As pointed out above...
The Church Fathers on Universalism
Maybe God judges immediately, but Heb. 9:27 doesn't say or even imply "immediately". It just says "after". That could be immediately after death or that could be years after death.
*Gehenna* is commonly translated “hell.” Gehenna is derived from a valley nearby Jerusalem that originally belonged to a man named Hinnom. “This was a valley near Jerusalem, and appears to have held this name perhaps as far back as the time of Joshua. This valley was used by the more idolatrous kings of Judah as a place where they would sacrifice their own children to the god Moloch. It may also have been the location where, in a single night, the Messenger of Yahweh killed a massive number of Assyrians from the army of Sennacherib. Going from there, it was traditionally associated with the location Isaiah refers to in his final chapter ('they shall go out' implies exiting Jerusalem into the valley), where *dead* bodies are devoured by unquenchable fire (i.e. fire that does not stop burning until it has completely consumed everything in its path) and undying worms (i.e. the maggots that unceasingly feast upon corpses). In ancient Aramaic translations of this chapter of Isaiah, the dead bodies are explicitly stated to be in the Valley of Hinnom, where the wicked suffered the 'second death'. Jesus confirms the traditional association by describing the Valley of Hinnom in the same way Isaiah describes the location filled with unquenchable fire and maggots. The Valley of Hinnom is only ever used by Jesus (with a single, extraneous usage by James) when speaking to his fellow Jews. He uses it especially when warning them about sinning unrepentantly. Jesus uses the Valley of Hinnom because it had become a common symbol for God's divine punishment. In this sense, it is analogous to the lake of fire (especially since both are referred to as the 'second death'). According to Jesus, God is able to destroy both body and soul in the Valley of Hinnom.” (“The History of Hell” by Mark Edward). See Joshua 18:16, 2 Kings 23:10 and 2 Chron. 33:6. I’d like to emphasize Luke 12:5 where it states that *after* God has killed the wicked ones, He has authority to cast the wicked *dead* into “hell” (actually, Gehenna), which is why it is called the “second death”—the dead body goes through a second death in the unquenchable fire that devours the dead body until it has been completely consumed.
That's nations. *And* the goats are separated because of their lack of *works* (i.e. feeding hungry, clothing poor) during the tribulation that was imminent. So unless you're a works-salvation person, this should make you rethink what Jesus is talking about here. It's not about the final judgment at Jesus' physical return.
Same as above. It's about AD 70.
Same as above. Jesus' primary mission was to warn those living at the time to repent for the kingdom was at hand. Destruction was coming. And did come.
And he called Peter Satan. So, you're wrong about your literal take on that.
That's just a figure of speech. Sinners are outside the gates that are always open. That means God can still work to redeem them. That may be offensive to some but that's what can be gleaned from many scriptures. I remain hopeful. I see a God who can do the unthinkable, the unimaginable...the God of surprises.
That phraseology--children of devil, lost sheep, goat nations--was first and foremost for AD 70 folks. We can still take the lessons but that wasn't written to us living in 2017.
Which people go through here and now who don't experience God.
It doesn't imply "forever dying" in the slightest. As a matter of fact, if you take just the OT, one would have to conclude annihilation is the correct doctrine. The wicked are destroyed forever (Psalm 92:7), not forever being destroyed.
Yeah, it refers to maggots that unceasingly feast upon corpses...you know, *dead* bodies.
