The Promised One is come

Say: O peoples of the earth! Destroy the abodes of negligence with the hands of power and assurance, and raise up the mansions of true knowledge within your hearts, that the All-Merciful may shed the radiance of His light upon them. Better is this for you  than all whereon the sun shineth, and unto this beareth witness He Who holdeth within His grasp the ultimate decree. The Breeze of God hath been wafted over the world at the advent of the Desired One in His great glory, whereupon every stone and clod of earth hath cried out: "The Promised One is come! The Kingdom is God’s, the Mighty, the Gracious, the Forgiving."
Beware lest human learning debar thee from Him Who is the Supreme Object of all knowledge, or lest the world deter thee from the One Who created it and set it upon its course. Arise in the name of thy Lord, the God of Mercy, amidst the peoples of the earth, and seize thou the Cup of Life with the hands of confidence. First drink thou therefrom, and proffer it then to such as turn towards it amongst the peoples of all faiths. Thus hath the Moon of Utterance risen above the horizon of wisdom and understanding.

Baha'u'llah, The Summons of the Lord of Hosts, p. 55
