Paul uses this question to emphasize that "the service that the ministry of the Spirit" must be more glorious than "the ministry of death" [verse 7](./07.md) because it leads to life. Alternate translation: "So the service that the Spirit does must be even more glorious." (See: [[rc://en/ta/man/jit/figs-rquestion]])
This refers to the new covenant, of which Paul is a minister. Alternate translation: "the ministry that gives life because it is based on the Spirit" (See: [[rc://en/ta/man/jit/figs-explicit]])
