Graham A. Cole in God the Peacemaker: How Atonement Brings Shalom:
The God of the Bible is the righteous God of holy love. The trouble is, however, that we have become paradoxically the glory and garbage of the universe. Our great need is peace with God, and not just with God but also with one another.
There is no shalom, however, without sacrifice. Peace is made through the blood of the cross. The atoning life, death and vindication of the faithful Son bring shalom by addressing the problem of sin, death the devil and wrath definitively. Eschatologically speaking, the realization of the triune God’s reconciling project will see God’s people in God’s place under God’s rule living God’s way enjoying shalom in God’s holy and loving presence to God’s glory.
The broad notion should humble us at the thought of a righteous God of holy loving purpose who, in love, has never abandoned his wayward creatures but in a plan of rescue has begun to reclaim the created order and will in the end restore creation to himself and to his glory. Love is the motive, glory the goal. The narrow one brings us to Christ and his cross. He is the linchpin of the plan. We are brought to a real Christ, to a real cross, to a real cost.
