Jesus deliberately stays silent before Pilate and brings Isaiah to fulfillment. When he finally speaks from the cross he speaks from the Psalms of lament. God stays silent and allows the evil, further prodding skeptics to malign a heavenly Father who would commit what looks like savage child abandonment and abuse. However, in the mystery of trinity, the Jesus who silently suffered and died was God the Father himself, crucified for sin and suffering with those whose voices never get heard. Moreover, in the mystery of incarnation, the Son of God who suffered and died did so as a human being. Jesus who is one with God is also one with us. What happened to Him happened to us. Jesus died and took our sin and sorrow down with him. And then on Easter he rose to bring us back up. The apostle Paul realized this first hand: “I have been crucified with Christ, it is no longer I who live, but Christ who lives in me. The new life I live in the flesh I live by faith in the Son of God, who loved me.” And yet even in resurrection victory, Jesus still wears the telltale scars of his slaughter. He refuses to hide the evidence of his hurt. The Christ who lives in us is the crucified God.
This is a very difficult teaching.
