Those who refuse His mercy satisfy His justice in another way. Without His mercy, they cannot love Him. Without love for Him they cannot be 'justified' or 'made just'. That is to say: they cannot conform to Him Who is love. Those who have not received His mercy are in a state of injustice with regard to Him. It is their own injustice that is condemned by His justice. And in what does their injustice consist? In the refusal of His mercy. We come, in the end, to this basic paradox: that we owe it to God to receive from Him the mercy that is offered to us in Christ, and that to refuse this mercy is the summation of our 'injustice'. Clearly, then, only the mercy of God can make us just, in this supernatural sense, since the primary demand of God's justice upon us is that we receive His mercy.

In the cross of Christ God is taking man dead-seriously so that he may open up for him the happy freedom of Easter. God takes upon himself the pain of negation and the God forsakenness of judgement to reconcile himself with his enemies and to give the godless fellowship with himself.~ Theology of Play, p.33
