Lord’s Day worship sits at the very center of the church’s life, and careful exegesis of John 20:21-23 grounds that claim rather than assuming it. The Spirit’s work of judging sin, promised in John 16:8 and enacted in 20:23, gives the church real authority beyond any ceremonial function. In a real sense, this closing sermon argues, the whole church in its totality is already present in John 20.
The Transfiguration, just before this in Luke, recalls the Exodus and anticipates the glory to come, and it reframes Martha’s ordinary hospitality in chapter 10. Her house becomes a temple, and her distraction shows the wrong kind of service. Busyness for Christ and right service of Christ are two different things.
Pastoring is hard, and 2:24-3:9 ties that difficulty to the troubles Paul names as marks of ‘the last days.’ Other passages on the last days fill out the picture. Churches absorbed in their own serenity, expecting ease in place of the soldier’s life Paul describes, labor under a real fallacy.
