I don't "
rail" against anything. I express my understanding as cordially as possible and expect the same in return. Which OBTW I am not getting here. I don't have to read any books on UR by learned scholars with letters after their names. I can read the Bible for myself in 5 languages. I have a Masters degree from the flagship seminary of my chosen denomination. And have been engaged in pastoral ministry for 59 years.
"Really the main difference is we believe that God is a loving Father and he can and will give people a way to repent after their mortal body is dead, that’s really the only difference."
The vss. which I present to counter the quoted statement.
Jeremiah 13:10-11
(10) This evil people, which refuse to hear my words, which walk in the imagination of their heart, and walk after other gods, to serve them, and to worship them, shall even be as this girdle, which is good for nothing.
(11) For as the girdle cleaveth to the loins of a man, so have I caused to cleave unto me the whole house of Israel and the whole house of Judah, saith the LORD; that they might be unto me for a people, and for a name, and for a praise, and for a glory: but they would not hear.
Jeremiah 13:14
(14) And I will dash them one against another, even the fathers and the sons together, saith the LORD: I will not pity, nor spare, nor have mercy, but destroy them.
Salvation is never mentioned after this.
Matthew 7:21-23
(21) Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
(22) Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
(23) And then will I [Jesus] profess unto them, I never knew you: depart from me, ye that work iniquity.
When Jesus says never He does not mean someday by and by.
Revelation 21:4
(4) And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
No more death.
Revelation 22:11
(11) He that is unjust, let him be unjust still: and he which is filthy, let him be filthy still: and he that is righteous, let him be righteous still: and he that is holy, let him be holy still.
No more salvation.
Revelation 22:15
(15) For without [outside new Jerusalem] are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie.
