The Way to True Unity for All the Followers of Jesus
Short thoughts: In some ways Costly Love could be a short article or talk. But this is not a short article or talk because the Church as a whole really seems to have misunderstood what love is and why it is important. That requires a ground up inspection of what love means, why love is not just some aspect of theology or God's character, but a central concern. And then the implications of that love. John's perspective is strongly shaped by his work in what he calls ‘missional ecumenism'. That work is drawing the broad church into greater relationship, understanding, and appreciation of itself.
Like many others good books on aspects of Christianity, Costly Love is a book about discipleship. Discipleship is about transformation long term, not data processing. Information and theology can help us understand God and others and love more deeply, but theology without praxis is never really full Christianity. Love is not something that can only be thought about, it has to be practiced with actual people.
I listened to the audiobook and there were three small audio editing issues that were each only a few seconds long. They were not significant, but they were present.
