Perhaps His warning has the desired effect.
It's just a theory anyway, in light of the many verses that proclaim universalism (I know you disagree).
If all be reconciled to God in Christ, then there can't be a bunch of unforgiven people left.
Why are none of the UR proof texts found where Jesus was speaking?
And the ones from the apostles are contradicted by the same apostles own writing.
E.g. Paul.
Col 1:20 and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross.
Colossians 1:20 which supposedly says all things on earth will be reconciled, righteous and unrighteous alike, even after death, no matter what. But 2 vss. later vs. 23, Paul says there are conditions
Col 1:23
(23)IF ye continue in the faith grounded and settled, and be not moved away from the hope of the gospel, which ye have heard, and which was preached to every creature which is under heaven; whereof I Paul am made a minister;
The condition is IF you continue in the faith etc. The converse of vs. 23 “if you do NOT continue in your faith [are] NOT grounded and NOT settled, and ARE moved away from the hope of the gospel, you will NOT be reconciled [vs. 20][/color]
Let us read more from Paul about UR.
● 1 Corinthians 6:9-10
(9) Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neitherfornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
(10) Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.
● Galatians 5:19-21
(19) Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
(20) Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
(21) Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall NOT inherit the kingdom of God.
● Ephesians 5:3-5
(3) But fornication, and all uncleanness, or covetousness, let it not be once named among you, as becometh saints;
(4) Neither filthiness, nor foolish talking, nor jesting, which are not convenient: but rather giving of thanks.
(5) For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God.
In three different epistles [books] Paul lists groups of people who do not have any inheritance in the kingdom of heaven. Please show a verse, 2 or more would be better, where Paul says “Oops I made a mistake, all these people will be reconciled even if they were sinful and unrighteous when they died.
Here are more verses which state conditions for salvation.
Romans 8:13 For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
1 Corinthians 15:2
(2) By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.
Luke 10:13-15
(13) Woe unto thee, Chorazin! woe unto thee, Bethsaida! for if the mighty works had been done in Tyre and Sidon, which have been done in you, they had a great while ago repented, sitting in sackcloth and ashes.
(14) But it shall be more tolerable for Tyre and Sidon at the judgment, than for you.
(15) And thou, Capernaum, which art exalted to heaven, shalt be thrust down to hell.
Luke 17:1 Then said he unto the disciples, It is impossible but that offences will come: but woe unto him, through whom they come!
Luke 17:2 It were better for him that a millstone were hanged about his neck, and he cast into the sea, than that he should offend one of these little ones.
Lk 17:1 A fate worse than death, no salvation
Luke 20:46 Beware of the scribes, which desire to walk in long robes, and love greetings in the markets, and the highest seats in the synagogues, and the chief rooms at feasts;
Luke 20:47 Which devour widows' houses, and for a shew make long prayers: the same shall receive greater damnation.
Greater damnation, not salvation.
Luke 3:4-6
(4) As it is written in the book of the words of Esaias the prophet, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
(5) Every valley shall be filled, and every mountain and hill shall be brought low; and the crooked shall be made straight, and the rough ways shall be made smooth;
(6) And all flesh shall see the salvation of God.
In these vss. Luke is quoting Isaiah 40:4-5 but Luke misquoted the word salvation for glory.
Isaiah 40:4-5
(4) Every valley shall be exalted, and every mountain and hill shall be made low: and the crooked shall be made straight, and the rough places plain:
(5) and the glory [כבוד /kabod] ]of the LORD shall be revealed, and all flesh shall see it together: for the mouth of the LORD hath spoken it.
What or who is the salvation that Paul said all flesh would see? c.f. Luk 2:30.
Luk 2:27-30
(27) And he came by the Spirit into the temple: and when the parents brought in the child Jesus, to do for him after the custom of the law,
(28) Then took he him up in his arms, and blessed God, and said,
(29) Lord, now lettest thou thy servant depart in peace, according to thy word:
(30) For mine eyes have seen thy salvation[ ישועה/yeshuah] pronounced the same as Yeshua/ישוע Jesus’ name in Hebrew.
