There comes a time in the life of a believer where they are going to be tested. Anytime we seek to share the Lord with others you can count on there being opposition. Paul and Barnabas experienced just that in their first missionary journey. They ran into a sorcerer who was "perverting the straight ways of the Lord." As a result of being filled with the Holy Spirit the Apostle Paul was able to take out the sorcerer allowing Sergius Paulis top hear the truth of Gods word and becoming a convert.
