Grunge is out of the way for most rock genres to be combined with it even country music. However the possibility of Grunge and Christian Rock joining forces seems the most plausible scenario. Already a metal band made a first album a throw between Christian and Grunge. The reasons for this to be possible is:

1. Grunge has strong humility in character throughout songs. Christianity teaches the importance of humility that the most true Christians have to have the characteristics of
Jesus to be considered a true Christian.

2. Grunge reaches out to people where it seems other genres don't do it as much. Christianity considers it paramount to reach out to people not of the faith and even to those questioning their faith. A true Christian has a desire to heal others and comfort those in need of it.

3. Grunge doesn't try to impress the worldly perspective of individualism (which is ironic since they believe in a communism of person hood) thus more a desire to not conform. Christianity teaches to live in the world but be not of it, that you will find yourself (even your true identity) by not giving in to the whims of the world, God expects us to have individualism of character and person hood as we try to emulate Jesus. God doesn't want us to be robots, only Satan wants robots!

4. Grunge acknowledges short comings and issues and also that the world is full of ignorance especially a lack of realism. Christianity says the world is full of sin and indifference having no desire to change its ways, they believe that even as we are bound to the shortcomings and evils of the world that we must strive to be better than that.

There you have it, Grunge and Christian rock to me is a match made in heaven.
