Here are several resources I found insightful from Daniel 10 related to matters it raises concerning the intersection of prayer and spiritual warfare:

  1. Angels and Prayer  – a very helpful sermon by John Piper
  2. Angels, Demons, and the Spiritual Dynamics of Prayer – another helpful sermon, this one by Sam Storms.
  3. Daniel 10 and the Notion of Territorial Spirits  – a bit more scholarly article by David Stevens.  Read this if you’re really interested in thinking more about territorial spirits!

Enjoy!
