Acts 19:6
And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied.
Primary
What this passage establishes
When the Holy Ghost comes on the Ephesian disciples, they speak with tongues and prophesy.
Why it matters in the argument
Acts gives observable accounts of people receiving the promised Spirit. Those narratives supply the Bible’s clearest pattern for recognizing Spirit reception.
Apostolic connection
Apostolic teaching distinguishes the initial sign of tongues when the Spirit is received from the later congregational gift that requires interpretation.
Common misunderstanding
Paul’s question ‘do all speak with tongues?’ concerns distributed gifts in the assembled body, not the repeated initial sign in Acts.
How to use it in conversation
Start with the promise, then compare Acts 2, 10, and 19. Use 1 Corinthians only after distinguishing initial sign, private prayer, and public gift.
