That which is preeminent above all other gifts, is incorruptible in nature, and pertaineth to God Himself, is the gift of Divine Revelation. Every bounty conferred by the Creator upon man, be it material or spiritual, is subservient unto this. It is, in its essence, and will ever so remain, the Bread which cometh down from Heaven. It is God’s supreme testimony, the clearest evidence of His truth, the sign of His consummate bounty, the token of His all-encompassing mercy, the proof of His most loving providence, the symbol of His most perfect grace. He hath, indeed, partaken of this highest gift of God who hath recognized His Manifestation in this Day. Render thanks unto thy Lord for having vouchsafed unto thee so great a bounty. Lift up thy voice and say: All praise be to Thee, O Thou, the Desire of every understanding heart!
(Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 194)
