Reformed and evangelical Christians believe that the Bible is the only infallible rule of faith and practice. But in our pluralistic society not everyone is reformed or evangelical. So, many (probably most) do not hold to this belief. Moral codes and laws depend on broad acceptance and support.
Should Christians vote for and work for laws which reflect biblical views? If they believe that all mankind is answerable to one God who has revealed His law in Scripture, then the answer is “yes.” Bible believers will be told they are trying to impose their views on others, to make their standards normative for all. But if the Bible is true, it is God who has imposed His standards on us all and we ignore them to our own peril. As laws are made in our congress or state houses, someone’s view is imposed, a biblical view or a secular one. I think a biblical view is better than a secular one, even for those who otherwise have little or no regard for the Bible. If you disagree, don’t worry. I have only one vote. If it fails, I will suffer the consequences that come. Change my belief, I cannot.
Though they know God’s righteous decree that those who practice such things deserve to die, they not only do them but give approval to those who practice them. Romans 1:32
