Bible Study: The Rejected Apostle Part 4

2 Corinthians is the 4th letter Paul wrote to the church in Corinth. It is a teaching on the church that rejected his apostleship. In it Paul shows the cosmopolitan church that she might be saved but she has not gone through transformation yet.
2 Corinthians 7:1
Therefore, since we have these promises, dear friends, let us purify ourselves from everything that contaminates body and spirit, perfecting holiness out of reverence for God.
