Hi
I found this letter that was written by John Piper to another man. He states some of the things that I too see. This is but a short excerpt from the letter.
"
2) Stephen makes a very suggestive comment to the Jews of the post-Pentecost period: “You hard necked and uncircumcised in heart and ears, you are always resisting the Holy Spirit, as your fathers, so also you” (
Acts 7:51). Does this not mean that Stephen and Luke thought of generation after generation of Jews resisting the Holy Spirit just as the Jews of the post-Pentecost era did?
3) Paul picks up the motif of the “uncircumcised heart” and says that (true) circumcision is of the heart, just like being a (true) Jew is a secret matter of the heart (
Romans 2:28ff). In other words, these terms correspond to the “new creature” or “new man”; they mark off the truly new person who is in saving fellowship with God.
But I would argue that Paul is simply repeating a truth that the Old Testament made plain. In
Deuteronomy 10:16 Moses appeals, like Stephen, “Circumcise then your
heart and stiffen your neck no more.” What
in reality was he calling for? Or hear
Jeremiah 4:4, “Remove the foreskin of your
hearts!” Or
Ezekiel 18:31, “Cast away from you all your transgressions which you have committed and make yourselves a
new heart and a
new spirit!”"

What is regeneration if it is not, co-operating with the Holy Spirit, circumcision of the heart, a new heart and a new spirit?
How can this happen but by the grace through faith?
