I was asking ... how did Jesus raise himself from the dead?
He didn’t. The reason being, Jesus is nothing more than a plagiarized mythological character extracted from numerous religions, all of which predate Christianity by several centuries, including (but not limited to) such personas as Dionysus, Osiris and Attis.
Unsurprisingly, the cross of the zodiac (a symbol plagiarized many centuries later by Christianity) is one of the oldest conceptual images in human history. It reflects the sun as it figuratively passes through the twelve major constellations over the course of a year. It also reflects the twelve months of the year, the four seasons, and the solstices and equinoxes. The term zodiac relates to the fact that constellations were anthropomorphized, or personified as figures or animals. In other words, the early civilizations did not just follow the sun and stars, they personified them with elaborate myths involving movements and relationships – myths which far predate Christianity by hundreds of thousands of years.
The sun, with its life giving and saving qualities, was personified as a representative of the unseen creator or god (later tuned into the Christian god). God’s sun, the light of the world, the savior of human kind. All of these ideas were supplanted from far more ancient religions and into Christianity. This is precisely why there is absolutely zero factual evidence for the existence of a Jesus Christ outside the Bible. Historically speaking, it is infinitely more easy to prove the existence of, say, Julius Caesar (or many other identities from similar eras) than Jesus Christ. This is because he was neither a charlatan nor an amateur poseur such as “David Koresh”; rather, he never existed at all - he was a copied persona from a multitude of pagan belief systems and compounded into one ideal. From virgin birth to the three Wise Men to a death followed by the resurrection, and even the dates of the holidays Easter and Christmas, all were ideas thought up long before the character Jesus Christ was plagiarized into existence.
