From my early days as a Christian it made sense to me that the Bible has something to say to all of life. The Bible is certainly not a spiritual cookbook. It is not always straightforward how one should arrive at one’s decision. The book of Proverbs, and the whole wisdom tradition, showcase this sort of nimble discernment. Christians disagree over the proper interpretation and/or implications of the Bible. And those are Christians who agree on the binding authority of the Scriptures!
I continue to believe that is problematic to have Christians who rationalize or diminish the president’s rhetoric. That said, I Tim. 2:1,2 is a significant influence on how (at the present) I will vote. My vote is very much influenced by the person and party I believe that best protects religious liberty.
