Verse-by-Verse Commentary
The Book of Acts
Chapter 1: Wait for the Promise
Before the church could be born, it had to wait. The risen Jesus tells His followers not to rush out and work, but to wait in Jerusalem for the promise of the Father: they will be baptized with the Holy Spirit and receive power to be His witnesses to the ends of the earth. Then, as they watch, He ascends, and two angels promise His return. Acts 1 is the hinge between the gospel of Jesus and the age of the Spirit, and it turns on one command: wait for the promise.
About This Commentary
This is a verse-by-verse study of Acts chapter 1. For each section you will find the KJV text, the Greek words that sharpen the meaning, plain explanation, and a Gospel Focus. Acts records the birth and spread of the church in the power of the Holy Spirit, and it opens with the promise that made it all possible. Every Scripture quotation is from the King James Version.
Setting the Stage
The Acts of the Spirit
Acts records how the gospel spread from Jerusalem to Rome in the power of the Holy Spirit. It is the history of the early church and the pattern for how people were added to it.
Luke the Physician
Luke wrote Acts as the second volume of his work, continuing the story from his Gospel. Again addressed to Theophilus, it carries on "all that Jesus began both to do and teach."
Between Ascension and Pentecost
The risen Jesus spends forty days with His disciples, then ascends. Chapter 1 covers His final instructions, the ascension, and the waiting days before the Spirit is poured out.
Power from on High
The church's mission is impossible without the Holy Spirit. Before they could witness, the disciples had to wait for and receive the promised power from on high.
Baptized with the Holy Spirit (Acts 1:4-5)
Jesus commands His followers to wait for something only God can give.
Wait for the Promise of the Father
"The former treatise have I made, O Theophilus, of all that Jesus began both to do and teach, Until the day in which he was taken up, after that he through the Holy Ghost had given commandments unto the apostles whom he had chosen: To whom also he shewed himself alive after his passion by many infallible proofs, being seen of them forty days, and speaking of the things pertaining to the kingdom of God: And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me. For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence. When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel? And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power."
Greek Study
Jesus commands the disciples to wait for "the promise of the Father," for "ye shall be baptized with the Holy Ghost not many days hence." The verb baptizo means to immerse, to overwhelm -- the same word used of water baptism now applied to the Spirit. John baptized in water; Christ will immerse His people in the Holy Ghost. This is not a vague blessing but a definite, coming experience, promised by the Father and about to be poured out at Pentecost -- the birthright of the whole church.
Explanation
The risen Jesus spends forty days speaking of "the things pertaining to the kingdom of God," then commands the disciples not to act but to wait -- everything depends on the coming of the Spirit. When they ask about restoring the kingdom to Israel, He redirects them from speculation about times to the mission before them. The Spirit they are to receive is not an optional enrichment but the indispensable power for witness. The book of Acts will be the story of what this promised baptism produces: an ordinary group of disciples turned into world-shaking witnesses.
Gospel Focus
Jesus calls the gift of the Spirit "the Promise of the Father", something God had long pledged (Joel 2:28; Ezekiel 36:27) and now would give. And notice the command: "wait." The disciples had walked with Jesus for three years, yet He would not send them out to build His church on their own strength. They needed to be "baptized with the Holy Spirit." This baptism, promised here, would fall at Pentecost and become the pattern the apostles preached: "ye shall receive the gift of the Holy Ghost" (Acts 2:38-39). No amount of zeal or training can substitute for the Spirit. The first lesson of the church is to wait for and receive the power God promised.
You Shall Receive Power (Acts 1:8)
Jesus redirects the disciples' curiosity about the future to their mission in the present, and promises the power to carry it out.
Witnesses to the End of the Earth
"But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight. And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel;"
Greek Study
"Power," dunamis (δύναμις). Mighty, effective power, the root behind our word "dynamite." The Holy Spirit does not merely comfort; He empowers for mission.
"Witnesses," martys (μάρτυς). The word from which we get "martyr." A witness testifies to what he has seen and knows, and many of these witnesses would seal their testimony with their lives.
Explanation
Jesus gives the theme and the outline of Acts in one verse: "ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me" -- in Jerusalem, Judaea, Samaria, "and unto the uttermost part of the earth." The power is not for display but for witness, and the witness radiates outward in ever-widening circles, the very map the book will follow. Human courage and cleverness cannot produce this; only the Spirit can. The mission of the church is impossible without the promised enduement, and possible only with it.
Gospel Focus
This verse is the outline of the whole book and the mission of the church: witnesses, in the power of the Spirit, spreading from Jerusalem outward to the end of the earth. The purpose of the baptism of the Holy Spirit is not merely personal blessing but power to be a witness for Christ. The gospel would not advance by human cleverness but by Spirit-empowered testimony. And the reach is total, from the home city to the ends of the earth, breaking through every barrier of nation and prejudice. The same Spirit-power that launched the church is what the church still needs to fulfill its mission. We are called to be witnesses, and the Spirit is given to make us able.
