In the capacity of an official representative of the Body of Christ, I would like to make the following statement:
The "Pray for Obama: Psalm 109:8" bumper stickers that certain cars are sporting do not, in any way, reflect the attitude for which Christians are to be known in the world. Putting it simpler: You cannot justify the use of these stickers from a Christian viewpoint. Putting it simpler: These stickers are horrible and should not be used by any who call themselves followers of Christ.
Or, put it this way: If you truly are a follower of Jesus of Nazareth, and if you attempt to live your life according to God's Word, then DON'T GET ONE OF THESE STICKERS!
Also, if you're none of the above, then I apologize for this blatant misuse of scripture to make a foul political point. This is deceptive, it is not 'cute' as it purports to be. This is just plain wrong. And it's nothing to joke about.
Christians are told to pray for those in authority over us. But this is what our attitude is supposed to look like:
I urge, then, first of all, that requests, prayers, intercession and thanksgiving be made for everyone— for kings and all those in authority, that we may live peaceful and quiet lives in all godliness and holiness. This is good, and pleases God our Savior, who wants all men to be saved and to come to a knowledge of the truth. - 1 Timothy 2
Everyone must submit himself to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God. Consequently, he who rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves. - Romans 13
Remind the people to be subject to rulers and authorities, to be obedient, to be ready to do whatever is good, to slander no one, to be peaceable and considerate, and to show true humility toward all men. - Titus 3
Submit yourselves for the Lord’s sake to every authority instituted among men: whether to the king, as the supreme authority, or to governors, who are sent by him to punish those who do wrong and to commend those who do right. For it is God’s will that by doing good you should silence the ignorant talk of foolish men. Live as free men, but do not use your freedom as a cover-up for evil; live as servants of God. Show proper respect to everyone: Love the brotherhood of believers, fear God, honor the king. - 1 Peter 2.
Seriously. . .is it all that difficult? You don't have to like the guy; you don't even have to agree with, nor support, his policies. But this is what we are called to do: Submit to him, pray for him (pray that he comes to a knowledge of the truth), be thankful for him, be obedient and humble toward him, refrain from slandering him, honor him. All those things are right there in the Book. Right there in the New Testament.You may not feel like doing any of those things, but you don't really have a choice. You either do those things, or you stand disobedient before God.
When we go around behaving silly and stupidly, misusing the Text to make some sort of political joke, we sin against God, we disobey the Biblical mandate before us, we make a mockery of the Bible in front of the world, we make fools of ourselves, we damage our credibility, we sacrifice our witness and mission on the altar of political tomfoolery.
Is this clear enough for you? Come on, Christians. Let's be smarter than this. Let's do what the text actually calls us to do. Let's be above the mud-slinging and cynicism. Let's pray for the man. Better that he come to follow the wisdom of God, than something terrible happen to him and cause more chaos in the land. Better we be models of peace and humility than we lose any shred of respectability we have left.
