This series of fourteen letters addressed to the Bahá’ís of the United States and Canada during World War I became the charter for the growth of the Bahá’í community throughout the world.

‘Abdu’l-Bahá’s Tablets of the Divine Plan can be read in full at the Bahá’í Reference Library. Some extracts are shared below.

Consider the work of former generations. During the lifetime of Jesus Christ the believing, firm souls were few and numbered, but the heavenly blessings descended so plentifully that in a number of years countless souls entered beneath the shadow of the Gospel. God has said in the Qur’án: “One grain will bring forth seven sheaves, and every sheaf shall contain one hundred grains.” In other words, one grain will become seven hundred; and if God so wills He will double these also. It has often happened that one blessed soul has become the cause of the guidance of a nation. Now we must not consider our ability and capacity, nay, rather, we must fix our gaze upon the favors and bounties of God, in these days, Who has made of the drop a sea, and of the atom a sun.

O THOU Incomparable God! O Thou Lord of the Kingdom! These souls are Thy heavenly army. Assist them and, with the cohorts of the Supreme Concourse, make them victorious, so that each one of them may become like unto a regiment and conquer these countries through the love of God and the illumination of divine teachings.

O God! Be Thou their supporter and their helper, and in the wilderness, the mountain, the valley, the forests, the prairies and the seas, be Thou their confidant—so that they may cry out through the power of the Kingdom and the breath of the Holy Spirit.

Verily, Thou art the Powerful, the Mighty and the Omnipotent, and Thou art the Wise, the Hearing and the Seeing.

O ye friends of God! Exert ye with heart and soul, so that association, love, unity and agreement be obtained between the hearts, all the aims may be merged into one aim, all the songs become one song and the power of the Holy Spirit may become so overwhelmingly victorious as to overcome all the forces of the world of nature. Exert yourselves; your mission is unspeakably glorious…

This phenomenal world will not remain in an unchanging condition even for a short while. Second after second it undergoes change and transformation. Every foundation will finally become collapsed; every glory and splendor will at last vanish and disappear, but the Kingdom of God is eternal and the heavenly sovereignty and majesty will stand firm, everlasting. Hence in the estimation of a wise man the mat in the Kingdom of God is preferable to the throne of the government of the world…

Consequently, those souls who are in a condition of the utmost severance, purified from the defects of the world of nature, sanctified from attachment to this earth, vivified with the breaths of eternal life—with luminous hearts, with heavenly spirit, with attraction of consciousness, with celestial magnanimity, with eloquent tongues and with clear explanations—such souls must hasten and travel through all parts of the Central States. In every city and village they must occupy themselves with the diffusion of the divine exhortations and advices, guide the souls and promote the oneness of the world of humanity. They must play the melody of international conciliation with such power that every deaf one may attain hearing, every extinct person may be set aglow, every dead one may obtain new life and every indifferent soul may find ecstasy. It is certain that such will be the consummation.

Consider the flowers of a garden. Though differing in kind, color, form, and shape, yet, inasmuch as they are refreshed by the waters of one spring, revived by the breath of one wind, invigorated by the rays of one sun, this diversity increaseth their charm, and addeth unto their beauty. How unpleasing to the eye if all the flowers and plants, the leaves and blossoms, the fruits, the branches and the trees of that garden were all of the same shape and color! Diversity of hues, form and shape, enricheth and adorneth the garden, and heighteneth the effect thereof. In like manner, when divers shades of thought, temperament and character, are brought together under the power and influence of one central agency, the beauty and glory of human perfection will be revealed and made manifest. Naught but the celestial potency of the Word of God, which ruleth and transcendeth the realities of all things, is capable of harmonizing the divergent thoughts, sentiments, ideas, and convictions of the children of men.
