According to Bible Jesus supposed to the descendant of David, and also according to Bible Jesus also is the "Son of God".
2 Samuel 7:8 "So now, say this to my servant David: This is what the Lord of hosts says: . . . . 7:12 When the time comes for you to die, I will raise up <b>your descendant,</b> one of your own sons, to succeed you, and I will establish his kingdom.
Luke 1:27 to a virgin engaged to a man whose name was Joseph, a descendant of David, and the virgins name was Mary.
Jesus can NOT be BOTH "Son Of God" and also the descendant of David.
Joseph, Jesus father, had nothing to do with Jesus genealogy!He didn't do it!
