This verse is central to Paul's teaching on Christian giving (8:1–9:15). The Corinthians were known for their spiritual gifts (1 Corinthians 1:5–7; 14:12). Now, they should lead in the generous act of giving, which shows true spirituality (see 1 Corinthians 13:1–13). God had been generous to the Corinthians, so they should help the Jewish believers in need (2 Corinthians 9:13). This would show unity in Christ.
