The God and the Gospel of Righteousness

For too many the heart of the gospel is that God is love and that he loves everybody unconditionally. Yet neither Jesus nor his apostles ever preached like that. They seem to have thought that the world needed to know about his righteousness and his willingness, even his eagerness, to share that with us. This is because he is determined to have a universe in which there is no unrighteousness whatever. Why don't we think that is good news
