To satisfy justice, God came down. Not Allah; Yahweh. Not Mohammed; Jesus. God stepped out of heaven and dwelt among us—“A body you prepared for me”—and said to the Father, “Take me instead.” That was the trade. The trade took place on a small outcropping of rock outside the walls of ancient Jerusalem. It was called Golgotha, the place of the skull. We know it as Calvary, the place of the cross.
