2 Corinthians 9:8

8.And God is able Again he provides against the base thought, which our infidelity constantly suggests to us. “What! will you not rather have a regard to your own interest? Do you not consider, that when this is taken away, there will be so much the less left for yourself?” With the view of driving away this, Paul arms us with a choice promise — that whatever we give away will turn out to our advantage. I have said already, that we are by nature excessively niggardly — because we are prone to distrust, which tempts every one to retain with eager grasp what belongs to him. For correcting this fault, we must lay hold of this promise — that those that do good to the poor do no less provide for their own interests than if they were watering their lands. For by alms-givings, like so many canals, they make the blessing of God flow forth towards themselves, so as to be enriched by it. What Paul means is this: “Such liberality will deprive you of nothing, but God will make it return to you in much greater abundance.” For he speaks of the power of God, not as the Poets do, but after the manner of Scripture, which ascribes to him a power put forth in action, the present efficacy of which we ourselves feel — not any inactive power that we merely imagine.

That having all sufficiency in all things He mentions a twofold advantage arising from that grace, which he had promised to the Corinthians — that they should have what is enough for themselves, and would have something over and above for doing good. By the term sufficiency he points out the measure which the Lord knows to be useful for us, for it is not always profitable for us, to be filled to satiety. The Lord therefore, ministers to us according to the measure of our advantage, sometimes more, sometimes less, but in such a way that we are satisfied — which is much more, than if one had the whole world to luxuriate upon. In this sufficiency we must abound, for the purpose of doing good to others, for the reason why God does us good is — not that every one may keep to himself what he has received, but that there may be a mutual participation among us, according as necessity may require.
