The second birth spoken of here comes from the resurrection and from nothing else. Something in you has lain asleep, buried in the body as a man lies buried in a tomb, and one day it wakes inside your own skull. That awakening is the resurrection of Christ within. It causes the birth from above. The father being blessed is your own imagination, the power that raised you. Once that power stirs and a person comes to himself, the lively hope named here stops being a wish. It becomes the settled expectation of someone already lifted out of the grave. He does not hope his way toward a better life. He stands in a life that death can no longer reach.
