2 Corinthians 8:9

For ye know the grace of our Lord Jesus Christ, that, though he was rich, yet for your sakes he became poor, that ye through his poverty might become rich. [In making liberality the test of love, Paul is reminded of that supreme love of Christ and the test which it endured. The grace of liberality in Jesus caused him to lay aside his glory, and those other attributes of his divinity which were not compatible with his being made flesh, and took upon him our poor and despised humanity, that he might enrich it with all that he had surrendered. The words here should be compared with Philippians 2:5-11. What Christ gave up for us becomes to us a criterion for giving. The love which promoted such a sacrifice should constrain us to sacrifice for others.]
