Jimmy Carter is a man who, by all accounts, has an extremely deep Christian faith. I don't remember him ever donning the trappings of a religious leader and using Jesus as some sort of campaign slogan. He didn't have to.
We have some jokers out there right now who are trying to woo the evangelicals by simply lying through their teeth. And evangelicals are buying it. I'm talking about Romney, for one. It seems to me that the churches need to do a better job of teaching their flocks what is really in the Bible as opposed to the talking points they're getting from whatever source.
1 Peter 2:13-21 is often used out of context to justify all sorts of behavior including slavery. No where in that part of scripture is there any sort of justification for treating anyone with anything but love and kindness. What it tells us is that people who choose to be Christians need to accept the authority of their governments, even if it is pagan or somehow anti-Christian. We are to be good citizens as far as we can be without sinning against God and if that means being punished for our beliefs then we are to accept that punishment cheerfully. The key is that this is a voluntary submission to authority for the good of the Church and the glory of God. If we choose to speak out against the government then we should not be the least bit surprised when punishment comes our way. This is far more difficult to swallow than just crowing that we are citizens of a "Christian Nation" and somehow deserve all sorts of special treatment.
13 Submit yourselves for the Lord’s sake to every human authority: whether to the emperor, as the supreme authority, 14 or to governors, who are sent by him to punish those who do wrong and to commend those who do right. 15 For it is God’s will that by doing good you should silence the ignorant talk of foolish people. 16 Live as free people, but do not use your freedom as a cover-up for evil; live as God’s slaves. 17 Show proper respect to everyone, love the family of believers, fear God, honor the emperor.
18 Slaves, in reverent fear of God submit yourselves to your masters, not only to those who are good and considerate, but also to those who are harsh. 19 For it is commendable if someone bears up under the pain of unjust suffering because they are conscious of God. 20 But how is it to your credit if you receive a beating for doing wrong and endure it? But if you suffer for doing good and you endure it, this is commendable before God. 21 To this you were called, because Christ suffered for you, leaving you an example, that you should follow in his steps.
