Then Peter said to them, “Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit.” (Acts 2:38)
First, let’s notice what the people had asked Peter that provoked his response in verse thirty-eight: “What must we do?” (vs.37b). Their question appears akin to the Philippian jailer’s question in chapter sixteen, “What must I do to be saved?” (Acts 16:30b). To which Paul responded by saying, “Believe in the Lord Jesus Christ and you will be saved” (vs.31). For starters, we shouldn’t think that Luke was unaware of this contrast when he comprised this volume. Although the language Peter used in Acts 2:38 is different than that of Paul in Acts 16:31, I would argue that both are saying the same thing using different language in different contexts.
