The cornerstone of the foundation of all Baha'i activity is teaching the Cause. As 'Abdu'l-Baha has categorically proclaimed in His Will and Testament, "the guidance of the nations and peoples of the world" is "the most important of all things," and "Of all the gifts of God the greatest is the gift of Teaching.
The friends likewise are in varying degrees aware of the repeated exhortations found in the Writings of our Faith that divine confirmations are dependent upon the active pursuit of the teaching work. In the words of the beloved Master, "confirmations from the unseen world are encompassing all those who deliver the divine Message." He further states, "should the work of teaching lapse, these confirmations would be entirely cut off, since it is impossible for the loved ones of God to receive assistance unless they teach."
