What does 2 Corinthians 8:9 mean?
In this section, Paul urges the Corinthians to follow through on a previous commitment to give money to meet the needs of suffering Christians in Jerusalem. He made clear in the previous verse that this is not a command. It is an opportunity to express the love of Christ to other believers.Now he describes how contributing to this gift is Christlike. Jesus was rich and secure in the glory of heaven. He willingly became poor when He became a man, entering into the world of suffering and death in the flow of time on earth. He did this in order to die for the sins of humanity so that all who trust in Him can be forgiven of their sin and one day experience the wealth and security of living in glory with God.
In other words, Jesus demonstrated God's grace by willingly becoming poor so the Corinthian Christians could become rich forever. Now the Corinthians had an opportunity to perform an act of grace themselves that would follow the example of Jesus' own sacrifice.
