"He hath appeared amongst you invested with a Revelation so great as to encompass all things ..."

"Take heed that ye dispute not idly concerning the Almighty and His Cause, for lo! He hath appeared amongst you invested with a Revelation so great as to encompass all things, whether of the past or of the future. Were We to address Our theme by speaking in the language of the inmates of the Kingdom, We would say: “In truth, God created that School ere He created heaven and earth, and We entered it before the letters B and E were joined and knit together.” Such is the language of Our servants in Our Kingdom; consider what the tongue of the dwellers of Our exalted Dominion would utter, for We have taught them Our knowledge and have revealed to them whatever had lain hidden in God’s wisdom. Imagine then what the Tongue of Might and Grandeur would utter in His All-Glorious Abode!

This is not a Cause which may be made a plaything for your idle fancies, nor is it a field for the foolish and faint of heart. By God, this is the arena of insight and detachment, of vision and upliftment, where none may spur on their chargers save the valiant horsemen of the Merciful, who have severed all attachment to the world of being. These, truly, are they that render God victorious on earth, and are the dawning-places of His sovereign might amidst mankind."

-Bahá'u'lláh, The Kitáb-i-Aqdas, p. 84
