Shall we obey God or men?

When rulers defy God, they lose their God-ordained authority. When rulers require lesser authorities to cooperate in and facilitate evil, the lesser authorities must resist. As John Knox stated, “True it is, God has commanded kings to be obeyed; but likewise true it is, that in things which they commit against His glory, He has commanded no obedience, but rather, He has approved, yea, and greatly rewarded, such as have opposed themselves to their ungodly commandments and blind rage.” Calvin was even more blunt:  “For earthly princes lay aside their power when they rise up against God, and are unworthy to be reckoned among the number of mankind. We ought, rather, to spit upon their heads than to obey them.”
