Acts of Apostles in the Early Church 

When Apollos arrived in Ephesus shortly after Paul's departure, he made an immediate impression on people. He spoke boldly in public, interpreting and applying the Old Testament scriptures effectively.

He debated opponents of Christianity forcefully. And it didn't take long for him to be noticed by Priscilla and Aquila. The couple quickly realized that Apollos didn't have the whole story, however.

His preaching was based on the Old Testament and John the Baptist's message. He was probably urging people to repent and prepare for the coming Messiah. 

Priscilla and Aquila took him home and brought him up to date on all that had happened. As they told him the life of Jesus, his death and resurrection, and the coming of the Holy Spirit, Apollos must have seen Scripture in a new light.

He was filled with new energy and boldness now that he had the complete gospel.

Apollos next decided to travel to Achaia. His friends in Ephesus were able to send along a glowing letter of introduction.

He quickly became the verbal champion of the Christians in Corinth, debating the opponents of the gospel in public.

As often happens, Apollos' abilities eventually created a problem.

Some of the Corinthians began to follow Apollos rather than his message. Paul had to confront the Corinthians about their divisiveness.

They had been forming little groups named after their favorite preacher. Apollos left Corinth and hesitated to return.
