Correct except just like NC believers the second part after the birth from above is sanctification.
Romans 8:13 For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
Now you are changing up the subject again. We are not discussing sanctification after rebirth. We are discussing circumcision of the heart whether or not it is the same as the rebirth. So after three tries I must assume you cannot defend your position. I will not try a fourth time.
Matthew 19:28 And Jesus said unto them, Verily I say unto you, That ye which have followed me, in the regeneration when the Son of man shall sit in the throne of his glory, ye also shall sit upon twelve thrones, judging the twelve tribes of Israel.
Either you honestly do not understand Matt 19:28 is speaking of the regeneration of the new heavens and new earth and not the individual regeneration spoken of the rebirth, or you think that I do not and are trying to deflect again so you do not have to answer.
Just in case you really do not know the regeneration we are speaking of, I will give you the reference which speaks to our actual subject matter....
"Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;" (Titus 3:5)
