well assured that I am not of them who speak falsely. This is but a leaf which the winds of the will of thy Lord, the Almighty, the All-Praised, have stirred. Can it be still when the tempestuous winds are blowing? Nay, by Him Who is the Lord of all Names and Attributes! They move it as they list. The evanescent is as nothing before Him Who is the Ever-Abiding. His all-compelling summons hath reached Me, and caused Me to speak His praise amidst all people. I was indeed as one dead when His behest was uttered. The hand of the will of thy Lord, the Compassionate, the Merciful, transformed Me."
(Baha'u'llah, Epistle to the Son of the Wolf, p. 11)
And again in another connection: "Revile ye not one another. We, verily, have come to unite and weld together all that dwell on earth. Unto this beareth witness what the ocean of Mine utterance hath revealed amongst men, and yet most of the people have gone astray. If anyone revile you, or trouble touch you, in the path of God, be patient, and put your trust in Him Who heareth, Who seeth. He, in truth, witnesseth, and perceiveth, and doeth what He pleaseth, through the power of His sovereignty. He, verily, is the Lord of strength, and of might. In the Book of God, the Mighty, the Great, ye have been forbidden to engage in contention and conflict. Lay fast hold on whatever will profit you, and profit the peoples of the world. Thus commandeth you the King of Eternity, Who is manifest in His Most Great Name. He, verily, is the Ordainer, the
All-Wise."
(Baha'u'llah, Epistle to the Son of the Wolf, p. 24)
O Queen in London! Incline thine ear unto the voice of thy Lord, the Lord of all mankind, calling from the Divine Lote-Tree: Verily, no God is there but Me, the Almighty, the
All-Wise!
(Baha'u'llah, Epistle to the Son of the Wolf, p. 59)
