OK. So it was a misunderstanding. We are in agreement that "once saved, always saved" is a load of nonsense.
However, I still object to two notions: (1) that you KNOW that God will save your soul (where is there room for hope?), or that (2) you KNOW that God will NOT save your soul if you do something exceedingly heinous (who are you to decide whom God will save or not?).
Yes, OSAS is a lie of the Devil. I reject all Reformed doctrines of "salvation."
1) I'm not saying one who is saved knows God will save that one, that they will endure. I'm saying one who is saved knows they are currently saved/right with God/ransomed from the power of Satan to God.
2) Shepherd of Hermas confirms what the Book of Hebrews says, that there is really virtually only one repentance for the people of God which is supposed to happen at baptism. Yes a second repentance can happen as we see examples of the Judge giving some of the 7 Assemblies in Revelation a chance to repent for doing some wicked deeds, and also Paul mentions a man who was having his father's wife as having been delivered to Satan for the destruction of the flesh that his spirit MIGHT be saved, and we know that later he was indeed restored to favor after a genuine repentance. Also the Angel of Repentance offers a chance to some to repent after they have fallen away too. But I've had lot's of chances. My conscience speaks to me that if I do such a deed that is wicked, like break my vows to my wife before God that I will most likely be given over to those twelve women in black in the Shepherd of Hermas which symbolize the fruits of apostasy. There is appointed a day in which after someone sins he can have no more forgiveness, but for heathen repentance is possible till the last day. This was common teaching in the early Church. Tertullian talks about it too (though he went a bit too far I believe). I believe that it is dangerous to not accept Hermas as Scripture because it confirms how narrow the way is and what the correct interpretation of Hebrews 6 and 10 is. AT LEAST people should take it as true if not as Scripture equal with the Bible and heed the warnings. Even certain Orthodox in the Church have had prophecies that they received and people believe them to be from God even though they don't put them in the Bible. Even 1Clement, though not in the Bible, people would agree is true and useful for doctrine. It confirms that Protestants who believe in a priesthood for all believers only are in error. But the Bible alone can prove what I'm saying because it says the Anointed One died for past sins (Romans 3:25; 2Peter 1:9), not past, present and future, so that's how the Hebrews can say what it does.
