According to Peter, a good citizen is one who obeys the law of the state and fulfills his obligations. This means that a good citizen should respect the laws and authority of the state, pay taxes, and do their civic duties. Peter emphasizes that Christians should be model citizens and not engage in any behavior that would bring shame to the Christian faith. However, providing for the poor and offering social services are also important aspects of being a good citizen, but Peter specifically emphasizes obedience to the law and fulfilling obligations as the primary characteristics.
