The question “Why did Jesus die?" is inseparable from the question "Why did they kill him?”
Persons who preach an exclusively transcendent Kingdom of God do not get themselves murdered. People who preach a Kingdom that is only a new relationship with God, or only “love,” or only “reconciliation,” or only “trust in God,” are not murdered. All these things may be legitimately regarded as elements accompanying the message of the Kingdom of God, but they alone do not explain Jesus’ death, and therefore they alone cannot be the central element of the Kingdom. The Kingdom of God must have had some bearing on the historico-social, not only the transcendent.
