In every city, all the divines and dignitaries rose to hinder and repress them, and girded up the loins of malice, of envy, and tyranny for their suppression. How great the number of those holy souls, those essences of justice, who, accused of tyranny, were put to death! And how many embodiments of purity, who showed forth naught but true knowledge and stainless deeds, suffered an agonizing death! Notwithstanding all this, each of these holy beings, up to his last moment, breathed the Name of God, and soared in the realm of submission and resignation. Such was the potency and transmuting influence which He exercised over them, that they ceased to cherish any desire but His will, and wedded their soul to His remembrance.

Bahá’u’lláh, The Ki tab-i-Ian, p. 234

Such hath been the patience, the calm, the resignation and contentment of this people that they have become the exponents of justice, and so great hath been their forbearance, that they have suffered themselves to be killed rather than kill, and this notwithstanding that these whom the world hath wronged have endured tribulations the like of which the history of the world hath never recorded, nor the eyes of any nation witnessed. What is it that could have induced them to reconcile themselves to these grievous trials, and to refuse to put forth a hand to repel them? What could have caused such resignation and serenity? The true cause is to be found in the ban which the Pen of Glory hath, day and night, chosen to impose, and in Our assumption of the reins of authority, through the power and might of Him Who is the Lord of all mankind.

Bahá’u’lláh, Epistle to the Son of the Wolf, p. 74-75

In physical strength and fortitude one of these Bahá’ís could have withstood many of their enemies, but they accepted martyrdom in the spirit of complete resignation and nonresistance. Many of them died, crying out, "O Lord! Forgive them; they know not what they do. If they knew, they would not commit this wrong." In the throes of martyrdom they willingly offered all they possessed in this life.

‘Abdu’l-Bahá, The Promulgation of Universal Peace, p. 384

O army of God! The Exalted One, the Báb, gave up His life. The Blessed Perfection gave up a hundred lives at every breath. He bore calamities. He suffered anguish. He was imprisoned. He was chained. He was made homeless and was banished to distant lands. Finally, then, He lived out His days in the Most Great Prison. Likewise, a great multitude of the lovers of God who followed this path have tasted the honey of martyrdom and they gave up everything - life, possessions, kindred - all they had. How many homes were reduced to rubble; how many dwellings were broken into and pillaged; how many a noble building went to the ground; how many a palace was battered into a tomb. And all this came about that humankind might be illumined, that ignorance might yield to knowledge, that men of earth might become men of heaven, that discord and dissension might be torn out by the roots, and the Kingdom of Peace become established over all the world. Strive ye now that this bounty become manifest, and this best-beloved of all hopes be realized in splendour throughout the community of man.

‘Abdu’l-Bahá, Selections from the Writings of ‘Abdu’l-Bahá, p. 73

Every day has certain needs.  In those early days the Cause needed Martyrs, and people who would stand all sorts of torture and persecution in expressing their faith and spreading the message sent by God.  Those days are, however, gone.  The Cause at present does not need martyrs who would die for their faith, but servants who desire to teach and establish the Cause throughout the world.   To live to teach in the present day is like being martyred in those early days.  It is the spirit that moves us that counts, not the act through which that spirit expresses itself, and that spirit is to serve the Cause of God with our heart and soul.

Shoghi Effendi, Living the Life, p.4

He urges you to make up your minds to do great, great deeds for the Faith; the condition of the world is steadily growing worse, and your generation must provide the saints, heroes, martyrs and administrators of future years. With dedication and will power you can rise to great heights.

Shoghi Effendi, Lights of Guidance, p. 629

At one of the darkest periods in the prolonged oppression of the dearly- loved, resolutely steadfast friends in Iran, Shoghi Effendi was moved to comfort them in a letter of astounding insight. "It is the shedding of the sacred blood of the martyrs in Persia" he wrote, "which, in this shining era, this resplendent, this gem-studded Bahá’í age, shall change the face of the earth into high heaven and, as revealed in the Tablets, raise up the tabernacle of the oneness of mankind in the very heart of the world, reveal to men's eyes the reality of the unity of the human race, establish the Most Great Peace, make of this lower realm a mirror for the Bahá Paradise, and establish beyond any doubt before all the peoples of the world the truth of the verse: '...the day when the Earth shall be changed into another Earth.'" Reflections like these, in adducing such wondrous future consequences from the horrific suffering to which our Iranian friends are subjected, illuminate the opportunity and the challenge facing us all at this crucial moment in the fortunes of the Cause.

The Universal House of Justice, Ridván 145, 1988, p. 1

In this day, the beloved of God must not hesitate or delay an instant in teaching the Cause of the manifestation; and reconciling words to the religion of majestic oneness; because, verily, in this day, to the soul who is the cause of guidance to another soul the recompense of a martyr in the way of God will be assuredly recorded by the pen of the Cause for his deed. This is from the bounty of God unto thee. Do according to what thou hast been commanded and do not be of those who tarry.

Compilations, Bahá’í Scriptures, p. 204

It is said there are three kinds of martyrdom: One is to stand bravely and meet death unflinchingly in the path of God without wavering or under torture denying for an instant their faith. The second is little by little to detach one’s heart entirely from the world, laying aside deliberately and voluntarily all vanities and worldly seductions, letting every act and word become a speaking monument and a fitting praise for the Holy Name of Bahá’u’lláh. The third is to do the most difficult things with such self-sacrifice that all behold it as your pleasure. To seek and to accept poverty with the same smile as you accept fortune. To make the sad, the sorrowful your associates instead of frequenting the society of the careless and gay. To yield to the decrees of God and to rejoice in the most violent calamities even when the suffering is beyond endurance. He who can fulfill these last conditions becomes a martyr indeed.
