What does 2 Corinthians 9:12 mean?
Paul is urging the Corinthians to give generously to meet the needs of suffering Jewish Christians in Jerusalem. Because of the persecution they are enduring, they are in great need. This verse indicates that supplying the needs of these people is only one reason for giving as a "ministry of service." The other thing that is being accomplished is that this service is overflowing in many thanksgivings to God.A believer's choice to give generously provokes gratitude to God, from those who receive the gift. Paul's emphasis on this tells us at least two things. First, receiving thankfulness from His people matters deeply to God. He cares about that. Christian giving is one way to bring to God something that He desires.
Second, giving is about far more than just fixing a problem of not enough money. When Christians give in a Christlike act of grace, the spiritual results matter as much or more than meeting physical needs for food, shelter, and safety.
