Let's look at Jesus. Jesus was born of the time of the Roman Empire and he was born a Jew. The Roman government was very harsh towards the Jews at the time, and the Jews wanted a new ruler, someone that can take down the current Roman government. (And this has been the story of the Jews for a while even to this day. They left Egypt, then they have a nation in Canaan, they have some kings, they get captured by the Assyrians, then exiled by the Babylonians, then returned to Israel, and then a few hundred years later, Romans were over this part of land until the time of Jesus, and beyond.) Jesus was born into a hostile environment, so much that he and his family had to escape to Egypt to hide for a while before they came back. (On a side note, this will lead to the topic on immigration.) In his later life, he went around Israel, teaching folks about God and His salvation. In his short time, he encouraged the minds and hearts of those who followed him until his death and resurrection. Most importantly, he is salvation for those who believe in him (John 3:16-17, Ephesians 2:8). For most of his life and ministry, we don't really know much about what Jesus thought about the Roman government. But what we do know is how he interacted with the people around him and the hope that he has given them.
In the Bible, the first part of Romans 13 does have this passage regarding government:
1 Let everyone be subject to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God. 2 Consequently, whoever rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves. 3 For rulers hold no terror for those who do right, but for those who do wrong. Do you want to be free from fear of the one in authority? Then do what is right and you will be commended. 4 For the one in authority is God’s servant for your good. But if you do wrong, be afraid, for rulers do not bear the sword for no reason. They are God’s servants, agents of wrath to bring punishment on the wrongdoer. 5 Therefore, it is necessary to submit to the authorities, not only because of possible punishment but also as a matter of conscience.The Apostle Paul wrote this during this time of the Romans, after Jesus's resurrection. Paul knew of the persecution that the early Christian had to go through with the Romans and endured this persecution himself. So, it's kind of a hard passage to take in, and I would image, even for Paul, since he was the one who got jailed by the Romans. And what we're experiencing here in the U.S. pales in comparison of what Paul had to go through.
6 This is also why you pay taxes, for the authorities are God’s servants, who give their full time to governing. 7 Give to everyone what you owe them: If you owe taxes, pay taxes; if revenue, then revenue; if respect, then respect; if honor, then honor.
What does that really mean, even if we do not agree with the government we are under, or for those who are Christians in other nations who may be under a different form of government?
First, we definitely need to pray for our authorities, the good, the bad, and the ugly. Even in this passage in 1 Timothy 2:1-6, prayer for our authorities is "good, and pleases God our Savior, who wants all people to be saved and to come to a knowledge of the truth." Going back to Romans 13, I believe this is really saying to stay out of trouble and obey the laws that make sense and are in line with God's law of grace and love.
Second, respect for the government and all those around us. God has allowed and gave us government for a lot of reason (order, rules, military protection, etc). We may not understand everything God is doing through government, and we may not agree with everything the government is doing, but God does want us to respect it. (1 Peter 2:11-17).
Thirdly, prayer for our nation. I know we do not always agree with everyone around us. But I believe if those who proclaim to be Christians, we must unite to pray for our nation. (2 Chronicles 7:14)
Jesus never wanted a physical earthly kingdom of his own but he knows God is building a heavenly kingdom for those who follow him. In due time, the United States may not be here anymore, no matter what you believe in prophecy. Sometimes I feel people hold too much hope on government, when government is merely a thing of human invention. Same with the Constitution. Although, I have all respect for the founding fathers of the United States and the Constitution they have written, it is not the ultimate law. Rather we should hold God's grace much higher than these laws (Galatians).
