I respectfully disagree. A very Godly woman from one of our Congregations that I knew for over 50 years recently passed. She was a Business Owner, and served on the City Council here for years. She also worked with her Congregation, as well as serving on the State Board for our Congregations here in the State.
She gave much time, and donated I don' know how much money to various Congregations around the State that were on hard times, or struggling to stay open. She was a true Christian, a Godly woman, and her and her husband (who is an Ordained Minister, and Licensed Counselor) were/are long, long time friends of our family.
She is but one example. I know many more locally, State wide, and Nationally. I do agree that far more Politicians claim to be a Christian than there really are, but that in no way means a Christian can not be called by God to serve in a Political position.
