1 We want you to know, brothers, about the grace of God that has been given among the churches of Macedonia, 2 for in a severe test of affliction, their abundance of joy and their extreme poverty have overflowed in a wealth of generosity on their part. 3 For they gave according to their means, as I can testify, and beyond their means, of their own accord, 4 begging us earnestly for the favor of taking part in the relief of the saints— 5 and this, not as we expected, but they gave themselves first to the Lord and then by the will of God to us. 6 Accordingly, we urged Titus that as he had started, so he should complete among you this act of grace. 7 But as you excel in everything—in faith, in speech, in knowledge, in all earnestness, and in our love for you—see that you excel in this act of grace also. 8 I say this not as a command, but to prove by the earnestness of others that your love also is genuine.

2 Corinthians 8:1-8

7 Each one must give as he has decided in his heart, not reluctantly or under compulsion, for God loves a cheerful giver.

2 Corinthians 9:7
