“Verily, verily, I am God, no God is there but Me, the Lord of all created things. In truth all others except Me are My creatures. O, My creatures! Me alone do ye worship.”

... "Dwelling on the glorification of Him Whom God shall make manifest—exalted be His Manifestation—the Báb in the beginning of the Bayán saith: ‘He is the One Who shall proclaim under all conditions, “Verily, verily, I am God, no God is there but Me, the Lord of all created things. In truth all others except Me are My creatures. O, My creatures! Me alone do ye worship.”’ Likewise in another instance He, magnifying the Name of Him Who shall be made manifest, saith: ‘I would be the first to adore Him.’ Now it behoveth one to reflect upon the significance of the ‘Adorer’ and the ‘Adored One’, that perchance the people of the earth may partake of a dewdrop from the ocean of divine knowledge and may be enabled to perceive the greatness of this Revelation. Verily, He hath appeared and hath unloosed His tongue to proclaim the Truth. Well is it with him who doth acknowledge and recognize the truth, and woe betide the froward and the wayward.

O kindreds of the earth! Incline your ears unto the Voice from the divine Lote-Tree which overshadoweth the world and be not of the people of tyranny on earth—men who have repudiated the Manifestation of God and His invincible authority and have renounced His favours—they in truth are reckoned with the contemptible in the Book of God, the Lord of all mankind."
