To them it was revealed, that not to themselves, but to you, did they minister these things, which now have been announced to you through those who preached the Gospel to you by the Holy Spirit sent out from heaven; which things angels desire to look into.

 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.
