One of the most well known aspects of Jesus' ministry was His miraculous healing ability. The gospel accounts are filled with stories of Him healing lepers, the diseased, and more. These miracles are used for a variety of reasons. Interestingly enough, there is at least one instance where a healing is related to the topic of authority.
In the Gospels, Jesus regularly ate with sinners. This is the case even for those who are often rejected in the New Testament, such as tax collectors and prostitutes. This is kind of surprising, isn't it? Absolutely! However, Jesus did not eat with them simply for the sake of physical nourishment. He was teaching them while they ate together.
Paul's boldness was remarkable. He preached the Good News of Christ to Jews and gentiles alike, regardless of their economic or social standing. He taught the poor and rich, men and women, Jew and Gentile. He declared the resurrection of Jesus Christ to kings, and others in authority. All of which was without shame or embarrassment.
