Many believers assume geopolitical considerations concerning the faith as if it's the social gospel (actually a misnomer) or political reform were the Second Great Commission. "Seek the prosperity of the city..." (cf. Jer. 29:7). This a social mandate, not a social gospel. We are its salt and light, not its savior. America is a secular nation and not a Christian one, no matter how many believers make this land their home. Always keep the main thing the main thing and save souls as Job One.
We are not to stoop to the level of radical or fundamentalist Islam and institute Christian Shari'ah law, which forces everyone to live like a Christian, whether they are Christian or not. God doesn't expect heathens to live like believers. We are held to a higher standard! Our nation established freedom from religion, as well as freedom of the exercise of religion, and no sect has the right to impose its views on the others--note that secular humanism and atheism are considered religions. We may have started out with our forefathers as a predominately Christian nation, but today it is highly multicultural and diverse ethnically and religiously. We are the salt as preservatives of morality and to give meaning and enjoyment to life, and also as light to show the way and how people should live in spiritual darkness--not political darkness, but moral depravity and in need of salvation, as the Bible sanctions no specific or certain type of government or economy.
What is legal is not always moral or right and could be sin or evil, and what is illegal may be the moral thing to do in an act of civil disobedience to unjust laws. The state may recognize gay marriage, for example, but that doesn't mean God recognizes it--it doesn't become right or moral by an act of governmental decree. We cannot legislate morality, law is merely the majority vote that licks all others, according to Justice Oliver Wendell Holmes, though Christians differ because they believe that God is the only Legislator and all law must comply with Him. Christians should never cease to drive basic morality in society as salt and light, but be aware that there are gray and doubtful or questionable areas where people should be free to make their own personal choices. Government is a "social contract" according to John Locke and Jean-Jacques Rousseau, whether we want to be in it or not, or knowingly or not, according to contract laws. The Bible sees government ordained by God to restrain evil in the world.
Jesus alone will usher in His kingdom and His kingdom is not of this world--we are not to get too comfortable in this life and become too much at home, for our conversation and real citizenship is in heaven! Remember, at your homecoming you are not home yet! Oliver Cromwell failed in making England a Christian nation. The Puritans also attempted to make a Christian nation and John Calvin even tried his hand at it while mayor of Geneva--both utter failures and examples that the Great Commission is to spread the gospel and change lives, not to change the government--the Bible is a beacon of light unto salvation, not a social tool for government reform.
Governor William Bradford of Plymouth Colony wanted to "advance the kingdom of Christ" when he settled here, but he misunderstood the Great Commission and the doctrine of eschatology. It is a well-known fact that the Salem witch hunts showed the failure of instituting the Christian faith and making the Bible itself the law of the land. Jesus will bring about His kingdom in due time when the body is full and complete with all His lost sheep saved.
Jesus told Pontius Pilate that His kingdom is not of this world. Pilate then perceived Him to be a philosopher or harmless dreamer, but no threat to Caesar. If His kingdom were of this world His followers would fight, but we have no such marching orders. Many misled, though sincere believers throughout history have tried to usher in the kingdom of God, and thought that the church's job was to aid in doing it. As William Bradford, Pilgrim governor in Colonial America, said that his mission was to "advance the kingdom of Christ." The Puritans also tried legislating Christianity in early America, but it failed and turned out to have evil fruit, such as hanging innocent women accused of witchcraft. John Calvin even tried to enforce biblical mandates on Geneva, like mandatory Sabbath observance and even forbidding anyone from naming children anything but biblical names.
Only Christ will usher in the kingdom of God and our marching orders are to fulfill the Great Commission, not to reclaim a nation for Christ. Yes, we are light and salt, but we must not lose focus and keep the main thing the main thing. Christians are not to dedicate their lives to the betterment of society unless God calls them specifically to this. The "social gospel is not only a misnomer but has no place in the church. We are interested in saving souls and winning people, not becoming political activists. The Bible is meant to be a light for salvation, not government reform or social activism. Everyone has the obligation to be involved in his society that behooves a responsible citizen.
Entering the kingdom is synonymous with getting saved. The whole purpose of announcing the kingdom of God to be at hand is to make people realize the urgency to repent and get ready for the second coming of Christ in glory. The first words out of John the Baptist and Jesus in their ministries was to repent. The kingdom is both present in the here and now, and future to be fulfilled at the Second Advent. Presently Christ reigns in the hearts of His followers and we shall all reign with Him in His millennial kingdom after the tribulation period. Jesus said that if He cast out demons by the finger of God, "the kingdom of God has come upon you." Salvation (the fulfillment of our redemption) is nearer now than when we first believed according to Romans 13:11.
