See The Empty Day for my personal take on Jesus' passion.
He is just there. A historical person, demonstrating in the flesh, through the stories about him, all that a human being is capable of doing when in full relationship with God.
What, then, was so powerful for Jesus’ disciples—after their flight and betrayal and denial of him—that they could know him to be alive for them again?
It was the simple, bone-deep realization that they still experienced the kinship with God which Jesus had enabled them to know before his death.
That kinship was not broken, cannot be broken.
“Jesus knows, God knows. Just wake up and follow him again. That’s all we can do.”
And so it is.
