Grace and I have personally benefitted from the following books; they are easy to read and are among the best in their areas of instruction. We have recommended these books many times over the years and have purchased many copies for our friends. Spiritual Disciplines Spiritual Disciplines for the Christian Life (NavPress, 1991) by Donald S. Whitney Christian Living Desiring God: Meditations by a Christian Hedonist (Multnomah, 2003) by John Piper Keep in Step with the Spirit: Finding Fullness in Our Walk with God (Baker, 2005) by J. I.

Also great for personal reading and note-taking is the ESV Journaling Bible, patterned after the Moleskine.
