As documented by the Gospel of Matthew and the Gospel of Luke, Jesus is a 28th generation descendant of King David of Israel and simoultaneously a 42nd generation descendant of Abraham, the founder of the Jewish nation, the father of Isaac. Jesus, who was born in Bethlehem, is indeed the true Jewish King.
Luke has also documented that Jesus is a descendant of Adam, the first human. He is not a descendant of Cain, though, but rather of a third son of Adam named Seth.
God fulfilled His promise. He sent His Son to the Earth. His Son is the real Jewish King. And that’s the best news anyone could hear on Christmas.
