Spiritual and material benefits (1 Cor. 9:11)

“If we have sown

Spiritual goods

Among you,

Is it too much

If we reap

Some of your material benefits?”

Εἰ ἡμεῖς ὑμῖν τὰ πνευματικὰ ἐσπείραμεν, μέγα εἰ ἡμεῖς ὑμῶν τὰ σαρκικὰ θερίσομεν;

Paul once again asked if we have sown (ἐσπείραμεν) spiritual goods (τὰ πνευματικὰ) among them (Εἰ ἡμεῖς ὑμῖν), was it too much or a great thing (μέγα) if we reaped material benefits from them (εἰ ἡμεῖς ὑμῶν τὰ σαρκικὰ θερίσομεν)? Only the Pauline letters used this word πνευματικὰ, that means spiritual, and the word σαρκικὰ, that means pertaining to the flesh, carnal, or earthly.  Paul then asked the obvious question with the obvious answer.  If they had sown spiritual things among them, was it too much to ask for some earthly or material benefits.  His obvious simple answer was yes.  They might expect some material benefits for their spiritual benefits.  Do you think that people should get material benefits for spiritual benefits given?
