If Jesus Christ was who He claimed to be, and He did die on a cross at a point of time in history, then, for all history past and all history future it is relevant because that is the very focal point for forgiveness and redemption.

Jesus claimed He had the power to raise himself from the dead and His followers would be raised from the dead. That's a unique claim in the literature of religion.

If they had connived a scheme, and Christ had not been raised from the dead, where would have been the hardest place on the face of the earth to convince anyone? In Jerusalem.
