A shipwreck landed Paul and others on an island called Melita (Acts 28:1). The Bible says that those people of that land were barbarians. When a viper latched onto Paul’s arm, these barbarians assumed that this was judgment because of some crime he had committed (Acts 28:3-4). When Paul simply shook off the viper into the fire and remained unharmed, the people claimed that Paul must have been a god (Acts 28:6). Although these people were superstitious and ignorant concerning the truth, it appears that they had an understanding of hospitality. Because of the rain and cold, the native people kindled a fire and received Paul and those with him. In addition to this, a man named Publius received Paul and lodged him three days. The world should never consistently display more hospitality than Christians.
The Bible seems to point to Pharaoh most often as an example of someone with a heart hardened through sin and the deceitfulness of power and fame. Pharaoh's hardened heart led him from one rebellious act to the next. He constantly fought against the Lord and the Lord’s man. Even after all of the miracles in Egypt and the abundance of judgments, he chose to pursue the children of Israel as they departed from Egypt. Pharaoh's hardened heart led him to pursue them to the Red Sea. Out of all the troublesome effects of a hard heart, the most troubling aspect is that it refuses to hearken to the words of the Lord. On at least five occasions, the Lord makes this connection (Exodus 7:13, 22; Exodus 8:15, 19; Exodus 9:12). A hard heart closes the ears to the truth and sets the individual up for greater judgment.
