According to Christianity, after death, believers go to heaven to be with God for eternity, while non-believers face judgment and may go to hell.
The word eternally is an adverb. It means to do something for eternity.
Eternity means "lasts forever" while infinity means "without end". Neither one exists (the current age of `everything' is a mere 13.7 billion years); but in pure math terms, infinity trumps eternity.
The message of Christianity is if we know God and love Him we will live with Him in eternity.
"Eternity" means that it never ends - in other words, the number of seconds, or years, or days, or whatever, is infinite.
In Christianity, hell is the state of being separated from God for all eternity, that is it's worse pain, but there are many other pains. The primary truth about it is that is 1) a state of being, not a place, and 2) it is eternal, meaning that it never ends, and there is no time (time is just a measure of change). All of which means that No, people do not die in hell, they exist in that state for eternity.
The message of Christianity is to fulfill the Great Commission which states, "Therefore, go and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit" (Matt. 28.19).
