according to the foreknowledge of God the Father, in sanctification of the Spirit, that you may obey Jesus Christ and be sprinkled in his blood: Grace to you and peace be multiplied.

 It is in the purpose of God that the Christian is called. It is by the work of the Holy Spirit that his life is hallowed towards God. It is by the sprinkling of the blood of Christ that he is cleansed from past sin and dedicated to future obedience to God.
