The Christmas Song (French- i'll assume) is NOEL, and it states "Born is the KING of Israel" A Jewish man himself, was Jesus. He would be one of of the "Chosen Children of GOD" - already.
His SON's or daughter's would be ALL Jewish people, and seems GOD would say thay are all his children. All would be considered KING's & Queen's- princes, prince, etc.
GOD would be KING, because of his blood line. But we have NO DNA to prove it for anyone.
Christains are BORN of Sin already. This to say, they must WORK for a FREE pass to the after-life or HEAVAN or king James Definition: "The SKY's above". -(NOT a place too where one can go sit down to eat, drink, or play a harp at)
If Jesus was Christain - that is a FREE pass to hell, and Jewish people do NOT belive in HELL. Why would he, as a Jewish man wish to save the Human soul by creating a NEW cult?
