Chapter 9

First five verses continue about the gift the Corinthians will give to the Jerusalem church.  Paul has bragged of their generosity and will be  humiliated if they don't come through in spectacular fashion.  He's even sending some men ahead to make sure it's all tied up with a bow before those from Macedonia get there.

Paul says the point is this:

6 The point is this: whoever sows sparingly will also reap sparingly, and whoever sows bountifully will also reap bountifully. [2Co 9:6 ESV]

But it is also that we are to give as we decide, and not reluctantly.  Implication seems to be that our giving reflects our heart.

MSB says giving goes by an agrarian principle.  If you want a huge harvest, sow a huge amount of seed.  Whatever you sow, in like proportion, you receive in blessings.
