Acts 1

Verse-by-verse explanation

1. Acts 1:1The “former treatise” Luke mentions is the Gospel of Luke, written earlier for the same recipient, Theophilus—probably a man of social standing who financed or sponsored the work. Acts begins as a direct continuation of that story.
2. Acts 1:2This verse bridges Luke’s two books: the Gospel ends with Jesus’ ascension, and Acts picks up at the same point, noting that before He was taken up, He had already chosen the apostles who would carry the mission forward.
3. Acts 1:3The “forty days” of appearances after the resurrection appear only here, in Acts; the Gospels give no exact number. It was the period during which Jesus kept meeting with the disciples before He was taken up into heaven.
4. Acts 1:4The “promise of the Father” is the Holy Spirit, already promised by Jesus before He died. That is why He tells the disciples not to leave Jerusalem: they needed to wait for that gift to arrive, which happens ten days later, at Pentecost.
5. Acts 1:5John the Baptist immersed people in water as a sign of repentance; now Jesus promises something different—the Holy Spirit Himself coming upon the disciples, fulfilled ten days later at Pentecost.
6. Acts 1:6The question shows that the disciples still expected a political Messiah, one who would drive out the Romans and restore Israel to an independent kingdom like in David’s time. Jesus neither confirms nor denies this—He simply redirects the conversation.
7. Acts 1:7Jesus refuses to give a date for the end of the age, saying that kind of calculation belongs to God alone. It is an answer that shifts attention away from the disciples’ political question toward the mission He explains next.
8. Acts 1:8This verse works almost like a summary of the entire book: preaching first in Jerusalem, then in Judea and Samaria, and finally in the farthest places—it is basically the geographic outline that Acts follows chapter by chapter.
9. Acts 1:9The ascension scene describes Jesus being lifted up while the disciples watch, until a cloud hides Him from their sight. In the Bible, a cloud usually marks the presence of God—it is not just a detail about the weather.
10. Acts 1:10Two men dressed in white suddenly appear beside the disciples; white clothing usually indicates that they are angels, even though the text does not use that word directly.
11. Acts 1:11The angels ask why the disciples keep looking up at the sky, since there was nothing left to see, and promise that Jesus will return the same way He went up: visibly, in the clouds.
12. Acts 1:12The phrase “a sabbath day’s journey” was a Jewish measure, about half a mile, the maximum distance the law allowed someone to walk on the Sabbath without it counting as work. It is simply a way of saying that the Mount of Olives was very close to Jerusalem.
13. Acts 1:13The “upper room” was the top floor of a house, used as a meeting room. The list gives the eleven apostles who remained after the death of Judas Iscariot, without repeating his name.
14. Acts 1:14Besides the apostles, the group gathered in prayer included women, Mary the mother of Jesus, and Jesus’ own brothers, who according to the Gospels did not believe in Him before the resurrection.
15. Acts 1:15Peter takes the lead of the assembled group, about a hundred and twenty people in all—a number that gives a sense of the size of the Christian community right after the ascension, before the great growth of Pentecost.
16. Acts 1:16Peter understands that Judas’ betrayal did not catch God by surprise: he reads the episode as the fulfillment of an ancient prophecy, attributed to King David, written in the Psalms.
17. Acts 1:17Peter recalls that Judas was not an infiltrator or a stranger, but one of the Twelve, counted among the group and with his own role within Jesus’ ministry, which makes the betrayal even more serious in the listeners’ eyes.
18. Acts 1:18Judas bought a field with the money from his betrayal and died there in a violent way. The account in Matthew 27 tells the story a bit differently, saying that it was the priests who bought the field and that Judas hanged himself; scholars debate how to reconcile the two versions, but they agree on the final outcome.
19. Acts 1:19The field Judas bought became known among the residents of Jerusalem by the Aramaic name Aceldama, meaning “The field of blood,” a direct reference to the violent way he died there.
20. Acts 1:20The word “bishoprick” here is an old translation for an office or position of responsibility, with no connection to a church bishop today. It is about Judas’ place among the Twelve needing to be filled by someone else.
21. Acts 1:21Peter sets the criterion for choosing Judas’ replacement: it had to be someone who had closely followed the whole of Jesus’ public ministry, not a recent convert.
22. Acts 1:22The required period runs from John’s baptism to the ascension—in other words, the person chosen had to have seen Jesus alive before the cross and personally witnessed His resurrection afterward.
23. Acts 1:23Joseph, called Barsabas, and Matthias were the two candidates presented to replace Judas. The requirement was to have followed Jesus from John’s baptism to the ascension, so they came from the wider group of disciples, not strangers chosen from outside.
24. Acts 1:24Before deciding between the two candidates, the group prays, asking that God, who knows the heart of every person, show which of the two He had already chosen; the final decision was seen as God’s, not an ordinary vote.
25. Acts 1:25“His own place” is an indirect way of referring to Judas’ tragic fate after the betrayal, without repeating the details of his death already told in verse 18.
26. Acts 1:26Casting lots was a common method in ancient Judaism for discovering God’s will, similar to drawing marked stones. This is the last time the Bible mentions this method being used—after Pentecost, decisions come to be made in a different way.
