I could write a little blurb on what I think that Christian interaction with politics should be on the basis of this two kingdom perspective but Michael Horton & The White Horse Inn has once again tackled the topic exceptionally well. Check it out:
Some good articles concerning Christianity & Politics:
Beyond Culture Wars, by Michael Horton
Christians & Political Action, an Interview with Michael Cromartie
Religion & Politics, A Roundtable Discussion with William Bennett, Michael Horton, Os Guinness, Cal Thomas, & Jim Wallis
Also, be sure to check these helpful books:
Also, here some of my other posts on Politics.
About The White Hosre Inn:
By the way...The White Horse Inn is a nationally syndicated radio talk show hosted by Michael Horton, Rod Rosenbladt, Kim Riddlebarger and Ken Jones. On the air since 1990, the show features a regular roundtable discussion of Christian theology and apologetics. I love this program and highly reccommend, not only this current program on politics, but all their programs! WHI gets you to think and challenges you to "know what you beleive and why you beleive it!" So, it's good stuff!
