Political secularism, if by secularism one means that there is an absence of God(s) that is/are driving the actions of governmental business is an impossibility. No man or magistrate engages reality apart from a commitment to some God, gods, or god concept. Everything the political powers do is done with the tip of the cap (whether consciously or unconsciously) to some god(s) of some copybook heading.
Because this is so, the Biblical Christian advocates and champions the crown rights of King Jesus to rule explicitly over the political affairs of men. Of course, even if wicked magistrates are ruling, they are ruling by God’s divine decree but that fact doesn’t change the reality that wicked magistrates must be called on to rule according to the precepts of Jesus Christ found in His Word.
The doctrine of common grace, if it is held, does not change any of this. One can believe that in common grace God can do relative good through wicked magistrates and still believe that wicked magistrates are required to Kiss the Son lest God be angry and the wicked magistrate perishes in the way.
Secularism, as it is currently embraced, which is a form of pluralism, which in turn is an expression of polytheism, is not a political arrangement that any Biblical Christian can be comfortable with without being disobedient to the crown rights of King Jesus.
There is an implication here that people are not going to like. If we, as Christians are not to embrace secularism as what pleases the God of the Bible then we are not allowed to vote for candidates who will continue the secular arrangement wherein God is not pleased. We can hardly, consistently, oppose secularism and keep pulling levers for people who will continue on with secularism.
