Preachers of LA: Watch Preachers of LA preach off, on the Arsenio Hall show

A preacher is a person who delivers sermons or gives homilies, generally on religious topics, although one can also preach any of the components of any worldview or philosophy. Some see a preacher as distinct from a theologian by focusing on the communication rather than the development of doctrine. Others see preaching and theology as being intertwined. Preaching is not limited to religious views, but it extends to moral and social world-views as well.

Preachers are common throughout most cultures. They can take the form of a Christian minister on a Sunday morning, or an Islamic Imam. A Muslim preacher in general is referred to as a Da’ee, while those giving sermons on a Friday afternoon are described as a khatib. The point of Christian preaching is to convince the hearer of their need of salvation through the gospel of Jesus Christ. (cf Epistle to the Romans 4:25) In the Book of Acts, Saint Paul travels widely to preach ‘God‘s message’.(13:5)(wikipedia)
