As Paul deeply explains the purpose and need for salvation, he shows the freedom in Christ and how that freedom is displayed in our own lives.
Paul addresses and corrects those who oppose the ministry God has given him to the Corinthians. He also writes to Rome to make the case for God's righteousness through the cross.
Paul writes another letter to the church of Corinth, saying that while they have allowed false teachers in, Paul is encouraged by their repentance. Then, Paul shows how his suffering can lead to the comfort of others.
