"Extravagant Grace", "Grace Walk", "Grace is Greater"
I have just read 3 books on Grace. "Extravagant Grace" by Barbara Duguid, "Grace Walk" by Steve McVey, and "Grace is Greater" by Kyle Idleman. As a theological study, "Extravagant Grace" is probably the best one. On a practical level, relating it to my life, "Grace is Greater" is probably the best one.
I was disappointed in "Grace Walk". The author seemed to do a lot of judging of others who were not where he was at in his own spiritual walk. It came across as a child who just discovered something new that he/she thought no one else has ever seen. But the problems with that book are even deeper. It almost completely overlooked the problem of personal sin and humility before God.
"Extravagant Grace" was all about the problem of the continual daily struggle that a believer has with sin. I am sure that I am not the only one who found that some of what is said to be a little difficult to agree with. But it was said and opened the door for some great personal Bible study and prayer with God over the struggle.
"Grace is Greater" starts with the "more I recognize the ugliness of my own sin, the more I can appreciate the beauty of God's grace." This sets the tone of humility that is found throughout the whole book. This book applies grace to all of the brokenness of sin in our own life. It deals with the wounds of life.
I do recommend reading all 3 books for they all do have a lot of good things to say that are worth meditating upon and applying to your life.
