If you compare the genealogies of Matthew 1 (Joseph’s) and Luke 3 (Mary’s) you would understand that both Joseph and Mary were “of the house and lineage of David”. Mary was the descendant of David’s son Nathan, brother of Solomon. Joseph was from the line of Solomon.
The lineage of Christ that enables Him to sit on the throne comes through Mary, not Joseph.
One of Joseph’s ancestors, Jehoiachin, was cursed that no descendent of his would ever sit on the throne. (Jeremiah 22:30)
Luke 3:21-4:13

A pleasure as always:)
