What happens if we actually believe what we preach? What happens if we dare to trust that the economic Trinity is the immanent Trinity? Robert Jenson does not shirk. He insists we have to venture a claim as bracing as this: God’s unity with himself was at stake in the cross. What if Pharaoh had won? What if Jesus had succumbed to the Tempter’s lure? What if Pilate’s stone had remained fixed in the mouth of the tomb? If we say those outcomes were metaphysically impossible, then we have simply gutted the gospel.
