The introduction of Acts ends with a surprising scene. In the wake of Christ’s ascension, intriguing attention is given to the apostles returning to Jerusalem, praying as they wait for the outpouring of the Holy Spirit, and seeking to replace Judas Iscariot—the apostate apostle. This peculiar passage appears obscure to many. How does it connect with Christ’s ascension? How does it relate to the outpouring of the Holy Spirit? What significance does it have in the book of Acts? Why does it take up so much space and form the conclusion to its introduction? This sermon seeks to unfold these and related observations in this important passage to show that the ascended Christ is reigning from above.
