Not Cheap Grace
"When [Israel] came to the nations, wherever they came, they profaned my holy name, in that people said of them, “These are the people of the LORD, and yet they had to go out of his land.” But I had concern for my holy name, which the house of Israel had profaned among the nations to which they came. Therefore say to the house of Israel, Thus says the Lord GOD: It is not for your sake, O house of Israel, that I am about to act, but for the sake of my holy name, which you have profaned among the nations to which you came. And I will vindicate the holiness of my great name, which has been profaned among the nations, and which you have profaned among them. And the nations will know that I am the LORD, declares the Lord GOD, when through you I vindicate my holiness before their eyes. (Ezek. 36:20–23)
I will establish my covenant with you, and you shall know that I am the LORD, that you may remember and be confounded, and never open your mouth again because of your shame, when I atone for you for all that you have done, declares the Lord GOD. (Ezek. 16:62–63)
When I read these texts and Jonathan Edwards’s reflection on them, I felt like I was in a different world of God-centered grace than the world of my own century (the twentieth, at the time). I still feel that way. That’s one of the reasons I am writing this book. As shocked as most modern people feel in being told that they should “be confounded” and have their mouths shut—not by God’s righteous terror but by his atoning mercy—the fact is, this is profoundly right, and the brokenhearted soul who has been healed by grace knows it. It is cheap grace, not genuine grace, that thinks life in Christ is without remorse for past sin and for remaining corruption."
