The World Magazine blog had an interesting post about abortion and urban ministry this week at http://online.worldmag.com/2008/09/24/abortion-rate-at-30-year-low/. The post emphasizes the need to reach "da hood" and "the trailer park" in efforts to reduce the abortion rate. (Just a side comment: Having grown up in a trailer park, I did not even realize at the time that people might look down on me for where I lived.)
At the Contact Church, Mary Lasarsky leads a great ministry for pregnant girls and young women as a part of the urban ministry. More information can be found at www.contactchurch.net/contact_life. She has been making a difference for years now.
