In connection with the radio work ... he would suggest that the main consideration is to bring to the attention of the public the fact that the Faith exists, and its teachings. Every kind of broadcast, whether of passages from the Writings, or on topical subjects, or lectures, should be used. The people need to hear the word "Bahá'í" so that they can, if receptive, respond and seek the Cause out. The primary duty of the friends everywhere in the world is to let the people know such a Revelation is in existence; their next duty is to teach it.
