As regards your question: Bahá’u’lláh is, of course, not God and not the Creator; but through Him we can know God, and because of this position of Divine Intermediary, in a sense, He is all (or the other Prophets) we can ever know of that Infinite Essence which is God. Therefore, we address ourselves in prayer and thought to Him, or through Him to that Infinite Essence behind and beyond Him.
