2 Corinthians 8:10-12

10And 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;

11but 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.

12For if there is first a willing mind, it is accepted according to what one has, and not according to what he does not have.
