I go back and forth quite a bit in my thoughts on the relationship between God, government, Christians, politics, etc. I read this yesterday in a journal article and found it helpful:
“Jesus lived in a conquered province in an empire whose imperialistic ruler stood for everything that was antagonistic to the revealed faith of the Jews. Jesus was not a revolutionary but instead conformed to the laws of civil government. Nowhere did he denounce the legitimate power of the state. Jesus paid his taxes (Matthew 17.24-27). He recognized the authority of Pontius Pilate, even when Pilate unjustly delivered him over to his enemies (John 19.11). Jesus reminded him, however, that his authority was not autonomous (John 19.10-11) but that it was delegated from the One who was above. Thus, in practice and precept Jesus recognized that the government under which he lived was ordained of God.”
