"That which alone is exempt from change is His own Self, the All-Merciful, the Most Compassionate..."

"Would ye gainsay, O people, the very thing that your eyes behold? Woe unto you, O assemblage of deniers!
That which alone is exempt from change is His own Self, the All-Merciful, the Most Compassionate, were ye to gaze with the eye of insight, while all else beside Him can be altered by an act of His Will. He, verily, is the All-Powerful, the Almighty, the All-Wise."

-Bahá'u'lláh, The Summons of the Lord of Hosts, p. 37
