2 Corinthians 9:8 - Matthew Poole's English Annotations on the Holy Bible

Having made God, in the verse before, a debtor to those who, by giving to poor distressed saints, would make him their creditor, he here proveth him to be no insolvent debtor, but able to do much more for them, than they in this thing should do at his command out of love to him. He is (saith he) able to make all grace to abound toward you: the word translated grace, signifieth all sorts of gifts, whether of a temporal or spiritual nature; and being here applied to God, (who is the Author of all gifts), it may very properly be interpreted concerning both. God is able to repay you in temporal things what you thus lend him, and so to pay you in specie; and he is able to pay you in value, by spiritual habits and influences. That ye, always having all sufficieney in all things, may abound to every good work; that you may have a sufficieney in all things, so as that you may abound to and in every good work.
