Nice try you will not find any verse stating they were regenerate ( born again ) until Pentecost.
And I can prove to you they did not understand spiritual things and especially the gospel until after Jesus Resurrection from the dead. They were carnal/natural and not spiritual when they were with Jesus during those three years. Jesus had to take them aside all of the time to explain the parables. Even then they did not understand.
The disciples did not understand the death, burial and resurrection of Jesus which is the gospel. They did not believe it until they physically saw Jesus Resurrected from the dead.
Matthew 16:8-11
Aware of their discussion, Jesus asked, “You of little faith, why are you talking among yourselves about having no bread? 9
Do you still not understand? Don’t you remember the five loaves for the five thousand, and how many basketfuls you gathered? 10 Or the seven loaves for the four thousand, and how many basketfuls you gathered? 11
How is it you don’t understand that I was not talking to you about bread?
Mark 7:18
And he saith unto them
, Are ye so without understanding also? Do ye not perceive, that whatsoever thing from without entereth into the man,
it cannot defile him;
Mark 8:31-33
He then began to teach them that the Son of Man must suffer many things and be rejected by the elders, the chief priests and the teachers of the law, and that he must be killed and after three days rise again. 32 He spoke plainly about this,
and Peter took him aside and began to rebuke him. 33 But when Jesus turned and looked at his disciples, he rebuked Peter.
“Get behind me, Satan!” he said. “You do not have in mind the concerns of God, but merely human concerns.”
Luke 9:43-45
While everyone was marveling at all that Jesus did, he said to his disciples, 44 “Listen carefully to what I am about to tell you: The Son of Man is going to be delivered into the hands of men.” 45
But they did not understand what this meant.
It was hidden from them, so that they did not grasp it, and they were afraid to ask him about it.
Jesus predicts His death a 3rd time
Luke 18:31-34
Jesus took the Twelve aside and told them, “We are going up to Jerusalem, and everything that is written by the prophets about the Son of Man will be fulfilled. 32 He will be delivered over to the Gentiles. They will mock him, insult him and spit on him; 33 they will flog him and kill him. On the third day he will rise again.”
34
The disciples did not understand any of this. Its meaning was hidden from them, and they did not know what he was talking about.
Luke 24:25-26
He said to them,
“How foolish you are, and how slow to believe all that the prophets have spoken!
26 Did not the Messiah have to suffer these things and then enter his glory?
John 7:39
By this he meant the Spirit, whom those who believed in him were later to receive. Up to that time the Spirit had not been given, since Jesus had not yet been glorified.
John 12:16
At first His disciples did not understand these things, but after Jesus was glorified they remembered what had been done to Him, and they realized that these very things had also been written about Him.
John 13
Jesus replied, “You do not realize now what I am doing,
but later you will understand…. I am telling you now before it happens, so that when it does happen you will believe that I am who I am.”
Jesus promised the disciples He would bring to their remembrance when Pentecost came and the Holy Spirit would be in them and guide them into all truth.
John 14:26
But the Comforter,
which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you
John 16:7
"It is expedient for you that I go away; for if I go not away the Comforter will not come unto you; but if I depart I will send him unto you."
John 16:13
But when he, the Spirit of truth, comes, he will guide you into all the truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come.
