108. This is to say that Messenger does not merely convey the message but is sent to reform human life in accordance with it. He has to apply the principles of the message to the circumstances of human beings and has himself to demonstrate practically those principles. Moreover, he has to remove the misunderstandings of those people who try to listen to and understand his message. Besides this, he has to organize and train the believers to create a society based on the teachings of his message. He has to struggle against those who reject and oppose his message in order to subdue those powers that are bent upon corruption, and bring about that reformation for which Allah has sent His Messenger. As all these things have to be done in a society of human beings only a human Messenger can perform the mission. If an angel had been sent as a Messenger, the most he could have done was to convey the message, for he could not live among human beings and share their life and problems in order to reform them. It is thus clear that a human Messenger only could be suitable for this purpose.
