Greg McKinzie, debunking the "God turned his back on Jesus" argument:
The cross is the moment when God With Us screams out the meaning of his identity, not the moment when God With Us suddenly becomes God Left Us. In this last, most terrible moment, when Life takes death into himself, he stays. This is the very meaning of God’s faithfulness. The Father does not abandon when things are their ugliest. There is no compulsion in the divine being that makes him unable to bear the sight of sin or forces him to turn his back. He is not that father. He is not that god.
Think about it. We say "the cross" is the epicenter of God's plan for the salvation of humanity. Then we say that God abandoned Jesus on the cross. Was God completely absent at the fulfillment of God's will?
You can't have it both ways.
