“For you know the grace of our Lord Jesus Christ, that though he was rich, yet for your sake he became poor, so that you by his poverty might become rich” (v9). Paul encouraged the Corinthians to take part in a generous offering for poor churches. He pointed to the example of the Macedonian churches, who experienced severe affliction: “their abundance of joy and their extreme poverty have overflowed in a wealth of generosity” (v2). The other example was Jesus himself, who became poor so that we would benefit.
“They gave themselves first to the Lord …” (v5). Genuine love for the Lord and appreciation for His sacrifice naturally overflow into generosity toward others
