What does 'Repent' mean ?

Isnt the ' stony heart , replaced by a fleshy heart ,about Israel in the future?

////
that can be pricked by God to feel guilty when he has broken a spiritual law///// Which verse says this?
And Rom 2.14
For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves:

It is about regeneration for people from every kindred, and tongue, and people, and nation, Rev 5:9. At regeneration, God puts the Holy Spirit within a person. This process of being born again has been happening the same way sense the beginning of time, from the old testament through the new testament. Isaiah 63:11, Then he remembered the days of old, Moses, and his people, saying, Where is he that brought them up out of the sea with the shepherd of his flock? where is he that PUT HIS HOLY SPIRIT WITHIN HIM?

In Acts 2, on the day of pentecost, Peter was preaching about some Jews, blaming them for crucifying Jesus, and some of them, were PRICKED in the heart (the fleshy heart that can be pricked) and said men, and brethren, what must we do?

In contrast when Steven was preaching the same sermon, some of the Jews with the stony heart, were CUT to the heart, and stoned Steven to death.

What is everyone's opinion on Ray Comfort ? Many say he is preaching Lordship salvation with the way he teaches " there's two things you have to do to be saved. You have to repent and believe. When he explains repentance he will sometimes say " turn from sins " ?

My understanding is that repentance simply means ' change of mind ' .
It could also be breaking frame from a current set of propositions.

Jesus gives an example of repentance being a change of mind in Mathew 21 .
28¶But what think ye? A certain man had two sons; and he came to the first, and said, Son, go work to day in my vineyard.
29He answered and said, I will not: but afterward he REPENTED AND WENT.
30And he came to the second, and said likewise. And he answered and said, I go, sir: and went not.
31Whether of them twain did the will of his father? They say unto him, The first. Jesus saith unto them, Verily I say unto you, That the publicans and the harlots go into the kingdom of God before you.
32For John came unto you in the way of righteousness, and ye believed him not: but the publicans and the harlots believed him: and ye, when ye had seen it, repented not afterward, that ye might believe him.
So we see two things . He repented ( changed his mind and went . So repenting isn't the action its the changing of mind .

Thoughts?
Agree ?
Disagree ?

Paul was pricked with the thorns of the gospel .The letter of the law (death) it woke him up to the grace, the law of faith that worked in him to both will and do the good pleasure of God.

The thorn in the flesh takes away the desire to glory in the flesh. It can lead to blindness .

2 Corinthians 12:6-8 King James Version (KJV) For though I would desire to glory, I shall not be a fool; for I will say the truth: but now I forbear, lest any man should think of me above that which he seeth me to be, or that he heareth of me.
And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure.

The work of Christ who first repents

In the context of Peter speaking to "ye men of Israel" (Acts 3:12+), I think he uses "repent" in the sense of "changing their minds as to His [/Jesus'] identity"

(i.e. He truly is their promised Messiah... He came [first] as "Suffering Servant [vv.13,26]," which aspect they had overlooked/bypassed in their "expectations" from OT scripture, thus themselves fulfilling that very thing [His rejection and death on the Cross], but which aspect Peter is pointing out how the OT prophets "from Samuel and those that follow after, ... have foretold OF THESE DAYS" [v.24, speaking of His "Suffering Servant" days--first advent/earthly ministry before and including the Cross--See Samuel 8:7 and compare with what Jesus said in Luke 19:14 and what was said about Joseph's FIRST dream [reflective of Jesus' FIRST advent], in Genesis 37:7-8]).


Yes, calling for a "change of mind" concerning His IDENTITY.

Could you find a verse thats not about Israel that says Gentiles in 2020 get a new fleshy heart and a stone heart removed?

There could be many messages that ' prick ' peoples hearts that simply mean they responded that way upon hearing . Why are you adding more than necessary to the text . ?

Its simply saying they responded . Thats all . It happens today . I respond to my gas bill , Tax bill , good news , bad news . One man responds with Anger to a message ,another apathy ,another rejoice , indifference, remorse, ect

Only his sheep (regenerated children of God) can hear his voice, and he gives unto them eternal life. Why do you try to reject some scriptures that do not fit your misguided theory?
