2 How while they were undergoing every sort of trouble, and were in the greatest need, they took all the greater joy in being able to give freely to the needs of others. 3 For I give them witness, that as they were able, and even more than they were able, they gave from the impulse of their hearts, 4 Seriously requesting us that they might have a part in this grace of being servants to the needs of the saints: 5 And going even farther than our hope, they first gave themselves to the Lord and to us after the purpose of God.
Matthew Henry's Commentary on 2 Corinthians 8:2-5
Commentary on 2 Corinthians 8:1-6
(Read 2 Corinthians 8:1-6)
The grace of God must be owned as the root and fountain of all the good in us, or done by us, at any time. It is great grace and favour from God, if we are made useful to others, and forward to any good work. He commends the charity of the Macedonians. So far from needing that Paul should urge them, they prayed him to receive the gift. Whatever we use or lay out for God, it is only giving him what is his own. All we give for charitable uses, will not be accepted of God, nor turn to our advantage, unless we first give ourselves to the Lord. By ascribing all really good works to the grace of God, we not only give the glory to him whose due it is, but also show men where their strength is. Abundant spiritual joy enlarges men's hearts in the work and labour of love. How different this from the conduct of those who will not join in any good work, unless urged into it!
