People who tend to lean more Republican/Conservative more often than not put more focus on the more dogmatic aspects of Christianity. The dogmatic aspects of Christianity are important because they preserve the structure. People who tend to lean more Liberal/Democratic more often than not put more focus on the more spiritual side of Christianity. The spiritual aspects of Christianity are important because they update the structure. Both are important and play their role.
One aspect of the Republican platform, which by the way I’m not advocating, that does I feel speak to Christian values is the concept of personal responsibility. In the end you will need to give an account to God and nobody will be able to vouch for you on your behalf. Ultimate responsibility for your Christ-like walk and faith lies with you. What you will find by studying the political platforms is that both sides have aspects that are biblical and other aspects where they are not. That’s why there really is no correct answer as to which political side a Christian ought to advocate for and why politics can divide the church.
