Is The United States A Christian Nation?

"The Majority of people in the United States are Christian"
In a recent national poll, as many as 90% of the people in the United States consider themselves Christian in some way. A Christian viewpoint certainly dominates the U.S. culture. In broad outlines, most people in the U.S. believe in one God who created the universe and that Jesus died for our sins. Almost everyone has good things to say about Jesus in the U.S., even those who do not claim to be Christians. People desire to be forgiven for their sins and they think that Jesus is ready to help them.
However, most people in the U.S. do not understand what Jesus demands to follow him, let alone follow it. To be a "Christian" may be a good thing, but it is mostly a social title today, having nothing to do with Jesus’ death or teaching. Even the majority of people who go to churches have a false understanding about what it means to be a follower of Jesus. Most people will agree that Jesus said, "I am the way, the truth and the life: no one comes to the Father except through me" (John 14:6). But they do not agree with or even understand the following:
If anyone is to enter the kingdom of God, they must obey the teaching of Jesus. (Matthew 7:21-27)

If anyone is to follow Jesus, they must deny themselves and take up their cross. (Mark 8:35)
If anyone wants to gain their life, they must lose it. (Mark 8:36)
Whoever wants Jesus to accept them before the Father, they must accept Jesus before men. (Mark 8:38)
No one can follow Jesus unless they renounce their possessions. (Luke 14:33)
Those who will gain the kingdom of God must be poor, mourning and persecuted. (Luke 6:20-24)
Whoever will be raised from the dead must humble themselves. (Luke 14:11)

These are the demands of faith, and the people of the United States, especially the "Christians", are usually looking for ways to avoid this faith of Jesus, not embrace it.

"The Laws of the United States are based on the Bible"
Some say that the foundation of the law of the United States is based on a British system of law, which is based on the Bible, especially the Ten Commandments. The Declaration of Independence and the Constitution are based on "Christian" principles. Thus many people think that the laws of the U.S. are fundamentally Christian.
However, the laws of the United States have been drawn up and applied without reference to the teachings of Jesus, which is the basis of the laws of the kingdom of God. Seven of the Ten Commandments are not enforced by the laws of the United States. The makers of the laws of the U.S. are not concerned with the Bible, but with making the society well-running on their own principles, not on the principles of God.
Here are a few examples of where the law of God and of the United States are in opposition:

The law of God insists that idolatry is unacceptable. (Exodus 20:4; II Corinthians 6:16-17)
The law of the United States says that everyone has a right to worship whoever they want.
The law of God insists that those who take God’s name in vain will be punished. (Exodus 20:7; Matthew 12:31)
The law of the United States insists on freedom of speech, without punishment.
The law of God forbids covetousness and greed. (Exodus 20:17; Ephesians 5:3)
The law of the United States encourages corporations that thrive on greed.
The law of God says to teach one’s children about loving God. (Deuteronomy 6:7; Ephesians 6:4)
The law of the United States forbids the public teaching about God.
The law of God teaches to love everyone, even if they harmed you. (Matthew 5:43-44)
The law of the United States insist that the police and the military must harm others, and even encourage them to kill, if the threat seems bad enough.

The laws of the United States are, in many ways, opposed to Scripture, not in agreement with it.
"The United States is a Christian Nation"
The early colonists of the United States were all Christians, many persecuted for their faith. North America has been the site of many major revivals, which caused many towns to turn completely to the Lord. The majority of the leaders of the United States have been Christian, and have written statements that could be called devotional. So many say that the United States is a Christian nation, or that it should be.
However, the United States cannot today be called a Christian nation—nor can any nation on the earth. There is already a Christian nation, called the kingdom of God and Jesus is the king. There can be no other nation with any other system of government with anyone else as leader that could call itself "of Jesus" or "Christian". The kingdom of God already has its people all throughout the world. And though the kingdom does not now have a land that it can call its own, it is very much a living, vibrant nation.
On top of this, the United States is opposed to the kingdom of God in many areas. Following are many areas that the United States and the kingdom of God are diametrically opposed:

The kingdom of God is a distinctly religious kingdom, devoted exclusively to God.
The United States separates any religious practice or belief from the government.
The kingdom of God is a nation in which every member and citizen is devoted exclusively to God through Jesus Christ. (Romans 10:9)
The United States insists that every citizen can worship whatever God they want, or none at all, and hold to any teacher they want. To insist otherwise, it claims, is unethical.
The kingdom of God is a country ruled by an appointed benevolent dictator: Jesus Christ (Romans 1:4)
The United States firmly believes that only a republic where the leader is voted in by the people is a proper government.
The kingdom of God has all of its laws and ethics come from God himself, and all policies are allowed to be determined by local bodies, as long as they do not judge apart from God’s law. (James 2:8-10)
The United States judges according to the laws passed by their legislative body, with no regard to God’s will.
The kingdom of God is empowered by the Holy Spirit. (Romans 14:17)
The United States is empowered by economic and military strength—namely, the flesh.
The kingdom of God has values such as faith, love, endurance through persecution, following the teaching of Jesus that are requirements to remain in it. (Acts 14:22)
The United States does not promote love, generosity to the poor, devotion to God, faith in Jesus, humility, sound teaching or other values that would cause one to enter the kingdom of heaven.
The kingdom of God insists that one’s security comes from God alone, who sends angels to fight for it. (Matthew 26:52-53)
The United States firmly insists on having the strongest, most superior armed force in the world to promote its own security and its ideals.
The kingdom of God insists that greed must not be found among God’s people. (Ephesians 5:3)
The United States promotes greed, self-gratification and spending beyond one’s need as the backbone of its economy.
The kingdom of God teaches that to hate or destroy one’s enemy is to be unlike God and unworthy to be in God’s kingdom. The kingdom of God claims that God’s way is to do good to one’s enemy and pray for that one. (Luke 6:27-36)
The United States promotes the destruction of their enemies, killing even innocents in the pursuit of their goals of revenge, security and economic stability.
The kingdom of God grants salvation to those who have faith, obedience and love in Jesus Christ. (Galatians 5:5-6)
The United States grants its salvation to those who qualify and have filled out the proper paperwork—whether rich or needy, deserving or swindlers.

The United States, like all other nations, is not any kind of a Christian nation. It is a secular state, based on the principles of the world. It is completely opposed to God’s ways of running his nation.
