God's Truth Brought To His People
Paul's letters to churches were God's plan for us to read the Apostles' doctrine for ourselves, and let God speak to us today. Although two letters, written by Paul to Corinth, currently exist (1 and 2 Corinthians), each of those mentions another epistle. In 1 Corinthians 5:9-11 he refers to an earlier letter warning against sexual immorality.
