Good books for training and warfare:
Prayers that Rout Demons and Break Curses, by John Eckhardt
Demolishing Demonic Strongholds, by Moris Cerullo
A More
Excellent Way, by Dr. Henry W.
Wright
A Women's Guide to Spiritual Warfare, by Quin Sherrer & Ruthanne Garlock
*Larson's Book of Spiritual Warfare, by Bob Larson
*Dealing with Demons, by Bob Larson
*These two books cover very heavy topics concerning the works of darkness, and I do not recommend them for a child under the age of 13. I would encourage parents to read them first and determine if they are a good fit for your child.
