Amil sees that the Advent of the Messiah took the covenant nation of Israel and gave it a global, universal mission and dominion over all things. Therefore we are simply the next generation of Joshuas and Davids and Ezras and Pauls and Marys and Deborahs whose mission relates to the victorious destiny and inheritance of the Covenant people of God. We are the people of
Hebrews 11 faith and dominon. We are the People who God has predestined that we might "establish righteousness and subdue kingdoms" as did the heroes of our Faith (Heb 11:33). And so we are the only nation upon earth that has been given all dominion over Heaven and earth to subdue it and establish Christ's law and rule among mankind.
Indeed the Church used to think that way up until the late 1800s and 1900s when the endtimes leaders (Darby, Scofield, Moody, Sunday, Lindsey, Impe, etc) began to teach a doctrine of "predestined endtimes defeatism for the Church." Their prescription to the Church? Withdrawal. Retreat. "Come out from her my people." Don't vote. "You Don't polish brass on a sinking ship." Your kids aren't gonna live long enough to choose a career, spouse or college. Etc. etc. etc.
This short-term thinking has hamstrung our Churches and hamstrung America which was founded on great faith by Christians who were mostly unfamiliar with endtimes short-term thinking patterns. The pioneers of America were builders and people who saw human history through the eyes of all-powerful faith and Divine destiny.
That worldview and faith has been lost due to false endtimes dogmas.
Only return to the Historic Amil view of the unstoppable Victory of the Gospel in the new covenant age will right that ship.
The historic Church has always had an eschatology of victory and hope. Catholic Amillennialists and later the Postmillennial Revivalists (Johnathan Edwards, etc) all have the same belief that the Church will triumph victorious in this age before the final consummation talked about in the historic creeds. As St. John also said, "The darkness is past; the true light now shineth!"
The apostles rightly understood that the purpose for the end of the Old Covenant Era was "that in the ages to come He might show the exceeding riches of His grace in His kindness toward us in Christ Jesus" (Eph. 2:7) and that the Church is God's agent of His own glory and wisdom (Eph 3:1-11, 21). Augustine, Eusebius, the Puritans, and today's Reconstructionists all taught/teach us an eschatology of victory and triumph for the Church (and not doom and gloom).
Amil is the most early and established Christian position on eschatology and it is the position that embraces and affirms the Victory of Christ and His Church in this age.
The Church is the only Nation of Christ that goes on forever, and the Church will never crumble (Matt 16:18-19;Eph 3:9-11,21). However, geo-political nations do come and go, for our God "sets up kings and puts them down" (Dan 2:21)... for God "is the supreme governor among the nations" (Ps 22:28)... for our God "rules over all the kingdoms of the heathen so none is able to withstand Him" (
2 Chronicles 20:6)... and His "is the greatness, and the power, and the glory, and the victory, and the majesty: for all that is in the heaven and in the earth is His; His is the kingdom" (
1 Chronicles 29:11). That is the gospel. That is the rule of law for mankind. That is the reality of the kingdom. The Church was given dominion over all the universe by divine right (Rom 4:12-18; Matt 28:18/Dan 7:14,27; Matt 5:5), and the world belongs to us (1 Cor 3:22) -- but, as with Joshua, the people of God must take it all by faith (1 Jn 5:4).
The vast majority of American evangelicals are dispensationalists, and they have been taught that America is doomed by God's will because we are in the last days. This has been their gospel for at least the past 100 years, and so those evangelicals and their kids and their grandkids were taught
not to govern, run cities, play baseball, launch universities, or even get into media to fulfill one's duty to Christ. Mere personal piety was taught, the kind that doesn't affect anyone or anything else.
Ideas have consequences. As you point out, Dispensationalist ideas have
disastrous consequences (withdrawal, abandonment, escapism, surrender).
Their problem is that dispensationalists were taught a castrated, reduced gospel so that they don't even know what it means to have Christ govern their lives, marriages, jobs, society, and country. Moses understood what it meant to have Christ govern lives, societies, families and country. So did Joshua. And David. And the apostles. And King Jesus. And even many of the fathers of America.
