Justin Taylor at the Gospel Coalition has provided a free chapter from the new book  Paul’s Missionary Methods: In His Time and Ours. The chapter is entitled “Paul and Spiritual Warfare” written by Craig Keener. If you aren’t familiar with Keener, he is one of the top New Testament scholars in the world as well as a genuine Charismatic Christian (which gives him bonus points in my book). In this chapter he covers the armor of God in Ephesians 6, spiritual warfare in Ephesians, and Paul’s power encounters in Acts. Then he deals with the implications today. Well worth checking out.
