Walking Tall says:
Even if Jesus had been the natural son of Joseph, he couldn't be considered the King of the Jews (in the line of David and Solomon), as some called him, because of the curse placed on Jeconiah by God in Jeremiah 22.
According to this curse, noone from this seed would become king in the future because of Jeconiah's apostasy. However, as an adopted son, Jesus could indeed have overcome the curse, but only if Judah were still a kingdom and not currently under Roman oppression.
Jesus never claimed that his kingdom was of this earth, but some others may have wondered, due to the royal genealogy of Joseph and in doubting that his son's birth was of divine origins. Perhaps Jesus, in being seen as the expected Messiah, would cause them to believe that he would suddenly declare himself to be the rightful king and bring the wrath of Rome on the Jewish people for a final confrontation.
That's what you get for thinking! More likely, as the adopted son of Joseph, he chose to abdicate his sonship rights to become the suffering servant of other prophecies in the Old Testament record, and, as a result, became the Savior of the world who is worshipped today by many millions rather than a few first century A.D. zealots. By losing himself, Jesus of Nazareth gained for us our salvation, which is the true meaning of his name Jeshua (God is our salvation).
Praise God for the humble mind and character of the person of Christ!
