The bible doesn’t say the afterlife is permanent, when people die they are awaiting the resurrection. The righteous go to paradise awaiting the 1st resurrection/rapture when they get new heavenly bodies (1 Cor 15:12-58, 1 Thess 4:13-18, Heb 11:32-35, Rev 20:4-6). Meanwhile the unsaved await the 2nd resurrection in Hell/Hades/Sheol, which then leads to the second death in the Lake of Fire (Rev 20:4-6, Rev 20:11-15). Hell/Hades/Sheol is a temporary holding place of the unsaved until the 2nd resurrection [of the wicked] (Rev 20:4-6, Rev 20:11-15). Then the wicked are condemned to the Lake of Fire, along with Satan; joining the Anti-Christ and False Prophet who were thrown in beforehand. Revelation 19:20, 20:10-15, and 21:8 explain the Lake of Fire and say the hell itself is also thrown into the Lake of Fire on judgment day, which means there are two separate locations and only one of them is a permanent stay.
