text: "my god, my god, why have you forsaken me?"? did jesus lose his faith here?   or did he just do that to fulfil scripture. if so, what's the significance of saying it? well you are partly right. he became seperated for god for a short time so he  could take the sins of all of us upon him. god can not look upon sin so jesus was alone and human on the cross. he paid the ultimate price.he never lost his faith because he and god are one person. there is a passage that when he was praying in the garden of gesemane he said oh that you would take this cup from me(his crucifiction) but he then prayed but it is your will not mine that be done.so i dont know if this helps you any but it shows the fulfilment of the prophsey and that he had to be human to die for our sins yet never lost his faith or beliefs.
