Rom 13:1-5 . . 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.
. . . For rulers hold no terror for those who do right, but for those who do wrong. Do you want to be free from fear of the one in authority? Then do what is right and he will commend you. For he is God's servant to do you good. But if you do wrong, be afraid, for he does not bear the sword for nothing. He is God's servant, an agent of wrath to bring punishment on the wrongdoer. Therefore, it is necessary to submit to the authorities, not only because of possible punishment but also because of conscience.
There are Christians who honestly believe that capital punishment is wrong, but according to the passage above, and the one below, capital punishment is divine.
"And for your lifeblood I will surely demand an accounting. I will demand an accounting from every animal. And from each man, too, I will demand an accounting for the life of his fellow man. Whoever sheds the blood of man, by man shall his blood be shed; for in the image of God has God made man." (Gen 9:4-6)
Rom 13:1-5 is a fair warning to Christians that should they break the law; to expect neither favoritism nor immunity. So then, if you can't do the time, then don't do the crime.
Christians that commit capital crimes should expect their heads to roll just like any other capital criminal's head; and that goes for lesser crimes too, e.g. J-walking, illegal U-turns, feeding parking meters, drifting through stop signs without coming to a complete halt, exceeding the speed limit, unsafe lane changes, road rage, disturbing the peace, littering, trespassing, shoplifting, civil disobedience, animal abuse, etc.
God has given government the right to play God; any Christian who opposes government's right to play God, is playing the Devil. God forbid! Christians really ought to be the most law-abiding people on Earth; but unfortunately, many are shamefully guilty of conduct unbecoming.
"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." (1Pet 2:13-15)
