Acts 2:38
Peter replied, 'Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit. — repentance (metanoia, turning around, change of mind and direction) is the first step toward salvation. Baptism in Jesus' name (onoma, name, identity, authority) signifies allegiance and identification with Christ. Forgiveness of sins (aphesis, release, remission, cancellation) is the transaction's benefit: sins are declared canceled, removed, no longer held against the believer. The Spirit is promised as the gift (dorea, gift, present) following faith-response.
