Acts 18:27-28

[27] And  when he  was disposed  to pass  into  Achaia,  the brethren  wrote,  exhorting  the disciples  to receive  him:  who,  when he was come,  helped them  much  which had believed  through  grace:  [28] For  he mightily  convinced  the Jews,  and that publickly,  shewing  by  the scriptures  that Jesus  Christ. 

What does Acts 18:27-28 Mean?

Contextual Meaning

Armed with his new understanding Apollos proceeded west where he ministered at Corinth by watering the gospel seed that Paul had planted ( 1 Corinthians 3:6). The Christians in Ephesus encouraged him by providing letters of commendation that introduced him to the Corinthian church (cf. 2 Corinthians 3:1). This is the first mention of a church in Ephesus. Perhaps Paul planted it ( Acts 18:19-21), but someone else may have done so since he appears to have been there only briefly on his way to Jerusalem. Maybe Priscilla and Aquila planted it.
Apollos was so effective at instructing the Corinthian believers and refuting Jewish objectors that he developed a strong personal following in Corinth ( 1 Corinthians 1:12; 1 Corinthians 3:4). He does not seem to have been responsible for encouraging the party spirit that his presence there generated ( 1 Corinthians 4:6; 1 Corinthians 16:12). He proved from the Old Testament that Jesus was the Messiah (cf. Acts 8:35; Acts 18:5; 1 John 5:9).
The word order in the Greek text favors the view that "through grace" modifies "believed" rather than "helped." The Corinthian Christians had believed the gospel through the grace of God ( Acts 18:27; cf. Ephesians 2:8-9).
