"The gospel is the A to Z of the Christian life. It is not only the way to enter the kingdom; it is the way to live as part of the kingdom. It is the way Christ transforms people, churches and communities." (page 9)
"The gospel - the message that we are more wicked than we ever dared believe, but more loved and accepted in Christ than we ever dared hope - creates a radical new dynamic for personal growth, for obedience, for love." (page 10)
It is not simply non-Christians, but also believers who need continually to learn the gospel and apply it ot their lives." (page 11)And that's just from the introduction!
