The “theme” we should “pursue in our efforts to deepen in the Cause”

Dearly loved friends, this is the theme we must pursue in our efforts to deepen in the Cause. What is Bahá'u'lláh's purpose for the human race? For what ends did He submit to the appalling cruelties and indignities heaped upon Him? What does He mean by "a new race of men"? What are the profound changes which He will bring about? The answers are to be found in the Sacred Writings of our Faith and in their interpretation by 'Abdu'l-Bahá and our beloved Guardian. Let the friends immerse themselves in this ocean, let them organize regular study classes for its constant consideration, and as reinforcement to their effort, let them remember conscientiously the requirements of daily prayer and reading of the Word of God enjoined upon all Bahá'ís by Bahá'u'lláh.
