This episode reads Acts 10:44–48 and explores the Holy Spirit falling on Gentiles, their speaking in tongues, and subsequent baptism. Pastor Jackson distinguishes between historia salutis and ordo salutis, and reviews Acts 2 and Pentecost to explain why tongues were foreign languages that signified both judgment on Israel and blessing for the nations.

The sermon argues tongues functioned as a revelatory sign of the unveiled mystery of the gospel—a reversal of Babel and the start of a new age of unity in diversity—and calls listeners to value preaching, means of grace, and pray for the unity of all peoples in Christ.
