Take a look over my shoulder
First of all, I don't make the rules. God is the one who has a zero tolerance for sin from a legal standpoint. When Jesus was murdered by Jew & Gentile - having never sinned, but only did what was good and right, he provided an alternative to personal death & judgement for the believer. From God's point of view, that death was good enough to be a substitute for the death legally required for each sinner, if received.
As for getting the gospels and the resurrection back to the time of the actual event, I found the video below to be quite convincing.
