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 to 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. We pray God to protect thee from the heat of jealousy and the cold of hatred. He verily is nigh, ready to answer.

Gleanings from the Writings of Baha’u'llah, p. 285

This particular quote has been one of my favorites as it is comprised of small commands or directives on how to live one’s life.  In many ways, it reminds me of the Beatitudes from Jesus’s Sermon on the Mount:

¹Now when he saw the crowds, he went up on a mountainside and sat down. His disciples came to him, ²and he began to teach them saying:
³“Blessed are the poor in spirit,
      for theirs is the kingdom of heaven.
⁴Blessed are those who mourn,
      for they will be comforted.
⁵Blessed are the meek,
      for they will inherit the earth.
⁶Blessed are those who hunger and thirst for righteousness,
      for they will be filled.
⁷Blessed are the merciful,
      for they will be shown mercy.
⁸Blessed are the pure in heart,
      for they will see God.
⁹Blessed are the peacemakers,
      for they will be called sons of God.
¹⁰Blessed are those who are persecuted because of righteousness,
      for theirs is the kingdom of heaven.

¹¹“Blessed are you when people insult you, persecute you and falsely say all kinds of evil against you because of me. ¹²Rejoice and be glad, because great is your reward in heaven, for in the same way they persecuted the prophets who were before you.

~ Matthew 5:1-12, NIV

The Divine Messengers have been sent down, and their Books were revealed, for the purpose of promoting the knowledge of God, and of furthering unity and fellowship amongst men.

~ Baha’u'llah, Epistle to the Son of the Wolf, p. 12

Baha’is believe that the founders of each of the major religions were Divine Messengers of the same God.  We believe in only one God, and only one true religion.  These manifestations were able to give us texts—from the Zand-i-Avesta to the Qur’ān and from the Tripiṭaka to the New Testament—these books were meant to provide us with instructions on how to create a more unified and peaceful world.  Each one revealed to us more of God’s message.
