The story of Jesus is fiction, so first understand there is no Jesus and no baptism by John because John the Baptist is also a fictional character. But in the story Jesus is baptized it for the fulfillment of all righteousness which makes no sense at all. If Jesus is God then he would be perfectly righteous and not needing to fulfill anything.
SO HOW IS IT YUKON JACK CAN BREAK DOWN THE GOSPELS AND EXPOSE THE FRAUD?
BECAUSE BIBLE SCHOLARS AND APOLOGISTS, ALMOST TO THE MAN, ARE DISHONEST LIARS PROTECTING THEIR BELIEFS
The author of the Jesus story is Josephus, a Rabbinic scholar, who was captured by Rome during the Judean War in 68 AD, then taken back to Rome in 70 AD and paid to write the Gospels. A Jewish scholar wrote the myth, using commonly held beliefs of the day to convince the readers that Jesus was divine and could beat death, and thus you could beat death if you believed in him.
The story is all make believe as no one can walk on water or raise dead people, and no one can rise from the dead. That is fiction. It is a lie. It is a big fat Jew lie told by a Jewish scholar Josephus to cast a spell on your mind that death can be beat when it can not. We all die, but since we are self aware, we do not want to die, so we believe a salvation story in denial of reality.
So the real reason why John baptized Jesus was to get you to believe the story line. That is the correct answer to the puzzle as to why the Jew Zeus God got baptized. And it is all bullshit, because no human is perfect nor can be, and a story of the perfect man is fiction. Furthermore, you do not have to get baptized to get right with God, but you should bathe and clean yourself.
