What is my reward then? — It seems better to omit the note of interrogation, and read the whole verse thus: — What reward then is to be mine, so that (i.e., which induces me) in preaching the gospel I make the gospel without charge (to my hearers), so that I use not my power in the gospel? The “power” being the right to support maintained in 1 Corinthians 9:6; 1 Corinthians 9:12.
