If you are referring to your 5133, I had no idea what you were talking about then, and I still do not now. Who has ever said that the OT Jews who were of the elect were sent to hell? I will be happy to try to answer any question, but I really have no clue where you are coming from.
The Apostle's Creed, for starters. David, Job, the Psalmists all went to the Hades (Sheol). Perhaps Genesis 37:34-35 "
So Jacob (A)tore his clothes, and put sackcloth on his loins and mourned for his son many days.
Then all his sons and all his daughters arose to comfort him, but he refused to be comforted. And he said, "Surely I will go down to Sheol in mourning for my son." So his father wept for him.
From the OT readings it is clear that no one comes back from it until the Lord resurrects them:
Or Job 14:13 -- the righteous Job knew he was going to Sheol.
Now, you said that the OT righteous believed in the future Chirst. But all Jews believed that God is the ultimate Savior, except that they believed only in what we would call God the Father. Isa 43:11 "I, even I, am the LORD, And there is no savior besides Me."
So, when I say that all Jews believe in the same God as we do, then all those who believed, by faith alone, should have been saved, even if they did not believe in Chirst, even if they did not see Christ as the same God.
According to you, only those who believe in Jesus can be saved. That means that those who were OT righteous could not be saved, which is why they were in the Sheol and had to be rescued by Christ. But if they were righteous, why did they need rescuing? Obviously, faith alone does not save, for the righteous, including David and a "perect man" in God's eyes -- Job had -- all had the faith, yet they were not spared. They all went down and had to be rescued by Christ.
