Lucas, your question is a very fair one. But I am not going to give you the popular answer, because the Truth is NEVER popular.
The Truth is that the fire and brimstone eternally for the damned is NOT a Biblical teaching. It was invented sometime around the time of the legalization of Christianity in Rome, for precisely the purpose of gaining converts through scare tactics.
The Bible talks only about Heaven, as referenced in the verses above, and The Second Death and Eternal Fire.
Now let’s define the latter two...
The Second Death is destruction of the Soul. There is nothing after that for the lost soul, simply because it ceases to exist (Revelation 2:11, Rev 20:6 & 14, and Rev. 21:8)
The Eternal Fire referenced in the Bible is the same “Eternal Fire” than consumed Sodom and Gomorrah... Are Sodom and Gomorrah still burning or even smoldering? NO.
In essensce, what is being said is the consequences are ETERNAL, not the physical act of burning Eternally. (Jude 1:7)
Lastly, the Book of Ecclesiastes states that Death, that is the First Death, defined by death of the physical body, is merely a sleep. (Ecclesiastes 9:5)
There is no consciousness in being dead physically or spiritually.

Revisionist history.
"And there came down fire from God out of heaven, and devoured them; and the devil, who seduced them, was cast into the pool of fire and brimstone, where both the beast And the false prophet shall be tormented day and night for ever and ever." Apocalypse 20:9-10
The Bible talks only about Heaven
Only if you skip large portions of Scripture.
