THE MYSTERY OF HELL AND THE LAKE OF FIRE: ARE THEY THE SAME?

After the first death, we wait in sheol/hades/hell until judgment. There are separate dwellings there for the righteous and the unrighteous. Those deemed righteous will rest in peace, but the unrighteous will be tormented. No rest in peace.

Then at the judgment it gets even worse for the sinner: a final sentence to the lake of fire which was prepared for the devil and his angels.
What is ironic, is that some Christians believe when they die they go to heaven. Instead, when we die, we all go to hell first, just as the Messiah did (1 Peter 4:5-6, Ephesians 4:8-10). Then after the judgment we will either go to the lake of fire or into the kingdom of heaven (which will be here on earth). All this depends on the judgment.
