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.
Unto obedience and sprinkling of the blood of Jesus Christ - This expresses the design for which they had been chosen by the Father, and renewed by the Spirit. It was that they might obey God, and lead holy lives. On the phrase “unto obedience,” see the notes at Romans 1:5. The phrase “unto sprinkling of the blood of Jesus Christ,” means to cleansing from sin, or to holiness, since it was by the sprinkling of that blood that they were to be made holy. See it explained in the notes at Hebrews 9:18-23; Hebrews 12:24.
