27 Apollos had been thinking about going to Achaia, and the brothers and sisters in Ephesus encouraged him to go. They wrote to the believers in Achaia, asking them to welcome him. When he arrived there, he proved to be of great benefit to those who, by God’s grace, had believed. 28 He refuted the Jews with powerful arguments in public debate. Using the Scriptures, he explained to them that Jesus was the Messiah.
Apollos knew his Bible and believed in Jesus.
Because of this, he was a great benefit to others who believed.
