As you might have fathomed from other comments of mine, I do not buy the doctrine that God needed the sacrifice of Jesus to make him forgive us for Adam and Eve’s problem of puberty, like you would not get satisfaction from the death of anyone because your children rejected your authority over them. When God states that they are going to become mortal, when eating from that tree as a sign of realizing their self, it is not a threat but a statement of fact. Thus in my eyes, when Jesus died for us, he did not do it to make God happy but to demonstrate that one can endure the worst of the suffering if one trusts God and accepts his authority. That he took the sting out of death refers to him being the evidence of faith in showing us that we can live like him in God and live in every heart that has been touched by Gods love. To me this is not about material immortality as only a fool would want it to be about that. Material immortality is a wish of the selfish. Whoever loves is happy to give their material existence for thyselves to allow them to live through the metamorphosis of becoming human to pass into the next dimension. As much as some might dislike Harry Potter, Dumbledoor expresses it so nicely in the thoughts of his friend Nicholas Flamell: "“to the well-organized mind, death is but the next great adventure”, a bit like Peter Pan.
Our fear of death and all the suffering involved comes from our self-materialisation and the inability to imagine an existence with God that is uncoupled from our material existence. To suffer death is the lack of faith in God and the world to come. If we manage to sing a psalm praising God when going into death, like Jesus did, we can also demonstrate that death has no power over us. Jesus had authority over death as he did not demand authority over it, as those who demand authority over something only show not to have it.
The whole point of the cross is that Jesus did not die and showed us that the physical death is not the end of existence. I understand that not sacrificing innocent humans to God was the bit that distinguished the Jews from their contemporary cultures thus to look at the death of Jesus as the sacrifice of God to God himself makes no sense at all. To die for me so I can see that one can endure any suffering when with God is a much more coherent interpretation of Jesus on the cross. He did not go through all that suffering to please God but to show me the power of Gods love.
So let us leave the claim that Jesus got himself killed to please himself to those who do believe God to be irrational and thus deny his existence as a God of wisdom and love. Christ, like Socrates, could not be killed by destroying their physical body as they did not let themselves be defined by their physical body. As Christians we should be able to understand that if we understand Jesus to live in our hearts - not just as a physical body.
