Having gone through the Truth Project this past summer, I have been looking forward to hosting a group in my home. This is coming to fruition on October 12th (Columbus Day, what an irony) as our church will begin various home groups of the Truth Project.
If you don't know what the Truth Project is, go visit their web page (truthproject.org). In my opinion, it is the best new material to come out since Francis Schaeffer's work in the 50s and 60s. It is a phenomenally well-done look at the influence of culture on the values of the church, and churchmembers (believers) in general. I highly recommend it to anyone who believes in Christ and doesn't fully understand the nature of the culture wars around them (attacks on the church, attacks on morality, attacks on marriage and the family, etc.).
Find a group in your area and go. It'll be worth it.
