''Why is it better for me to forgive someone and take on the cost of that forgiveness myself?''In his new book, renowned pastor and author Timothy Keller grapples with this thorny question: why we should forgive those who hurt us. It is the heart of the gospel, but it''s not solely important on a religious level; the matter of forgiveness has a huge impact on social and cultural levels, in terms of how we deal with the people, and problems, in our lives. What is it like to carry around resentment and judgement, and what does it cost us to do so - as against the very real personal cost of extending forgiveness to others? These are issues that matter on a daily level, as well as a spiritual one.Writing with his trademark wisdom and deep reliance on the Bible, Keller helps readers think about these questions in an way that will help them rethink their lives, in ways that point to Jesus showing us how to live in the world - and how we can live in a spirit of forgiveness.
