Given that we have been talking about building a culture of faithfulness, I would like to draw your attention to the latest edition of the 9Marks eJournal. 9Marks posed this question, "Does God call the church to transform the culture?" and got a variety of pastors and theologians to respond. I would particularly draw your attention to what I felt were the best contributions to the discussion.
"Transforming Culture with a Messiah Complex" by Michael Horton.
"What Does Scripture Say about the Poor?" by Steve Boyer and the Capitol Hill Baptist Church elders.
"Countering Ageism" by Owen Strachan.
