You are talking about the same earthly messianic kingdom which has caused the majority of the Jewish nation to stumble and fall.
The Messianic Kingdom, Jesus Christ's kingdom, is not an earthly kingdom. Think about it, if Jesus' kingdom is eternal, and it is, then it cannot be earthly because this old earth is not eternal, this earth and everything in it is temporal, the opposite of eternal, and will one day pass away and there will be a new heavens and a new earth. So if this present earth will one day pass away, how do you figure a kingdom of this earth can last forever? The only thing that is eternal, that will last forever, that will never pass away, is Heaven, the Kingdom of God and of His Christ, the Kingdom where even now Jesus sits on the throne reigning over all things, a throne by the way that sits in the heart of the New Jerusalem, and from which the river of the water of life flows from which we and the nations of the redeemed have drawn the water of everlasting life.
Jesus' kingdom, the Messiah's kingdom, is God's Kingdom, the kingdom of heaven, the ONLY kingdom that Jesus ever taught! That's why you have this sense that in Jesus' kingdom there will be no sinners living in rebellion against him. That's why you have this sense that in Jesus' kingdom there will be no fear, there will be no war, no fighting, no wickedness, no evil. You know this much, but you're had it all scrambled up by these prophecy guru's to believe that Jesus' kingdom will be a physical, earthly kingdom that has not yet come.
But the Kingdom over which Jesus reigns has come brother, and you have been born into and become a citizen of it, along with countless multitudes from every nation on earth, and a remnant of Jews among whom are numbered Abraham and Moses, David and Daniel, Paul and John, Peter and Nicodemus. You are in very good company brother, the company of the saints, citizens of the Eternal Kingdom of Heaven.
In Christ,
Pilgrimer
