Universalism is another way of saying the age old demonic lie: "Did God really say" ~ Satan
Easy to say. Quite something else to prove.
Jesus said
in John 3:36
"the one who rejects the Son will not see life; instead, God’s wrath remains on him."
It's 100% sure Jesus never said that, since He didn't use the English language.
Some more literal versions read:
The Emphasized Bible (Rotherham) translates the verse, "He that believes on the Son hath life age-abiding; whereas he that yieldeth not unto the Son shall not see life, but the anger of God awaiteth him."
The Emphatic Diaglott (Wilson): "He believing into the Son has aionian life; but he disobeying the Son shall not see life, but the anger of God abides on him."
Young's Literal Translation: "He who is believing in the Son hath life age-during; and he who is not believing the Son shall not see life, but the wrath of God doth remain on him."
John 3:36 He who is believing in the Son has life eonian, yet he who is stubborn as to the Son shall not be seeing life, but the indignation of God is remaining on him." (CLNT)
This means as long as the stubborn remain stubborn or unbelieving they will not see eonian life.
It does not mean that the unbeliever or stubborn cannot change and become a believer. If that were true, then no one could be saved, because we were all stubborn and unbelievers at one point.
It does not deny that all will eventually believe & have their sins taken away. On the contrary the same writer already wrote two chapters before:
1:29 The next day John saw Jesus coming toward him and said, “Look, the Lamb of God, who takes away the sin of the world!
In chapter 4 he writes:
39 Many of the Samaritans from that town believed in him because of the woman’s testimony, “He told me everything I ever did.” 40 So when the Samaritans came to him,
they urged him to stay with them, and he stayed two days. 41 And because of his words many more became believers.
42 They said to the woman, “We no longer believe just because of what you said; now we have heard for ourselves, and we know that this man really is the Savior of the world.”
John 3:36 does not say a person can only believe in this life time. Or that God's love runs out when a person dies.
The early church father, Origen, speaks of what is "after eonian life" (mistranslated in the KJV "eternal life"):
"...in a passage in Origen in which he speaks of “life after aionios life” (160). As a native speaker of Greek he does not see a contradiction in such phrasing; that is because aionios life does not mean “unending, eternal life,” but rather “life of the next age.” Likewise the Bible uses the word kolasis to describe the punishment of the age to come. Aristotle distinguished kolasis from timoria, the latter referring to punishment inflicted “in the interest of him who inflicts it, that he may obtain satisfaction.” On the other hand, kolasis refers to correction, it “is inflicted in the interest of the sufferer” (quoted at 32). Thus Plato can affirm that it is good to be punished (to undergo kolasis), because in this way a person is made better (ibid.). This distinction survived even past the time of the writing of the New Testament, since Clement of Alexandria affirms that God does not timoreitai, punish for retribution, but he does kolazei, correct sinners (127)."

Because I have sinned against him,I will bear the Lord's WRATH, UNTIL he pleads my case and upholds my cause. He will bring me out into the light; I will see his righteousness.(
Micah 7:9)
AS in Adam ALL die SO ALSO in Christ shall ALL be made alive (1 Cor.15:22)
1 Cor 15:28 When he has done this, then the Son himself will be made subject to him who put everything under him, so that God may be all in all.
Lamentations 3:22 and 3:31-33, The steadfast love of the Lord NEVER ceases, his mercies NEVER come to an end. . . .
Lam.3:31 For the Lord will NOT cast off FOR EVER:
32 For if He causes grief, Then He will have compassion According to His abundant lovingkindness. 33 For He does not afflict willingly Or grieve the SONS OF MEN.…

Jesus said in John 5:28-29
“Do not be amazed at this, for a time is coming when all who are in their
graves will hear his voice and come out—those who have done what is good
will rise to live, and those who have done what is evil will rise to be
condemned."
New American Standard Bible
Jn.5:29 and will come forth; those who did the good deeds to a resurrection of life, those who committed the evil deeds to a resurrection of JUDGEMENT.

When your judgments come upon the earth, the people of the world learn righteousness." (Isa.26:9b)
