Nobody expected it!

The most radical of all perspectives on the cross will become clear to us if we reflect on the relation between the Old and New Testaments in this regard. To put it in the bluntest possible terms, no one expected a crucified Messiah. Isaiah 53 provided a clue of a suggestion of a hint of a prediction (“He was despised and rejected by men. . . . The Lord has laid on him the iniquity of us all,” 53:3, 6), but virtually no one understood this to refer to the Messiah of Israel until after the resurrection.—Fleming Rutledge, The Crucifixion, 90 (emphasis original)