The Ascension and the Promise of Return (Acts 1:9-11)
Jesus is taken up before their eyes, and angels promise He will come again the same way.
This Same Jesus Will So Come
"Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven. Then returned they unto Jerusalem from the mount called Olivet, which is from Jerusalem a sabbath day's journey. And when they were come in, they went up into an upper room, where abode both Peter, and James, and John, and Andrew, Philip, and Thomas, Bartholomew, and Matthew, James the son of Alphaeus, and Simon Zelotes, and Judas the brother of James. These all continued with one accord in prayer and supplication, with the women, and Mary the mother of Jesus, and with his brethren. And in those days Peter stood up in the midst of the disciples, and said, (the number of names together were about an hundred and twenty,) Men and brethren, this scripture must needs have been fulfilled, which the Holy Ghost by the mouth of David spake before concerning Judas, which was guide to them that took Jesus. For he was numbered with us, and had obtained part of this ministry. Now this man purchased a field with the reward of iniquity; and falling headlong, he burst asunder in the midst, and all his bowels gushed out. And it was known unto all the dwellers at Jerusalem; insomuch as that field is called in their proper tongue, Aceldama, that is to say, The field of blood. For it is written in the book of Psalms, Let his habitation be desolate, and let no man dwell therein: and his bishoprick let another take. Wherefore of these men which have companied with us all the time that the Lord Jesus went in and out among us, Beginning from the baptism of John, unto that same day that he was taken up from us, must one be ordained to be a witness with us of his resurrection. And they appointed two, Joseph called Barsabas, who was surnamed Justus, and Matthias. And they prayed, and said, Thou, Lord, which knowest the hearts of all men, shew whether of these two thou hast chosen, That he may take part of this ministry and apostleship, from which Judas by transgression fell, that he might go to his own place. And they gave forth their lots; and the lot fell upon Matthias; and he was numbered with the eleven apostles."
Greek Study
As they watch, Jesus is "taken up" (anelemphthe, lifted up and received) and a cloud -- the cloud of divine glory -- receives Him out of sight. The two angels promise, "this same Jesus... shall so come in like manner as ye have seen him go" -- the same Jesus, in the same bodily, visible way. The One who ascended is the One who will return; the incarnation did not end at the resurrection. He remains forever the glorified God-man, now exalted to heaven and coming again.
Explanation
The ascension is not an ending but an enthronement: the risen Christ returns to the glory He had before the world was (John 17:5), now in glorified flesh. The angels gently turn the gazing disciples from the sky to their task, with the assurance that He will come again as He went. Back in Jerusalem, the waiting church gives itself to prayer and, guided by Scripture, chooses Matthias to replace Judas among the Twelve. The people who will soon turn the world upside down begin on their knees, waiting in obedient dependence for the promise.
Gospel Focus
The angels give a promise and a gentle rebuke. The disciples stand staring into the sky, but there is work to do; they are sent back to Jerusalem to wait and then to witness. And the promise is precious: "This same Jesus... will so come in like manner as you saw Him go." The One who ascended will return, personally, visibly, and bodily, the same Jesus, not a symbol or an idea. This hope steadies the church through every trial: our Lord is coming again. But until He does, we are not to stand gazing; we are to go and be His witnesses. The ascension looks up in hope and out in mission at the same time, waiting for His return while working until He comes.
Chapter 1 in Review
Acts 1 is the hinge between the gospel of Jesus and the age of the Spirit. The risen Christ commands His followers to wait in Jerusalem for the Promise of the Father, the baptism of the Holy Spirit, and promises that they will receive power to be His witnesses from Jerusalem to the end of the earth. Then He ascends before their eyes, and two angels promise that this same Jesus will return in like manner. The disciples go back to wait and pray, and choose Matthias to complete the Twelve.
For the Apostolic reader, this chapter sets the pattern for the whole book and the whole church age. The mission is impossible without the Spirit, so the first command is to wait for and receive the promised power. That power is given for witness, spreading the gospel across every barrier to the ends of the earth. And through it all shines the hope of the ascended Lord's return. Wait for the promise, receive the power, and be His witnesses until this same Jesus comes again.
- The gift of the Spirit is "the Promise of the Father," and the church must wait to receive it.
- The baptism of the Holy Spirit gives power to be witnesses, not merely personal blessing.
- The mission reaches from Jerusalem to the end of the earth, across every barrier.
- The same Jesus who ascended will return personally, visibly, and bodily.
Questions for Reflection
- Jesus told even the apostles to wait for the Spirit's power. Are you trying to serve God in your own strength?
- The Spirit's power is given for witness. Who are the "Jerusalem" and the "ends of the earth" God is sending you to?
- The angels said, "Why do you stand gazing?" Are you waiting for Christ's return in a way that also moves you to mission?
