Today we will continue with the topic begun in Chapter 8 last month, that is, the Church collection. It is to be noted that Chapter 9 cannot be separated from Chapter 8. Imagine them as one continuous text as Paul flows back and forth between exhortation, doctrine, and logistics (as he does throughout this whole letter).
Chapter 8 ends with the matter of Titus being sent ahead of Paul. Chapter 9 beings with the same train of thought.
