If we wish for the world to listen to our message we must first be someone. One of the reasons people listen to Jesus is that he was someone.
Simply being someone is, of course, not enough we must also have something of value to say. The world will not listen to us, however, if we are not people who are something unique and beautiful.
Once we are seen as different in a way which can be appreciated then what we have to say will be considered. Our character is of the most importance in how what we say is viewed.
