We continue our #VosGroup series in pages 173–174 of Vos' book Biblical Theology: Old and New Testaments to consider uncleanness and purification, a deep structure of Scripture, what Vos says, "forms a fundamental conception, which . . . has entered into the permanent fabric of biblical religion."

This week on Theology Simply Profound, Rob and Bob discuss preaching in the context of Paul's ministry of the word when Eutychus fell asleep at the window, fell to ground dead, and was raised up to life again (Acts 20:7-12). Why is it that Paul would speak so long to these people? What is preaching? What is its purpose? We discuss these questions as well as many related and unrelated things, too!
