Two opposing types of conduct that Bahá’u’lláh doesn’t approve

In this Day, We can neither approve the conduct of the fearful that seeketh to dissemble his faith, nor sanction the behaviour of the avowed believer that clamorously asserteth his allegiance to this Cause. Both should observe the dictates of wisdom, and strive diligently to serve the best interests of the Faith.

Bahá’u’lláh’s amazement as a boy on pointless discourses by some clerics

Bahá'u'lláh ... records that on one occasion, when visiting his future mother-in-law, he listened to a cleric with a large turban expounding on whether the arch-angel Gabriel was the greater or Qanbar, the servant of the Imam ‘Ali. He writes that although he was still but a boy, he was astonished at the ignorance of these elders and when an opportunity came, he expressed his thoughts saying that since Gabriel is stated in Qur’an to be the one through whom the Word of God is revealed to the prophet Muhammad, then even Qanbar's master the Imam ‘Ali would not reach that station. Bahá'u'lláh states that some time later, he visited Qum and was dismayed to find the same cleric expounding the same sort of pointless and fruitless discourse.

The sufferings of Baha’u’llah: “By Thy might! No pen can recount them, nor can any tongue describe or number them.”

Glorified be Thy name, O Lord my God! Thou beholdest my dwelling-place, and the prison into which I am cast, and the woes I suffer. By Thy might! No pen can recount them, nor can any tongue describe or number them. I know not, O my God, for what purpose Thou hast abandoned me to Thine adversaries. Thy glory beareth me witness! I sorrow not for the vexations I endure for love of Thee, nor feel perturbed by the calamities that overtake me in Thy path. My grief is rather because Thou delayest to fulfill what Thou hast determined in the Tablets of Thy Revelation, and ordained in the books of Thy decree and judgment.

My blood, at all times, addresseth me saying: “O Thou Who art the Image of the Most Merciful! How long will it be ere Thou riddest me of the captivity of this world, and deliverest me from the bondage of this life? Didst Thou not promise me that Thou shalt dye the earth with me, and sprinkle me on the faces of the inmates of Thy Paradise?” To this I make reply: “Be thou patient and quiet thyself. The things thou desirest can last but an hour. As to me, however, I quaff continually in the path of God the cup of His decree, and wish not that the ruling of His will should cease to operate, or that the woes I suffer for the sake of my Lord, the Most Exalted, the All-Glorious, should be ended. Seek thou my wish and forsake thine own. Thy bondage is not for my protection, but to enable me to sustain successive tribulations, and to prepare me for the trials that must needs repeatedly assail me. Perish that lover who discerneth between the pleasant and the poisonous in his love for his beloved! Be thou satisfied with what God hath destined for thee. He, verily, ruleth over thee as He willeth and pleaseth. No God is there but Him, the Inaccessible, the Most High.”

- Baha’u’llah  (‘Prayers and Meditations by Baha’u’llah’)

 

By acquiring “greater love for Bahá'u'lláh” the believers will have “greater love for each other”

The thing the friends need -- everywhere -- is a greater love for each other, and this can be acquired by greater love for Bahá'u'lláh; for if we love Him deeply enough, we will never allow personal feelings and opinions to hold His Cause back; we will be willing to sacrifice ourselves to each other for the sake of the Faith, and be, as the Master said, one soul in many bodies.

“Persian poems revealed by the Blessed Beauty”

I earnestly hope that thou wilt memorize all the Persian poems revealed by the Blessed Beauty and wilt sing them in a voice of incomparable sweetness at Bahá'í meetings and gatherings. The day is not far distant when these poems will be set to Western music and the sweet accents of these songs will reach the Abha Kingdom with exceeding joy and gladness. 

- ‘Abdu’l-Baha (From a Tablet; The Compilation of Compilations, vol. III, The Importance of Arts in Promoting the Faith)

“the most weighty and sacred of all the works of Bahá'u'lláh”

Whether in the Kitáb-i-Aqdas, the most weighty and sacred of all the works of Bahá'u'lláh, or in the Kitáb-i-'Ahd, the Book of His Covenant, or in the Suriy-i-Ghusn (Tablet of the Branch), such references as have been recorded by the pen of Bahá'u'lláh -- references which the Tablets of His Father addressed to Him mightily reinforce -- invest 'Abdu'l-Bahá with a power, and surround Him with a halo, which the present generation can never adequately appreciate.
