He approves of your desire to teach the principles of the Faith through radio. But he urges you to do all you can to always, however small the reference you are able to make to it may be, clearly identify or associate what you are giving out with Baha'u'llah. The time is too short now for us Baha'is to be able to first educate humanity and then tell it that the Source is this new World Faith. For their own spiritual protection people must hear of the name Baha'i -- then, if they turn blindly away, they cannot excuse themselves by saying they never even knew it existed! For dark days seem still ahead of the world, and outside of this Divine Refuge the people will not, we firmly believe, find inner conviction, peace and security. So they have a right to at least hear of the Cause as such!
