O people of the Bayán, I adjure you by your Lord, the God of mercy, to look with the eye of fairness upon this utterance which hath been sent down through the power of truth, and not to be of those who see the testimony of God yet reject and deny it. They, in truth, are of those who will assuredly perish. The Point of the Bayán hath explicitly made mention in this verse of the exaltation of My Cause before His own Cause; unto this will testify every just and understanding mind. As ye can readily witness in this day, its exaltation is such as none can deny save those whose eyes are drunken in this mortal life and whom a humiliating chastisement awaiteth in the life to come.

Teach your children the verses revealed from the heaven of majesty and power, so that, in most melodious tones, they may recite the Tablets of the All-Merciful in the alcoves within the Mashriqu'l-Adhkárs. Whoever hath been transported by the rapture born of adoration for My Name, the Most Compassionate, will recite the verses of God in such wise as to captivate the hearts of those yet wrapped in slumber. Well is it with him who hath quaffed the Mystic Wine of everlasting life from the utterance of his merciful Lord in My Name -- a Name through which every lofty and majestic mountain hath been reduced to dust.

the teachers
In a Tablet, 'Abdu'l-Bahá compares teachers who are involved with the spiritual education of the child to the "spiritual father" who "endoweth his child with everlasting life". He explains that this is the reason that "teachers are listed among the heirs" in the "law of God".
Bahá'u'lláh specifies the conditions under which the teacher inherits and the share he or she receives (Q&A 33).
