He, in truth, hath offered up His life as a ransom for the redemption of the world.

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 315

For the space of three years, that Luminary of perfections [Jesus] walked about the fields of Palestine and in the neighborhood of Jerusalem, leading all men into the dawn of redemption, teaching them how to acquire spiritual qualities and attributes well-pleasing to God. Had the people of Israel believed in that beauteous Countenance, they would have girded themselves to serve and obey Him heart and soul, and through the quickening fragrance of His Spirit they would have regained their lost vitality and gone on to new victories. Alas, of what avail was it; they turned away and opposed Him. They rose up and tormented that Source of Divine knowledge, that Point where the Revelation had come down -- all except for a handful who, turning their faces toward God, were cleansed of the stain of this world and found their way to the heights of the placeless Realm. They inflicted every agony on that Wellspring of grace until it became impossible for Him to live in the towns, and still He lifted up the flag of salvation and solidly established the fundamentals of human righteousness, that essential basis of true civilization.

‘Abdu’l-Bahá, The Secret of Divine Civilization, p. 80-81

It is certain that the greatest of instrumentalities for achieving the advancement and the glory of man, the supreme agency for the enlightenment and the redemption of the world, is love and fellowship and unity among all the members of the human race. Nothing can be effected in the world, not even conceivably, without unity and agreement, and the perfect means for engendering fellowship and union is true religion .

‘Abdu’l-Bahá, The Secret of Divine Civilization, p. 73

Jesus, then, founded the sacred Law on a basis of moral character and complete spirituality, and for those who believed in Him He delineated a special way of life which constitutes the highest type of action on earth. And while those emblems of redemption were to outward seeming abandoned to the malevolence and persecution of their tormentors, in reality they had been delivered out of the hopeless darkness which encompassed the Jews and they shone forth in everlasting glory at the dawn of that new day.

‘Abdu’l-Bahá, The Secret of Divine Civilization, p. 82

Those qualities which the philosophers attained when they had reached the very heights of their wisdom, those noble human attributes which characterized them at the peak of their perfection, would be exemplified by the believers as soon as they accepted the Faith. Observe how those souls who drank the living waters of redemption at the gracious hands of Jesus, the Spirit of God, and came into the sheltering shade of the Gospel, attained to such a high plane of moral conduct that Galen, the celebrated physician, although not himself a Christian, in his summary of Plato's Republic extolled their actions.

‘Abdu’l-Bahá, The Secret of Divine Civilization, p. 83-84

Verily I ask of the Lord that He make you standards of salvation and banners of redemption, rippling high over the valleys and hills.

‘Abdu’l-Bahá, Selections from the Writings of ‘Abdu’l-Bahá, p. 95

Verily the prison is my paradise and the chains my necklace; my balance (or testing) is my redemption (or salvation) and the castle is my fortified safety, for this imprisonment is in the path of my Lord and it is my salvation, my joy, my gratitude and happiness.

‘Abdu’l-Bahá, Tablets of ‘Abdu’l-Bahá v2, p. 333

-- such is the spectacle presented to men's eyes, as a result of the sweeping changes which this revolutionizing Force, as yet in the initial stage of its operation, is now producing in the life of the entire planet.

So sad and moving a spectacle [economic anarchy and strife], bewildering as it must be to every observer unaware of the purposes, the prophecies, and promises of Bahá’u’lláh, far from casting dismay into the hearts of His followers, or paralyzing their efforts, cannot but deepen their faith, and excite their enthusiastic eagerness to arise and display, in the vast field traced for them by the pen of ‘Abdu’l-Bahá, their capacity to play their part in the work of universal redemption proclaimed by Bahá’u’lláh.

Shoghi Effendi, The Advent of Divine Justice, p. 47-48

I appeal to the New World champions of the New World Order of Bahá’u’lláh to stand fast at this tragic hour in the fortunes of mankind and the challenging state of the evolution of the Faith. I beg them to close their ranks jointly, severally and vow themselves to incomparably sublime task whose operation must hasten the ascendancy of the beloved Cause and the spiritual redemption of a reconstructed mankind.

Shoghi Effendi, Messages to America, p. 43-44

The generality of mankind, blind and enslaved, is wholly unaware of the healing power with which this community has been endowed, nor can it as yet suspect the role which this same community is destined to play in its redemption.

