How can Christians have radar detectors? “Let every person be subject to the governing authorities. For there is no authority except by God’s appointment, and the authorities that exist have been instituted by God. So the person who resists such authority resists the ordinance of God, and those who resist will incur judgment (for rulers cause no fear for good conduct but for bad). Do you desire not to fear authority? Do good and you will receive its commendation, for it is God’s servant for your good.” (Romans 13:1-4) Ditch the detector. Honor God. Obey the law.
