The first duty prescribed by God for His servants is the
recognition of Him Who is the Dayspring of His Revelation and the Fountain of
His laws, Who representeth the Godhead in both the Kingdom of His Cause and the
world of creation. Whoso achieveth this duty hath attained unto all good; and
whoso is deprived thereof hath gone astray, though he be the author of every
righteous deed. It behoveth every one who reacheth this most sublime station,
this summit of transcendent glory, to observe every ordinance of Him Who is the
Desire of the world. These twin duties are inseparable. Neither is acceptable
without the other. Thus hath it been decreed by Him Who is the Source of Divine
inspiration.
- Baha'u'llah (The Kitab-i-Aqdas)
