The Apostle Paul is a good example of using every opportunity to share his faith story and influencing anyone he met for Christ. He even shared his faith with an angry mob in Jerusalem. Paul shared before the Jewish Council, then with governors Felix, then Festus, and before King Agrippa, who was almost persuaded to believe the Gospel. At every turn, even when shipwrecked on Malta, Paul told everyone the Gospel and how God changed his life.
