Transforming Grace, Living Confidently in God's Unfailing Love by Jerry Bridges and published by Navpress.
Funny how the riches of God's grace seem to run out the moment we're saved! From then on, we tend to base our relationship with him on our accomplishments rather than on his unconditional acceptance. In "Transforming Grace" Bridges addresses the "performance treadmill" and what can happen when we forget how generous God's grace is. Come back to the love that's waiting for you, and learn to trust His grace every day.
