When Apollos decided to go on to Achaia province, his Ephesian friends gave their blessing and wrote a letter of recommendation for him, urging the disciples there to welcome him with open arms. The welcome paid off: Apollos turned out to be a great help to those who had become believers through God’s immense generosity. He was particularly effective in public debate with the Jews as he brought out proof after convincing proof from the Scriptures that Jesus was in fact God’s Messiah.
