Purpose in life

In my constant effort of becoming a devout Muslim and performing dawa(propagating the truth of Islam), I have come across many insulting remarks perhaps since the people I have been conveying the message are either trapped in the false ideologies about Islam purposely injected in their minds by the enemies of Islam or due to some hidden agenda behind their ignorance. I am surprised on the naievety of the people in west who blindly believe in media lies and fail to understand and appreciate the truth and wisdom behind the faith of Islam which preaches peace to every one yet the evil actions of some individuals are purposely magnified and transformed in an effort of making the entire faith of Islam responsible for the same. Muslims have repetidely denied the association of Islam with any act of terror or misconduct but yet the enemies of Islam try their utmost effort not to convey the stories from muslim perspective and continue in their Islam bashing to spread constant rumors about Islam and its followers and yet people in the west who believe so much in their own freedom or expression are spoon fed the information that is beneficial only to the enemies of Islam.
