It has to begin with you

When you say that it is possible to challenge the false, then your life has to be a proof of that challenge. And when you come up to people not only with your words but with the backing of your life, then people appreciate it, then you are credible. Otherwise, you are just talking.

So, it has to begin with you. First of all, you have to be that who can be the Messenger; who can be the Teacher.
