Mark 9:7-10 (NIV)
Then a cloud appeared and enveloped them, and a voice came from the cloud: “This is my Son, whom I love. Listen to him!”  Suddenly, when they looked around, they no longer saw anyone with them except Jesus.  As they were coming down the mountain, Jesus gave them orders not to tell anyone what they had seen until the Son of Man had risen from the dead.  They kept the matter to themselves, discussing what “rising from the dead” meant.
So the voice of God…
We moderns do not often get to hear God that way–out of the heavens, direct-like. We don’t need to. We have His voice in the Bible and in the wind. His power and purpose in the night sky.
I like the timing of this narrative. The disciples are already awed by Jesus. The voice of the Father is not the emotional center of this story. His injunction is a corroborating authority.
Jesus stands alone.
Through most of the Bible he mutes the physical reality of his deity to do an unbearable job.
Why this story? Why so quiet?
The road of faith is bewilderingly painful. It helps to keep our glimpse of God at the center of our minds and hearts. It helps to know who he really is. It helps a great deal to see him.
Light on the water.
