Jesus, dying on the cross was not about giving his life as a demonstration of power nor was it to save us from our so called sins. It was a demonstration that He was not his body or mind or anything else we all tend to identify ourselves with.
His closest disciples did not understand this either. This is why Peter came to his defense in the garden of Gethsemane and cut off the ear of the Roman soldier who was trying to apprehend Jesus. Peter wanted to defend the “man” He thought Jesus was, not who Jesus actually was. Peter, and so many others then and now, could not see who Jesus was outside the “man” he thought him to be. He only saw the “man” and thought the “man” was endowed with special powers and that he must defend Jesus, as “the man” Peter “thought” him to be.
Jesus was never able to convince anyone that He was not his body; that He was not the “object” others had created him to be. His whole ministry was a demonstration of his own awareness that he was completely unidentified with anything in the world. His crucifixion was a profound and vivid example of that. Death did not matter to him. Not because we “rise again,” but because what WE truly are never dies! Who we are never dies and Jesus imparted that message one last time by allowing himself to be killed as a demonstration that he would continue on just as each of us will continue on.
We will never “fail” in this life because this life is not anywhere near what we are in eternity. Detach from the body, discover who resides within and nothing in human experience will ever be able to take from you anything that actually does matter.
