Tulipman said: "You should know that theonomists believe that the Christianizing of nations will come through the preaching of the gospel, and not the institution of Mosaic law. Theonomy teaches that the preaching of the gospel and the conversion of souls will effect the change, a change that ought to (or in the case of Postmillenialist Theonomists, will) include the desire the abide by the law for civil society, as well as for the other arenas of life."

Reformed Christians believe that the elect become Christians by the proclamation of the Gospel. They also believe that obedience to God and His laws are a bi-product of a truly regenerate person.
If I understand what you are saying, this is not quite the same as what you are saying concerning Theonomists.
I guess my problem with reconciling A-millennialism with Theonomy is if I understand you correctly when you mentioned "Christianizing of nations" it sounds more like an optimist view such as Post Millennialism than it does with a more pessimistic view like Amillenialism.
I don’t remember reading any material written from an A-millennial position that talked about the Christianizing of nations.

Perhaps I am misunderstanding what you are saying? All I know is I am having a hard time wrapping my mind around this subject, despite the fact that I have been reading a lot of material pro and con on the matter.
