Acts 2 · a question people ask
Joel's words in Peter's mouth say, "The sun will be turned into darkness, and the moon into blood" (2:20). Did that happen on the day of Pentecost?
The chapter doesn't say. Peter says, "But this is what has been spoken through the prophet Joel" (2:16), and gives Joel's words all the way to "whoever will call on the name of the Lord will be saved" (2:21): the Spirit poured out (2:17-18), wonders and signs (2:19), and the sun and the moon "before the great and glorious day of the Lord comes" (2:20). Of what his hearers saw, he says, "he has poured out this which you now see and hear" (2:33). The chapter tells of no darkened sun that day, and Peter says no more of the sun and the moon than Joel's words. These notes don't say more either.
The verses
“Being therefore exalted by the right hand of God, and having received from the Father the promise of the Holy Spirit, he has poured out this which you now see and hear.”
