2 Corinthians 7-9

It took me about 15 minutes to read this passage. In the first chapter Paul talks about the benefit of discipline, though he doesn't use those words. When Christians work in conjunction with the Holy Spirit the pain of discipline produces life. If we work outside of the Spirit all our efforts will only produce death.
Then Paul spends the next two chapters talking about the bounty that is ours in Christ as we give our monetary gifts to the work of God's kingdom. To reenforce his words Paul quotes from Exodus 16:18 and Psalms 112:9.
