Today: [Daniel 10] Spiritual Warfare Lessons in the Book of Daniel. In Daniel chapter 10 the prophet Daniel is in the midst of a 21 day fast when an angel, apparently Gabriel appears to him once again. The angel explains that Daniel’s prayers were heard weeks before, but there was resistance in the heavens by the demonic prince of Persia. The angel goes on to explain that he only broke through to Daniel after the angel Michael comes to his assistance. This all opens to us a deeper understanding of spiritual warfare and the activity of angels in connection to our prayers.
