There is no mention in the New Covenant of any believer requiring RE-BAPTISM or being SAVED AGAIN because neither is necessary.
John 4:13 Whosoever drinketh of this water shall thirst again.
The PUNCTILIAR, one time, Greek AORIST action of "drink" in John 4:13 secures the eternal spring of the HOly Spirit. Otherwise, "NEVER" is a lie and a sin by Jesus (God forbid).
John 4:13. Apekrithe Iesous kai eipen aute, "Pas ho pinon ek tou hudatos toutou dipsesei palin.
Russ, the Greek word translated “drinketh” in John 4:13 is not an aorist verb! It is a present participle. Perhaps you mean the cognate verb in John 4:14 where the tense is the active aorist in the subjunctive mood.
John 4:14. Hos dan pie ek tou hudatos hou ego doso auto, ou-medipsesei eis ton aiona! Alla to hudor ho dosoauto genesetai en auto pege hudatos hallomenou eiszoen aionion!"^
John 4:13. Jesus answered and said to her, "Everyone who drinks of this water will thirst again;
14. but whoever drinks of the water that I will give him shall never thirst; but the water that I will give him will become in him a well of water springing up to eternal life." (NASB, 1995)
Again, the context is very important to the correct understanding of verses 13-14:
5. So He *came to a city of Samaria called Sychar, near the parcel of ground that Jacob gave to his son Joseph;
6. and Jacob's well was there. So Jesus, being wearied from His journey, was sitting thus by the well. It was about the sixth hour.
The Woman of Samaria
7. There *came a woman of Samaria to draw water. Jesus *said to her, "Give Me a drink."
8. For His disciples had gone away into the city to buy food.
9. Therefore the Samaritan woman *said to Him, "How is it that You, being a Jew, ask me for a drink since I am a Samaritan woman?" (For Jews have no dealings with Samaritans.)
10. Jesus answered and said to her, "If you knew the gift of God, and who it is who says to you, 'Give Me a drink,' you would have asked Him, and He would have given you living water."
11. She *said to Him, "Sir, You have nothing to draw with and the well is deep; where then do You get that living water?
12. "You are not greater than our father Jacob, are You, who gave us the well, and drank of it himself and his sons and his cattle?"
13. Jesus answered and said to her, "Everyone who drinks of this water will thirst again;
14. but whoever drinks of the water that I will give him shall never thirst; but the water that I will give him will become in him a well of water springing up to eternal life."
15. The woman *said to Him, "Sir, give me this water, so I will not be thirsty nor come all the way here to draw."
16. He *said to her, "Go, call your husband and come here."
17. The woman answered and said, "I have no husband." Jesus *said to her, "You have correctly said, 'I have no husband';
18. for you have had five husbands, and the one whom you now have is not your husband; this you have said truly."
19. The woman *said to Him, "Sir, I perceive that You are a prophet.
20. "Our fathers worshiped in this mountain, and you
people say that in Jerusalem is the place where men ought to worship."
21. Jesus *said to her, "Woman, believe Me, an hour is coming when neither in this mountain nor in Jerusalem will you worship the Father.
22. "You worship what you do not know; we worship what we know, for salvation is from the Jews.
23. "But an hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth; for such people the Father seeks to be His worshipers.
24. "God is spirit, and those who worship Him must worship in spirit and truth."
25. The woman *said to Him, "I know that Messiah is coming (He who is called Christ); when that One comes, He will declare all things to us."
26. Jesus *said to her, "I who speak to you am
He. "
27. At this point His disciples came, and they were amazed that He had been speaking with a woman, yet no one said, "What do You seek?" or, "Why do You speak with her?"
28. So the woman left her waterpot, and went into the city and *said to the men,
29. "Come, see a man who told me all the things that I
have done; this is not the Christ, is it?"
30. They went out of the city, and were coming to Him.
We see here that Jesus is sharing the Gospel with the woman at the well and He tells her about the Baptism in the Holy Spirit. Certainly the Baptism in the Holy Spirit is a PUNCTILIAR event rather than a CONTINUOUS process, but the Bible tells us very clearly that being baptized in the Holy Spirit does not guarantee that the one who receives the baptism will be faithful to Christ nor does it guarantee that the one who receives it will be saved in the end.
1 Cor. 10:1. For I do not want you to be unaware, brethren, that our fathers were all under the cloud and all passed through the sea;
2. and all were baptized into Moses in the cloud and in the sea;
3. and all ate the same spiritual food;
4. and all drank the same spiritual drink, for they were drinking from a spiritual rock which followed them; and the rock was Christ.
5. Nevertheless, with most of them God was not well-pleased; for they were laid low in the wilderness.
6. Now these things happened as examples for us, so that we would not crave evil things as they also craved.
7. Do not be idolaters, as some of them were; as it is written, "THE PEOPLE SAT DOWN TO EAT AND DRINK, AND STOOD UP TO PLAY."
8. Nor let us act immorally, as some of them did, and twenty-three thousand fell in one day.
9. Nor let us try the Lord, as some of them did, and were destroyed by the serpents.
10. Nor grumble, as some of them did, and were destroyed by the destroyer.
11. Now these things happened to them as an example, and they were written for our instruction, upon whom the ends of the ages have come.
12. Therefore let him who thinks he stands take heed that he does not fall. (NASB, 1995)
