In The Audacity of Peace, Scot McKnight sketches a peace ethic, or a peace witness, that embraces the embodied self-denial of Jesus to the point of the cross, which through the resurrection is vindicated by God. As such, a peace ethic volitionally and communally participates in the cruciform pattern of the life of Jesus. Through the power of God's grace and the indwelling Spirit of God, the participant in the way of Jesus is transformed into a Christoform life. A peace ethic is a lived theology whose discerning witness transcends the specific principles and ideas of that theology.

In the My Theology series, the world's leading Christian thinkers explain some of the principal tenets of their theological beliefs in concise, pocket-sized books.
