1) "Then Peter said unto them," (Petros de pros autous) "Then Peter (responded) to them," to the unsaved Israelite brethren who had asked, "What may we do?" In the light of their guilt, remorse, pricked hearts, and heavy conscience Peter proceeded to tell them two things: 1. First how they could be or become right before an offended God, and 2. Second how they could become right before the world before whom they had murdered their own Redeemer.
2) "Repent," (metanoesate) "You all repent;” The "you all" refers to all who had asked what they might do- -not just to be saved, but also to have a right testimony before the world. The second person plural "you all’ were commanded to repent, Luke 13:3; Luke 13:5; Acts 3:19 for repentance brings conversion into life, Acts 11:18.
3) "And be baptized every one of you," (kai baptistheto hekatos humon) "And let each one of you (individually), who has repented, (or been converted unto life) be baptized," only those who have repented unto God, and placed faith in the crucified one, those who in repentance have been converted unto life are exhorted to be baptized, that they may be identified as followers of the one against whom they once stood as enemies.
4) "In the name of Jesus Christ,"(epi to onomati lesou Christous) "Relying upon the name of Jesus Christ," by the authority of Jesus Christ, as authorized, approved by Jesus Christ; He authorized and approved for baptism only such as had first become converted, disciples, received forgiveness of sins, and become His children, Matthew 28:18-20.
5) "For the remission of sins," (eis aphesin ton hamartion humon) "With reference to the forgiveness of your sins;” The Greek “eis” means "with reference to" remission of sins for each of you who has repented, it is becoming that each of you be baptized to acknowledge that you have received and desire to follow Jesus Christ whom you crucified.
6) "And ye shall receive," (kai lempsesthe) "And you all will receive (of your own accord), by virtue of your own choice, the Holy Spirit, 1 John 4:13; Romans 5:5. The erroneous idea of baptismal regeneration is not alluded to in any manner in this passage. It is by the Holy Spirit one is begotten to eternal life when he repents or believes in Jesus Christ, John 6:63; 1 John 5:1.
7) "The gift of the Holy Ghost." (ten dorean tou hagion pneumatos) "The gift of the Holy Spirit," which comes to one in regeneration, in the new birth, to abide in and with Him forever, even as He came on Pentecost to abide with and empower the church forever, John 14:16-17; Acts 1:8; Acts 2:1-4.
This passage, when taken in contextual setting, has no enigmas, hidden mysteries, or complex meanings. Nor is it necessary for one to be a Greek Scholar or Oriental mystic to set forth its basic meaning.
Under the gospel witnessing of the Holy Ghost Power which had comedown to the church and upon the church, as the Promised comforter, the church had witnessed of Jesus Christ in power in tongues and dialects understood by Jews from three continents and more than fifteen nations.
In this context Peter charged that the Israelites (Jews) with wicked hands had crucified the promised Redeemer who had been resurrected, met with them, then ascended to heaven, awaiting the hour when He would return to judge all men, including them for their wicked deeds. Under the gospel witnessing and judgement preaching of Peter they cried out, "what shall or should we do?" Peter responded by telling them that they should all do two things: 1 ) First, all should, and he imperatively commanded them, "you all repent," Second person active plural. This was that they might have their sins remitted, be converted, or be granted eternal life, Acts 3:19; Acts 11:18; Acts 17:30-31; 2 Corinthians 7:10.
2) Second, to all who repent, were converted, he added, "Let each of you be baptized with reference to remission of your sins," "each of you" is third person singular and "be baptized" is passive; Then each too would receive the gift or benefit of the gift of the Holy Ghost upon the church forever, John 14:16-17.
