There is a lot being said and written about today in the evangelical world concerning the connection between evangelism and "social action."
Almost two years ago, Tony Payne wrote three posts on this subject which I found insightful and biblically faithful (though we may have some slight disagreement on 2 Peter 3, I agree with his conclusions in point #3 of post 2). If you have some time on this rainy weekend, check them out and let me know what you think:
Part 1: What is the relationship between evangelism and social action?
Part 2: How does social action relate to the Last Day and the new creation?
Part 3: What does social action look like for the Christian?
