The imagery this brings to mind is filled with pathos. The creator of the universe tied. This image of God and Man having his hands tied and unable to do anything or defend himself without causing a violence to order.
A reflection of this is that Jesus accepts the situation. He stands there both as me and Him with both of us having our hands tied.
Why cant he do anything? because we have bitten of the tree of knowledge. We have demanded "choice" and now in this freedom which He gives as part of our contract for being human He cannot intervene.
At times the human creature cries "why Lord?" why didnt you stop him/he" and to this question he shows His hands tied and He is rendered helpless. We have chosen choice.
