A.T. Robertson Commentary 1 Corinthians 9:11

"If we sowed unto you spiritual things, is it a great matter if we shall reap your carnal things?" — 1 Corinthians 9:11 (ASV)

Is it a great matter? (μεγα; ). The copula εστιν has to be supplied. Note two conditions of first class with ε, both assumed to be true. On πνευματικα and σαρκικα see on 2:14; 3:3. This point comes out sharply also in Ga 6:6.
