II Corinthians 8:10-14

And in this I give advice: It is to your advantage not only to be doing what you began and were desiring to do a year ago; but now you also must complete the doing of it; that as there was a readiness to desire it, so there also may be a completion out of what you have. For if there is first a willing mind, it is accepted according to what one has, and not according to what he does not have. For I do not mean that others should be eased and you burdened; but by an equality, that now at this time your abundance may supply their lack, that their abundance also may supply your lack—that there may be equality.
