What’s remarkable Revival is that you totally ignored my post and only restated your opening point, and then go on to quote Heb. 10.29 which is not speaking of the punishment of unbelievers, but of believers who continue in deliberate sin, and Heb. 12:5-8 which says that such punishment is from God and for the good of the one being punished. So if anything, your scriptural references only affirm UR and disprove your assertion, even equating in context the word timoria with remedial punishment.
Heb. 10: 26 If we deliberately keep on sinning after we have received the knowledge of the truth, no sacrifice for sins is left, 27 but only a fearful expectation of judgment and of raging fire that will consume the enemies of God. 28 Anyone who rejected the law of Moses died without mercy on the testimony of two or three witnesses. 29 How much more severely do you think someone deserves to be punished who has trampled the Son of God underfoot, who has treated as an unholy thing the blood of the covenant that sanctified them, and who has insulted the Spirit of grace? 30 For we know him who said, “It is mine to avenge; I will repay,” and again, “The Lord will judge his people.” 31 It is a dreadful thing to fall into the hands of the living God.
Heb. 12: 4 In your struggle against sin, you have not yet resisted to the point of shedding your blood. 5 And have you completely forgotten this word of encouragement that addresses you as a father addresses his son? It says,
“My son, do not make light of the Lord’s discipline,
and do not lose heart when he rebukes you,
6 because the Lord disciplines the one he loves,
and he chastens everyone he accepts as his son.”
