April 18

From the beginning of His childhood Bahá’u’lláh was possessed of such astonishing qualities, signs, and utterances as to amaze every soul. All the dignitaries of Persia would say: “This youth is wrought of a rare substance”, and everyone, even the enemies and the envious, bore witness to His knowledge, grace, wisdom, understanding, intelligence, and perception. Among other things, it was acknowledged by all that He had neither entered a school nor received a religious education. Nonetheless, His knowledge and perfections were well recognized. The learned men of Persia would submit to Him the difficult questions that perplexed their minds, and He would resolve them. To this day, and in spite of their hostility, the dignitaries of Persia bear witness to this matter.

In sum, no one, whether in Persia or even throughout the East, denies Bahá’u’lláh’s knowledge, perfection, greatness, and ability. At most they claim that this Man subverted the foundations of the Law of God, that by means of His shrewdness, intelligence, knowledge, wisdom, eloquence, and sagacity He led astray a vast multitude, and that He thus undermined the perspicuous religion of God. But they do not deny His greatness.
