Peter, an apostle of Jesus Christ, to the chosen ones who are living as strangers in the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia,
Unto obedience and sprinkling of the blood of Christ ...  The "obedience" in view here is the continuing fidelity of the Christian, not his primary obedience, because that must precede the Christian's endowment with the Spirit.  The Spirit's being the agent of this continuing obedience unto sanctification "wholly," proves that the initial steps of accepting and obeying the gospel are not meant, because no one ever made it any clearer than did Peter that people must believe, repent and be baptized "in order to receive" and before they can ever receive, the promise of the Spirit (Acts 2:38ff).
