God would match the Corinthians' generosity (9:10–11). Their generosity would help Jewish Christians (9:12), honor God (9:13), and show believers in Jerusalem that their non-Jewish brothers and sisters were true believers (9:13). This would lead to Jewish believers praying for and caring about the non-Jewish believers (9:14). Paul imagined a united, worldwide Christian church made up of both Jewish and non-Jewish believers, all united in Christ Jesus (Galatians 3:28; Ephesians 2:11–22). This unity would strongly show the Lord's work of bringing people together.
