At the time of the Revelation all men are equal in rank. By reason, however, of their acceptance or rejection, rise or fall, motion or stillness, recognition or denial, they come to differ thereafter. For instance, the one true God, magnified be His glory, speaking through the intermediary of His Manifestation, doth ask: “Am I not your Lord?” Every soul that answereth “Yea, verily!” is accounted among the most distinguished of all men in the sight of God. Our meaning is that ere the Word of God is delivered, all men are deemed equal in rank and their station is one and the same. It is only thereafter that differences appear, as thou hast no doubt observed.
Bahá’u’lláh, Tabernacle of Unity, Section II, Verset: 2.50
In confirmation of the exalted rank of the true believer, referred to by Bahá’u’lláh, He reveals the following: “The station which he who hath truly recognized this Revelation will attain is the same as the one ordained for such prophets of the house of Israel as are not regarded as Manifestations ‘endowed with constancy.’”
Estimating the station of the true believer He remarks: “By the sorrows which afflict the beauty of the All-Glorious! Such is the station ordained for the true believer that if to an extent smaller than a needle’s eye the glory of that station were to be unveiled to mankind, every beholder would be consumed away in his longing to attain it.
For this reason it hath been decreed that in this earthly life the full measure of the glory of his own station should remain concealed from the eyes of such a believer.” “If the veil be lifted,” He similarly affirms, “and the full glory of the station of those who have turned wholly towards God, and in their love for Him renounced the world, be made manifest, the entire creation would be dumbfounded.”
