Ezekiel, Jeremiah, Daniel and Zechariah are prophets that speak in parables about the future not the past. They speak in symbolism about the final war on Earth.
Jeremiah explains in the final war "cease fire" (WW3 is the fire), survivors realize their fathers taught them falsehoods that their Christ, son of David would save them to establish a kingdom. The baptism by fire is the Devil's baptism because people have taken the mark of the Beast which is to agree to fight in a thermonuclear war.
WW3 destroys the EARTH that will become unable to sustain biological life.
Jesus leads people to the water of life. The Son of man, supporter of Abraham/David, denier that Jesus is the son of God, leads people to the eternal fire of self sustaining nuclear fission that covers the Earth with flesh burning radiation. He steals the name of Jesus Christ just like Jesus warns he will, the prince with nothing in him.
2 Gods,
The merciful true God has nothing to do with the final war and left Earth when people hung his Beloved Son on a cross for sins he did not commit like calling himself God's Son. God left with signs what is going to happen to Earth because Jesus was murdered and millions support the murder.
The other "God" is Lord God, the fake God Abraham invented and his supporters demand nuclear war to take what does not belong to them like a thief in the night.
The "survivors" of the "nations" who went up against Jerusalem (Zechariah 14), will come to Jerusalem year to year to keep the feast of Tabernacles (Zech 14:16). The "nations" which went up against Jerusalem will have their gold and silver confiscated (Zech 14:14), but only after they undergo the plague of radiation poisoning of which "the LORD" will bring upon them (Zech 14:12). It is the LORD who "will gather all the nations against Jerusalem" (Zech 14:2), as paralleled in Joel 3:1-2 after Judah, the Jews, and Jerusalem has been "revived". As for the coming "furnace of fire", the "great Tribulation", that will be "cut short" (Matthew 24:22) so that the "elect" will not perish. As to who are thrown into the "furnace of fire", that would be those who "commit lawlessness", which are the tares, who follow the message of the "enemy"/"devil" (Matthew 13:38-42), which would be the message of the false prophet Paul. As for Jeremiah 16:19, it is the survivors of the "nations"/Gentiles who confess that they have followed "falsehoods"/lies. I am not sure which sect you get your specific doctrines, but it would be interesting to know.
