Did the Davidic royal line continue despite the ungodly kings of Judah?
Yes. God promised David that through him would come a royal family, the house of David. Even though ungodly kings came down through history, the royal blood kept together until the birth of Christ, coming especially through Mary, while Joseph was included as the legal father in that Davidic genealogy.
Les points to 2 Samuel chapter 7, where God gives David the promise that through him would come this royal family—the house of David. He explains that even though there were ungodly kings coming down through history, the royal blood kept together until the birth of Christ. That line came especially through Mary, who was the physical mother; God is the Father, and Joseph was the legal father, so Joseph also had to be included in the Davidic genealogy.
