Anyone being baptized upon that name would be publicly declaring allegiance to Jesus as the Messiah. Notice that Peter promises forgiveness of sin and the gift of the Holy Spirit to any who enter into that commitment. for forgiveness of sins, and you will receive the gift of the Holy Spirit. 39 For the promise is to you, and to your children, and to all who are far away*I assume that "all who are far away" is a reference to Gentiles, and the promise applies only to the ‘called’.—as many, that is, as the Lord our God may call."
