When Christ commissioned the twelve apostles He foretold them:
But beware of men: for they will deliver you up to
councils, and in their
synagogues they will scourge you; yea and
before governors and kings shall ye be brought for my sake, for a testimony to them and to the Gentiles. But when they deliver you up,
be not anxious how or what ye shall speak: for it shall be given you in that hour what ye shall speak. For it is not ye that speak, but the Spirit of your Father that speaketh in you. Mt 10:17-20
In the Olivet Discourse He foretold them:
But before all these things, they shall lay their hands on you, and shall persecute you, delivering you up to the
synagogues and prisons, bringing you
before kings and governors for my name`s sake. It shall turn out unto you
for a testimony. Settle it therefore in your hearts, not to meditate beforehand how to answer: for
I will give you a mouth and wisdom, which all your adversaries shall not be able to withstand or to gainsay. Lk 21:12-15
In the Farewell Discourse He foretold them:
They shall put you out of
the synagogues: yea, the hour cometh, that whosoever killeth you shall think that he offereth service unto God.....And he,
when he [the Comforter] is come, will convict the world in respect of sin, and of righteousness, and of judgment: of sin, because they believe not on me; of righteousness, because I go to the Father, and ye behold me no more; of judgment, because the prince of this world hath been judged. Jn 16:2, 8-11
20 Jesus answered him, I have spoken openly to
the world; I ever taught in
synagogues, and in
the temple, where all
the Jews come together; and in secret spake I nothing. Jn 18
How did the Comforter who came after Christ died "convict the world.
Through the testimony of His witnesses:
Acts 2:
….
they were all filled with the Holy Spirit, and began to speak with other tongues,
as the Spirit gave them utterance…Ye men of Israel, hear these words:
Jesus of Nazareth… ye by the hand of lawless men did crucify and slay…God hath made him both Lord and Christ, this
Jesus whom ye crucified. Acts 2:4,22,23,36
Acts 3:
…Peter… answered unto the people, Ye men of Israel…
his Servant Jesus; whom
ye delivered up, and denied before the face of Pilate, when he had determined to release him…
ye denied the Holy and Righteous One,
and asked for a murderer to be granted unto you,
and killed the Prince of life…
whereof we are witnesses. Acts 3:12-15
Acts 4:
…
Peter, filled with the Holy Spirit, said unto them, Ye rulers of the people, and elders… be it known
unto you all, and to all the people of Israel, that in the name of
Jesus Christ of Nazareth, whom ye crucified… Acts 4:8,10
Acts 5:
… they set them before the council…. ye have filled Jerusalem with your teaching, and
intend to bring this man`s blood upon us….
Peter and the apostles answered and said… The God of our fathers raised up
Jesus, whom ye slew, hanging him on a tree…
we are witnesses of these things; and so is the Holy Spirit Acts 5:27,28,29,30,32
Acts 6 & 7:
…there arose certain of
them that were of the synagogue called the synagogue of the Libertines, and of the Cyrenians, and of the Alexandrians, and of them of Cilicia and Asia,
disputing with Stephen. And they were not able to withstand the wisdom and the Spirit by which he spake….Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Spirit:
as your fathers did, so do ye. Which of the prophets did not your fathers persecute? and they killed them that showed before of the coming of
the Righteous One; of whom ye have now become betrayers and murderers; Acts 6:9,10; Acts 7:51,52
Acts 10:
…
we are witnesses of all things which he did both in the country of the Jews, and in Jerusalem; whom also they slew, hanging him on a tree…. Him God raised up the third day, and gave him to be made manifest, not to all the people, but unto
witnesses that were chosen before of God, even to us, who ate and drank with him after he rose from the dead. And he charged us to preach unto the people, and to testify that this is he who is ordained of God to be the Judge of the living and the dead. Acts 10: 39-42
Acts 13:
…Paul stood up, and beckoning with the hand said, Men of Israel, and ye that fear God, hearken…
they that dwell in Jerusalem, and their rulers, because they knew him not, nor the voices of the prophets which are read every sabbath, fulfilled them by
condemning him. And though they
found no cause of death in him, yet
asked they of Pilate that he should be slain. And when they had fulfilled all things that were written of him, they took him down from the tree, and laid him in a tomb. But God raised him from the dead: and
he was seen for many days of them that came up with him from Galilee to Jerusalem, who are now his witnesses unto the people. Acts 13:16,27-31
I see the claim all those seeking had been made alive, regenerated. The rich young ruler was seeking yet was not saved. Those of Matthew 23:13 were seeking yet were not saved. The claim is unbiblical.
You really gom things up when you conflate the heavenly birth with conversion.
Before one can enter or even see the kingdom of God one must first be born from above. Jn 3:3,5
