"God's being gives meaning to God's action". So said Gustavo Gutiérrez. If we grasp what it means to say that God is just, we learn what justice really looks like. If we understand how divine anger works, we understand how we can be fruitfully angry. Understanding who God is, is not an 'ivory tower' activity, but one which helps us to better grasp of both Christian worship and Christian action. An accessible introduction to the doctrine of God, Only God Will Save Us demonstrates for students, ordinands and Christian practitioners how a theological articulation of the nature of God can drive and refine Christian action in the world.
