Religious Music

What is the difference between Bob Marley's music and Christian rock? During class one big difference that was brought up was the styles of music. Reggae and rock are clearly stylistically different. The idea that Marley's music is directed more pointedly at the people than at praising God was also brought up.

The biggest difference I see, however, is that Marley seems to focus much more on historical events than Christian rock does. Granted, I am no expert on Christian rock, but from what I have heard, the lyrics consist much more of concepts surrounding faith and beliefs whereas Marley's music focuses on historical people and events, tying them into the main message of his music.
