Well, we have to respectfully disagree on that. An earthly Messiah, ruling over the earth, is essentially what the Jewish-Zealots believed during the time of Christ. Judas, was influenced by this Jewish Group, as opposed to the Pharisees and Saduccees. When Judas realized that Christ was not interested in throwing out the Roman empire and establishing and earthly temporal Kingdom, this started Judas on the way to betrayal of Christ.

The rejection of the world's fulfillment in a literal messianic kingdom--the reduction to the stark alternatives of a sin-and-misery soaked world and a Heaven of disembodied spirits--has led to the rejection of the latter and the attempted transformation of the former by humanistic schemes (Communism, etc.).
G-d created the world to be fulfilled. Our part is to hasten the kingdom by obeying G-d's commandments. Absent this is only an other-worldly quietism or a militant crusading secularism.
