What does 2 Corinthians 9:9 mean?
Within the context of Christians giving freely to meet the needs of others, Paul wrote that God is able to make grace abound (2 Corinthians 9:8). He wants to reassure the Corinthians they can count on God to provide whatever is needed, so they can excel in the good works God has planned for them.As this passage continues, Paul will make the connection between generous giving to others and God's abundant provision. The purpose of this is not to make the giver more prosperous—God is not promising to offer a material "return on investment." Rather, the point is that God will enable the giver to continue in the good works He has prepared for them to do.
Here, Paul quotes from Psalm 112:9 to make the point that God has always been in the business of meeting the needs of the poor. The writer of the psalm declares that God has distributed freely, including his gifts to the poor. One indication of God's eternal righteousness is His generosity. His people should follow His example in giving to those in need, as well.
