My example is actually not good so that's fair to point out. How about this? One cannot preach to not cheat on their spouse and yet, still cheat on their spouse. And further more, claim to be faithful and then claim to follow the ten commandments. It's a lie.
I don't expect anyone to be perfect. We make exceptions for certain cases that are trivial. This case is not trivial. Kim Davis is affirming her position of power and her actions due to her religion and specifically a "higher" authority. She says its a situation concerning "heaven and hell" for her. Those are her quotes, not mine. Yet, she still defy's this "higher" authority concerning the accepted idea of Christian marriage. I'm not making these rules up, you Christians are. This is hypocrisy. Plain and simple. This questions her moral ground and weakens her overall religious character.
The bottom line... If you preach something, you have to live up to it, yourself, and not only demand from others. It really is that simple. Otherwise, don't preach it. Isn't this fair to assert?
