O SON OF DUST! Verily I say unto thee: Of all men the most negligent is he that disputeth idly and seeketh to advance himself over his brother. Say, O brethren! Let deeds, not words, be your adorning.
(Baha'u'llah: Persian Hidden Words, Page: 5)
O CHILDREN OF ADAM! Holy words and pure and goodly deeds ascend unto the heaven of celestial glory. Strive that your deeds may be cleansed from the dust of self and hypocrisy and find favor at the court of glory; for ere long the assayers of mankind shall, in the holy presence of the Adored One, accept naught but absolute virtue and deeds of stainless purity. This is the day-star of wisdom and of divine mystery that hath shone above the horizon of the divine will. Blessed are they that turn thereunto.
(Baha'u'llah: Persian Hidden Words, Page: 69)
Tell him, no one in this world can claim any relationship to Me except those who, in all their deeds and in their conduct, follow My example, in such wise that all the peoples of the earth would be powerless to prevent them from doing and saying that which is meet and seemly. (Baha'u'llah: Excellence in All Things, Page: 367)
Be generous in prosperity, and thankful in adversity. Be worthy of the trust of thy neighbor, and look upon him with a bright and friendly face. Be a treasure to the poor, an admonisher to the rich, an answerer of the cry of the needy, a preserver of the sanctity of thy pledge. Be fair in thy judgment, and guarded in thy speech. Be unjust to no man, and show all meekness to all men. Be as a lamp unto them that walk in darkness, a joy to the sorrowful, a sea for the thirsty, a haven for the distressed, an upholder and defender of the victim of oppression. Let integrity and uprightness distinguish all thine acts. Be a home for the stranger, a balm to the suffering, a tower of strength for the fugitive. Be eyes to the blind, and a guiding light unto the feet of the erring. Be an ornament to the countenance of truth, a crown to the brow of fidelity, a pillar of the temple of righteousness, a breath of life to the body of mankind, an ensign of the hosts of justice, a luminary above the horizon of virtue, a dew to the soil of the human heart, an ark on the ocean of knowledge, a sun in the heaven of bounty, a gem on the diadem of wisdom, a shining light in the firmament of thy generation, a fruit upon the tree of humility.
(Baha'u'llah: Gleanings, Page: 285)
The essence of faith is fewness of words and abundance of deeds; he whose words exceed his deeds, know verily his death is better than his life. (Baha'u'llah: Tablets of Baha'u'llah, Page: 156)
…O people of God! Do not busy yourselves in your own concerns; let your thoughts be fixed upon that which will rehabilitate the fortunes of mankind and sanctify the hearts and souls of men. This can best be achieved through pure and holy deeds, through a virtuous life and a goodly behavior. Baha'u'llah: Gleanings, Page: 94
Although a person of good deeds is acceptable at the Threshold of the Almighty, yet it is first "to know," and then "to do." Although a blind man produceth a most wonderful and exquisite art, yet he is deprived of seeing it. Consider how most animals labor for man, draw loads and facilitate travel; yet, as they are ignorant, they receive no reward for this toil and labor. The cloud raineth, roses and hyacinths grow; the plain and meadow, the garden and trees become green and blossom; yet they do not realize the results and outcome of all these. The lamp is lighted, but as it hath not a conscious knowledge of itself, no one hath become glad because of it. Moreover, a soul of excellent deeds and good manners will undoubtedly advance from whatever horizon he beholdeth the lights radiating. Herein lies the difference: By faith is meant, first, conscious knowledge, and second, the practice of good deeds.
