The bible doesn't say that. In fact,Christs rule on earth is nearing it's end. Christs rules from the new kingdom in the third heaven after his second coming.
The proof that this prophecy has been fulfilled can be seen in two momentous events: the unprecedented global warfare that has characterized the Twentieth Century, and the quiet transition from Christian to secular rule across the planet that has accompanied all this warfare.
The millennium of world Christian rule, then, has come and gone and almost no one on earth realizes that such an event has even occurred. Instead of premillennium's and postmillennium's, God has given us a contemporary millennium, and it has come wrapped in the peal of church bells.
The millenium of the Messiah encompasses the duration of Christ's treaty of peace with Babylon(biblical name for the world). It describes the time alloted for salvation on earth before the gate is closed and Jesus returns. We can see that it has lasted almost 2000 years. That means God has doubled the millenium, giving us, in His benevolence, twice what the prophecies stipulated.
That He would do this was foreseen by Joshua.
The duration of Christ's offer on earth is described as the "Day of Atonement". As long as it lasts it represents the light of Christ beaming on earth. It is a "Day of the Lord" a day described in scripture as being 1000 years as far as man is concerned (Ps.90:4). The word "millenium", then, means "Day" of God.
Joshua prophesied that Christ's "Day" would be extended by God. Under the influence of the Holy Spirit, he said that the sun did not set for almost two days (Joshua 10:13-14). That is precisely where we are now. It has been almost 2000 years since Christ walked and preached on earth.
And, true to the prophecy, we can see a "Great Revolt" sweeping God's offer of reconciliation away. The 'Son' is setting; darkness is returning. God's offer is about to be withdrawn. The gate is closing, bringing the 'millenium' of Jesus on earth to an end. That, of course, is what "Persia" is all about, the blistering east winds of prophecy that have now begun to blow in from the Euphrates.
