Right. But it would have felt instant for him if we assume he wasn't aware of anything while he was dead.Jesus wasn’t instantly resurrected. He was dead and in the grave / tomb for three days and three nights.
If you believe Jesus is God, then yes, he did say that he wanted to die for mankind's sins.Did God ever say that he wanted to die?
Yes. He had a human body.Returning to Jesus, do you think he was ever a human person?
