In an incomprehensible reversal of all righteous and pious thinking, God declares himself guilty to the world and thereby extinguishes the guilt of the world. God himself takes the humiliating path of reconciliation and thereby sets the world free. God wants to be guilty of our guilt and takes upon himself the punishment and suffering that this guilt brought to us. God stands in for godlessness, love stands in for hate, the Holy One for the sinner. Now there is no longer any godlessness, any hate, any sin that God has not taken upon himself, suffered, and atoned for. Now there is no more reality and no more world that is not reconciled with God and in peace. That is what God did in his beloved Son Jesus Christ. Ecce homo--see the incarnate God, the unfathomable mystery of the love of God for the world. God loves human beings. God loves the world--not ideal human beings but people as they are, not an ideal world but the real world.
-- Dietrich Bonhoeffer, God Is In The Manger
