Mormons still await "The Day" that the Holy Ghost, Whom they believe is still a Spirit-Man without a physical body, will "come down to get a body" and perform some great and holy Mission on Earth.

Bahá'ís know...that "Day" has already come!

In August of 1843, Joseph Smith declared that the Holy Ghost "was now in a state of probation" (i.e. "state of probation" is a Book of Mormon term meaning an earthly mortal life) Joseph Smith never claimed to be the Holy Ghost incarnate! But, there was a Man living in Persian (Iran) in 1843, Who later claimed to be the Holy Ghost incarnate, or Spirit of Truth.

The Bahá'í Faith was founded by BAHÁ'U'LLÁH (baw-haw-Oh-LAW) in 1863, in Baghdad, Iraq. He was born in 1817 in the province of Noor ("Light"), Iran. He was a direct descendant of Bostanai of Iraq (a direct descendant of King David of Israel) and Princess Dar'rah of Persia; a descendant of King Cyrus of Persia. His birth-name was Mirza Husein-Ali Noori (Arabic: "Prince Beauty-Exalted of Light"). He has "Noor" ("light") as a "covering" (sur-name).

The name-title Bahá'u'lláh (baw-haw-Oh-LAW) means "The Glory of God" in Arabic. The Doctrine & Covenants (a purported book of Revelations to Joseph the Seer) declares that those who inherit the Celestial Kingdom will receive "the Glory of God" (D&C ????) as their divine inheritance.

We believe that Bahá'u'lláh was the Spirit of Truth promised by Jesus in John chapter 16!

Jesus said:

Howbeit when he, the Spirit of Truth is come, he will guide you unto all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak; and he will shew you things to come. He shall glorify me.... (John 16:13-14)

Verily, He Who is the Spirit of Truth is now come to guide you unto all truth. He speaketh not as prompted by HIs own self, but as bidden by Him Who is the All-Wise. Say, this is the One Who hath glorified the Son and hath exalted His Cause. (Tablets of Bahá'u'lláh, p.12)
