Read Matthew 22:15-22.
"Give to Caesar what is Caesar's and to God what is God's."
The Christian's relationship to government is very simple. We are to humbly submit, just as Christ submitted. In a democracy, we have a say in what government does, but when the vote goes against us, we are still submit. Give to Caesar what is Caesar's.
Whereas we may not like it, paying taxes is not an issue for the Christian because we know that life is more than money. The part of us, the most important of us, that is to be given to God, does not consist merely of money.
So the Christian submits humbly to the government, but knows that their loyalty to government is a minimal part of their life. Their true loyalty is to God. Give to God what is God's. And therefore, if the government asks us to do something contrary to God's commands, then it is our duty to object and disobey the government in favor of obeying God.
Give to the government what is the government's (taxes, humble obedience in all matters not contrary to God's will, and to God what is God's (your very self, your first loyalty).