Shoghi Effendi, Lights of Guidance, p. 135

The gross materialism that engulfs the entire nation at the present hour; the attachment to worldly things that enshrouds the souls of men; the fears and anxieties that distract their minds; the pleasure and dissipations that fill their time, the prejudices and animosities that darken their outlook, the apathy and lethargy that paralyze their spiritual faculties--these are among the formidable obstacles that stand in the path of every would-be warrior in the service of Bahá’u’lláh, obstacles which he must battle against and surmount in his crusade for the redemption of his own countrymen.

Shoghi Effendi, Citadel of Faith, p. 148

The Revelation associated with the Faith of Jesus Christ focused attention primarily on the redemption of the individual and the molding of his conduct, and stressed, as its central theme, the necessity of inculcating a high standard of morality and discipline into man, as the fundamental unit in human society. Nowhere in the Gospels do we find any reference to the unity of nations or the unification of mankind as a whole. When Jesus spoke to those around Him, He addressed them primarily as individuals rather than as component parts of one universal, indivisible entity. The whole surface of the earth was as yet unexplored, and the organization of all its peoples and nations as one unit could, consequently, not be envisaged, how much less proclaimed or established. What other interpretation can be given to these words, addressed specifically by Bahá’u’lláh to the followers of the Gospel, in which the fundamental distinction between the Mission of Jesus Christ, concerning primarily the individual, and His own Message, directed more particularly to mankind as a whole, has been definitely established:  "Verily, He [Jesus] said: 'Come ye after Me, and I will make you to become fishers of men.' In this day, however, We say: 'Come ye after Me, that We may make you to become the quickeners of mankind.

Shoghi Effendi, The Promised Day is Come, p. 119-120

They should persevere in their task, undaunted by the rising tide of calamity and despair which afflicts the world, and which is mysteriously paving the way for its unification and ultimate redemption.

Shoghi Effendi, Dawn of a New Day, p. 87-88

If we are to be worthy of the sacrifices of these valiant friends, and if we are not to betray the trust that Bahá’u’lláh has placed upon us for the redemption of mankind in this hour of its acute need, we must not fail to seize the opportunities now before us.

The Universal House of Justice, Messages 1963 to 1986, p. 613-614

The all-important teaching work must be imaginatively, persistently and sacrificially continued, ensuring the enrollment of ever larger numbers who will provide the energy, the resources and spiritual force to enable the beloved Cause to worthily play its part in the redemption of mankind.

Universal House of Justice, Ridván Message, 1987

The working out of God's Major Plan proceeds mysteriously in ways directed by Him alone, but the Minor Plan that He has given us to execute, as our part in His grand design for the redemption of mankind, is clearly delineated. It is to this work that we must devote all our energies, for there is no one else to do it.

Universal House of Justice, Wellspring of Guidance, p. 133-34

We are told by Shoghi Effendi that two great processes are at work in the world: the great Plan of God, tumultuous in its progress, working through mankind as a whole, tearing down barriers to world unity and forging humankind into a unified body in the fires of suffering and experience. This process will produce, in God s due time, the Lesser Peace, the political unification of the world. Mankind at that time can be likened to a body that is unified but without life. The second process, the task of breathing life into this unified body -- of creating true unity and spirituality culminating in the Most Great Peace -- is that of the Bahá’ís, who are labouring consciously, with detailed instructions and continuing divine guidance, to erect the fabric of the Kingdom of God on earth, into which they call their fellow-men, thus conferring upon them eternal life.

Universal House of Justice, Wellspring of Guidance, p. 133-34

Your aim is the redemption of mankind from its godlessness, its ignorance, its confusion and conflict. You will succeed, as those before you succeeded, by sacrifice to the Cause of God. The deeds and services required of you now, will shine in the future, even as those of your spiritual predecessors shine today and will forever shine in the annals of the Cause.

The Universal House of Justice, Messages 1963 to 1986, p. 172

The Jews taught that every man who commits sin must redeem himself by the sacrifice of an animal. When Christ taught that He was the living bread that gave life to the world, His followers understood "life" to mean, the forgiveness of sins. But the real redemption is, when a man wishing to give the knowledge of their God to the people, sacrifices himself -- that is to say, he strips himself from all the cares of the body, from his rest, comforts, and pleasures, and thinks only of the service of God and giving the truth to the people.
