He fully approves the idea of holding study classes, for the deeper the friends go in their understanding of the teachings the more firm and steadfast they will become and more unwavering in their support of the institutions of the Faith. Books such as the Iqán, Some Answered Questions and The Dawn-Breakers should be mastered by every Bahá'í. The first two books will reveal the significance of this divine revelation as well as the unity of all the Prophets of old. The last book will show how the Faith was ushered into the world and how its early adherents heroically faced martyrdom and suffering in their desire to establish the Cause throughout the world. Knowing the life of those heroes will create in us the urge to follow their footsteps and achieve the same.
