The following books are recommended:
Pure Grace: The Life Changing Power of Uncontaminated Grace. Clark Whitten
We have been freed from sin, and we cannot be transformed by trying to manage sin by human effort.
The Rest of the Gospel: When the Partial Gospel Has Worn You Out. Dan Stone and David Gregory
We are called to be saints, not sinners. We live "above the line," setting our thought on things above in the unseen realm, where we have been declared perfect, rather than "below the line," setting our thoughts on things below in the seen realm, where we are in the natural -- "confessing" (i.e., declaring) ourselves to be sinners.
Transformation: The Heart of Paul's Gospel. David A. DeSilva and Michael F. Bird
Paul's gospel is one of transformation and not one of justification - then looking for something to do so we might keep (maintain) our justification.
The Good and Beautiful Community: Following the Spirit, Extending Grace, Demonstrating Love. James Bryan Smith
The church is Christians in unity, serving and following Christ, and not individuals in isolation.
Creation: The Apple of God's Eye. Justo L. Gonzalez
This relatively short book touches on the "Who" and "Why" of creation, which are the questions that the Bible addresses. God's love is shown in the creation. Fretting about "how" God did the creation is way down on the list of questions with eternal significance.
Also, books by Andrew Farley:
Relaxing With God: The Neglected Spiritual Discipline.
The Naked Gospel: Truth You May Never Hear in Church.
God Without Religion: Can It Really Be This Simple?
Heaven is Now: Awakening Your Five Spiritual Senses to the Wonders of Grace.
These (and other) books by Andrew Farley and his radio program (see free app "AFM" at app store) focus on the grace and forgiveness from God and on how we nevertheless continue to try and earn our forgiveness from "the Law" while all the time denying we do that.
The authors of these publications -- books, blogs, A/V presentations, etc. -- explain spiritual concepts much more clearly using a less confrontational-sounding approach.