We are to do kingdom living while sojourning on this earth as pilgrims, this is not our home and we should realize that our true citizenship is in heaven (cf. Philippians 3:20). We are just passing through and have spiritual green cards and this life is but a staging area or tryout for eternity, where each note we play has eternal vibes. We are rehearsing for kingdom living and our faith must be tested and God wants to prove our faithfulness and reward it according to our deeds done through faith by the power of the Holy Spirit (cf. Isa. 26:12; Hos. 14:8). Like Paul said (cf. Rom. 15:18), he would not venture to boast of anything, but of what Christ has accomplished through him.
We are not to seek nor store up treasure in this life nor to seek earthly fame, fortune, nor power, but to seek spiritual riches and to learn to live in the power of the Holy Spirit in God's kingdom. God's kingdom is invisible and only God knows who is in it for sure or who the elect are (cf. Mark 13:27 "... and shall gather his elect from the four winds..."). Jesus said to "seek ye first the kingdom of heaven" and this means that our number one priority is kingdom living in God's economy, and when we put God first in our lives all else falls into place. As it says, "all these things shall be added unto you."
The richest people are not those with worldly wealth, but those most content in what God has blessed them with and faithful stewards of our resources, time, talents, gifts, money, and opportunities. Someone has said that riches are not in the abundance of our possessions but in the fewness of our wants. When we seek first God's kingdom all our priorities become focused on Christ and our life is oriented in the right direction and given divine purpose and meaning. In sum, we ought to live one day at a time in light of eternity--not regretting the past, nor worrying about the future.
Though Pilgrims made a compact to usher in the kingdom of God. or literally to "advance the kingdom of God," it failed. Little doctrine did they know but that Christ will usher in His kingdom, and that His kingdom is not of this world. America is supposedly the "Great Experiment." They would've done a better job of it and speeded His coming (cf. 2 Pet. 3:12); we ought to always be about "hastening the day of His coming." The question is how this is accomplished. It doesn't mean passing legislation or beginning new governments such as a great experiment. Or like the Social Experiment that failed called Prohibition. Jesus gave us the Great Commission to spread the good news and make disciples, some seek the Second Great Commission to reform society to their agenda and to be a social gospel to help the needy and down and out, we must be lights and not just turn stones into bread but spread the good news.
Jesus kingdom would reign in human hearts, not on the throne of an earthly king or monarch. All authority has been given Him. Jesus is the King of kings and Lord of lords and we are to make this real in our lives, not force it on others. We don't conquer territory in the name of Christ, but hearts with love. We love them into the kingdom. "Love conquers a multitude of sins," God promised Abraham that his descendants would be a blessing and God saves us to be a blessing (cf. Zech. 8:13) and we are heirs of Abraham as believers.
We never stop expanding Christ's kingdom and when He comes the church age will cease and Satan will have a pass or permission to bring in his idea of a kingdom dominated by him and the antichrist. There have been many antichrists so to speak that had the notion to conquer the world: Alexander the Great, Julius Caesar, Napoleon, Hitler, et alia. The ancient Egyptian, Assyrian, Babylonian, and Persian empires all aspired to world domination, but the Spirit restrains the evil one. The spirit of antichrist is already here.
We are never to despair that God is not in control ("Blessed is the nation whose God is the LORD"). His Providence is governing all events and creatures small and great. Yes, God doesn't just reign, He rules ("For the kingdom is the LORD's, and he is the governor among the nations") not like a do-nothing king or the monarch of the UK who has no powers though they reign. But we are to receive Christ as Lord of our hearts and let Christ's kingdom grow from there by the preaching of the gospel message and living it out as witnesses. We must admit we are not in charge, nor is any earthly ruler in charge, without any reservations in our lordship decisions--submission is an issue for some.
("The king's heart is in the hands of the LORD..."). What does this mean but we owe complete allegiance and obedience to Christ. We pledge allegiance to the Lamb on the throne! No governor or ruler can do anything outside God's will or permission (cf. Lam. 3:37). We must be encouraged that the only king who is capable of ruling hearts is Jesus. He has been called the Emperor of love. Christ is indeed the only Potentate and Ruler of heaven, the entire universe, not just earth--all things visible and invisible.
We must not just render lip service to God but bow in obedience to His sovereignty. Every knee shall bow to Him! This obedience is to the command to repent and stop the charade or hypocrisy and also to put our complete faith and submission in Christ as Lord and trust as Him as Savior. Christ demands the throne room of our hearts, the pass key to our complete soul, and if He isn't there, we are there and in control of our lives, it cannot be neutral! We must give Christ the ownership of our lives.
We must remember that Satan claims the soul of the infidel and actually influences him to evil and sin, and the only way to get free from his tyranny and power is to surrender to Jesus: We must say "No!" to Satan before saying "Yes" to Jesus. It is obvious that Satan is having his heyday and we must seek to be set free. "If the Son shall set you free, you shall be free indeed." But after the church age, Satan will have his day to do as he wills: to take over the world for a period of tribulation on earth. After we belong to Christ, we are no longer in Satan's kingdom, the kingdom of darkness, and belong to God in His kingdom and are protected from the evil one who cannot touch us. Soli Deo Gloria!
