 And then after you have those, there's only one history book that tells about the early church, the spread of the gospel. That's the book of Acts. And then we have Paul's letters to the churches, which is nine of those. Romans, 1 and 2 Corinthians, Galatians, Ephesians, Philippians, Colossians, 1 and 2 Thessalonians. And then you have the next four, which are Paul's letters to individuals, 1 and 2 Timothy, Titus, and Philemon. And then there's nine letters.
