Hmm …

… Did Jesus Bungle the Resurrection? – Mark Vernon.

Better is another view that runs through the tradition, sometimes called the sign or exemplary theory. On this understanding, sacrifice is about cultivating a sacrificial attitude: the routine letting go and offering up of life.
It’s a rhythm of life that echoes the resurrection appearances. It fosters the inner habit, perception from within, and re-orientates the sacrificer to the kingdom, and lets them drop into the life of God.
It becomes a way of cultivating the detachment that enables the individual to be in the world but not entangled by the fears and distractions of the world. It makes sense of what Paul wrote to the Colossians. “Set your mind on things above, not on things on earth. For you died, and your life is hidden with Christ in God.”
