The blessed Person of the Promised One is interpreted in the
Holy Book as the Lord of Hosts, i.e., the heavenly armies. By heavenly armies
those souls are intended who are entirely freed from the human world,
transformed into celestial spirits and have become divine angels. Such souls
are the rays of the Sun of Reality who will illumine all the continents. Each
one is holding in his hand a trumpet, blowing the breath of life over all the
regions. They are delivered from human qualities and the defects of the world
of nature, are characterized with the characteristics of God, and are attracted
with the fragrances of the Merciful. Like unto the apostles of Christ, who were
filled with Him, these souls also have become filled with His Holiness
Bahá'u'lláh, i.e., the love of Bahá'u'lláh has so mastered every organ, part
and limb of their bodies, as to leave no effect by the promptings of the human
world…. Any soul from among the believers of Bahá'u'lláh who attains to this
station, will become known as the Apostle of Bahá'u'lláh.
(‘Abdu'l-Baha, ‘Tablets
of the Divine Plan)
