2 Corinthians 8:11

Now therefore perform the doing of it,.... This is a conclusion from the former advice, to finish what was readily willed; for as it is not enough to do a thing, unless it is done cheerfully and willingly, so it is not sufficient to express a good will to such service as is here called to, without doing it; both should go together:that as there was a readiness to will, so there may be a performance also; in some cases there is neither power nor will to do good; in others there is will, when there is not a power; but in this case of beneficence to the poor saints, as there was a willingness declared, there was an ability in the Corinthians to perform; they had it in the power of their hands, more or less, to act: and the apostle in the last clause of this verse points out the rule and measure of their liberality,out of that which you have; according to your abilities, and as God has prospered you; and with which he shuts up the mouths of all objectors, rich and poor: should the rich say, would you have us give away all we have?
