1 Corinthians 9:11
If we have sown unto you spiritual things, [is it] a great thing if we shall reap your carnal things?
Note 7 at 1Co 9:11: The spiritual things that are given to us through godly ministers are infinitely more valuable than money. It is the very least we can do to share our carnal resources with them in exchange. "Be not deceived; God is not mocked" (Ga 6:7). Ministers who have sown true spiritual seed will reap financial blessing.
