I recommend the following as particularly good nourishment for a healthy Christian life…
They are, in no particular order:
Anything by Frank Viola or Leonard Sweet: http://frankviola.org/
You can read my review of Frank’s From Eternity to Here on this blog here: http://thedevotionalden.com/probably-the-best-book-ever-written-on-the-body-of-christ/
Anything by Watchman Nee, particularly The Normal Christian Life; Sit , Walk, Stand; The Spiritual Man. Amazing teaching.
Anything by Andrew Murray. My favorite: With Christ in the School of Prayer. Deep and insightful.
Anything by contemporary novelist Bill Myers. I particularly like his teen series: Dark Power Collection; Deadly Loyalty Collection; Invisible Terror Collection and Ancient Forces Collection (total 12 novelettes), and his nonfiction Dark Side of the Supernatural is a good read for anyone tempted to dabble even slightly in the occult. And his full-length novel The Face of God.
Anything by A.W. Tozer: My favorites: The Root of Righteousness; Reclaiming Christianity: A Call to Authentic Faith; and The Pursuit of God.
Hal Lindsey’s: Combat Faith and his later more lengthy treatment of the subject Faith for Earth’s Final Hour. Powerful teaching on practical faith.
I reviewed both books here: http://thedevotionalden.com/is-your-faith-up-to-the-task-2/
I’m also a fan of Oswald Chambers, his My Utmost for His Highest in particular. I am reading his Biblical Psychology now, and I am not only enjoying it but also I find it to be a profound and insightful teaching on our spirit and soul and body.
For solid help in interpreting your Bible, Kay Arthur. I particularly like her Discover the Bible for Yourself, as well as her book on prayer: Lord, Teach Me to Pray in 28 Days.
