"Why some prayers go unanswered?"
Daily Broadcast (currently a study on Ephesians #39)
When I first started as an intercessor and than prayer warrior, Kay Arthur's book on PRAYER was one of my first... "Lord, Teach Me to Pray" and since then she has expanded and updated and this link is to her most current ...in 28 days (4 wk. study) and then her other book, "Lord, Is it Warfare?" Whatever Kay teaches, she does with depth as well as clarity and simplicity from God's Word and her own personal experiences. I was blessed greatly by reading her books and now by watching/listening to her teach.
