Finally, I hope that in Chicago the friends may become united and may illumine that city, for therein the dawn of the Cause appeared, and in this lieth its preference over other cities. Therefore it must be held in respect; perchance it may, God willing, be freed from all spiritual afflictions, and may attain unto perfect health and become a centre of the Covenant and Testament. 71: O THOU BELOVED MAIDSERVANT OF GOD! THY LETTER ... O thou beloved maidservant of God! Thy letter was received and its contents revealed the fact that the friends, in perfect energy and vitality are engaged in the propagation of the heavenly teachings. This news hath caused intense joy and gladness. For every era hath a spirit; the spirit of this illumined era lieth in the teachings of Bahá’u’lláh. For these lay the foundation of the oneness of the world of humanity and promulgate universal brotherhood. They are founded upon the unity of science and religion and upon investigation of truth. They uphold the principle that religion must be the cause of amity, union and harmony among men. They establish the equality of both sexes and propound economic principles which are for the happiness of individuals. They diffuse universal education, that every soul may as much as possible have a share of knowledge. They abrogate and nullify religious, racial, political, patriotic and economic prejudices and the like. Those teachings that are scattered throughout the Epistles and Tablets are the cause of the illumination and the life of the world of humanity. Whoever promulgateth them will verily be assisted by the Kingdom of God. The President of the Republic, Dr. Wilson, is indeed serving the Kingdom of God for he is restless and strives day and night that the rights of all men may be preserved safe and secure, that even small nations, like greater ones, may dwell in peace and comfort, under the protection of Righteousness and Justice. This purpose is indeed a lofty one. I trust that the incomparable Providence will assist and confirm such souls under all conditions. 72: O THOU TRUE FRIEND! READ, IN THE SCHOOL OF GOD, THE ... O thou true friend! Read, in the school of God, the lessons of the spirit, and learn from love’s Teacher the innermost truths. Seek out the secrets of Heaven, and tell of the overflowing grace and favour of God. Although to acquire the sciences and arts is the greatest glory of mankind, this is so only on condition that man’s river flow into the mighty sea, and draw from God’s ancient source His inspiration. When this cometh to pass, then every teacher is as a shoreless ocean, every pupil a prodigal fountain of knowledge. If, then, the pursuit of knowledge lead to the beauty of Him Who is the Object of all Knowledge, how excellent that goal; but if not, a mere drop will perhaps shut a man off from flooding grace, for with learning cometh arrogance and pride, and it bringeth on error and indifference to God.
