The suffering servant is vey human.  If you take the Gospels together, you can place the passage in John where Jesus gives care of his mother to the beloved disciple right before he call out in despair.  In this act, he abandons his divine origins, which he originally learned from his mother (and she kept all these things in her heart) by severing ties with he a his imminent death.  Likewise, he tells John (or Lazarus), to care for Mary, not to go out and baptize all nations, thus abandoning his Church as well.  Total emptiness, just like that of the sinner in a world of blame.  We know this is the sacrificial act because after it occurs, John states that Jesus took the fruit of the vine (I thirst), thus signaling the beginning of the Kingdom of God.
