"The word must in verse 1 is gigantic in its implications. There are no contingency plans in heaven. No mere probabilities; no plan B; no bail-out clauses. Everything is assured. This is neither fate nor karma. This is King Jesus who not only holds the ‘stars’ and walks among the ‘lampstands,’ but also before whom one day every knee is going to bow and every tongue is going to confess that He is Lord, to the glory of God. In the remaining twenty-one chapters of Revelation all of these titles and images of Jesus, and more, are brought to life."
